Betrayal Wears Many Faces

Summary:

At eighteen, Marinette Dupain-Cheng is the Guardian of the Miraculouses, a successful designer under the pseudonym MDC, and completely alone. Lila's lies have destroyed her reputation, turned her friends against her, and made Paris suffocating. When Wayne Enterprises offers her a collaboration program in Gotham, Marinette takes the escape—planning to portal back for akuma attacks while building a new life far from the toxicity.

What she doesn't expect is Damian Wayne: brilliant, dangerous, and somehow able to see past every mask she wears. As Marinette falls for the boy who brings her coffee every morning, Ladybug finds an unexpected partnership with Robin on Gotham's streets. Two identities, one person, and a romance that might finally give her a reason to believe in happiness again.

With Hawk Moth's defeat on the horizon and secrets between them, Marinette will have to decide: keep hiding, or trust someone with the truth for the first time in months.

Notes:

Chapter Text

 

Marinette Dupain-Cheng stared at her reflection in the floor-length mirror of her atelier, barely recognizing the exhausted eighteen-year-old looking back at her. Dark circles shadowed her eyes, and her shoulders curved inward as if she were trying to make herself smaller, invisible. Her hair, usually styled in playful pigtails or an elegant updo, hung limp around her face. She looked haunted.

Her phone buzzed for the hundredth time that hour. She didn't need to look to know what it was—more messages, more accusations, more of Lila Rossi's poison spreading through her former friend group like a disease. Against her better judgment, Marinette picked up the phone. The notifications made her stomach churn.

@AlyaLadyblogger: New post: "When Your Best Friend Isn't Who You Thought - My Experience with Manipulation and Lies" #TruthMatters #Disappointed

@NinoLahiffe: Dude, Alya showed me everything. The fake charity receipts, the photoshopped images of you stealing Lila's designs, the screenshots of you "cyberbullying" her. How could you?

@RoseValentine: Marinette, Lila's in the hospital again because of the stress you've caused her. Her lying disease is acting up. How can you live with yourself?

@MaxKante: The statistical evidence Lila provided is quite damning. I've calculated a 97.3% probability that her accusations are accurate.

@KimLePhan: Never thought you'd stoop this low, Dupain-Cheng. Alix won't even talk about you anymore.

Marinette's hand trembled as she scrolled through more messages. The group chat she'd been removed from had 247 new messages, all visible in the preview notifications. She caught glimpses:

"can't believe we trusted her,"

"always knew there was something off,"

"Lila was right all along."

She set the phone face-down on her cutting table. The screen went dark. Good.

It had started small, six months ago. Lila had returned from her "trip to Achu" with new stories, new connections, new lies. But this time, she'd been smarter. She'd learned from her past mistakes when Marinette had exposed her before.

This time, Lila had evidence.

Fabricated, photoshopped, completely falsified evidence—but evidence nonetheless.

First, it was the charity incident. Lila had claimed to organize a fundraiser for a children's hospital, collected money from their classmates, then claimed Marinette had stolen the donations. She'd even produced fake bank statements showing transfers to an account under Marinette's name. An account Marinette had never opened, but try proving that to teenagers who wanted to believe.

Then came the design theft. Lila had somehow gotten her hands on early sketches of Marinette's MDC designs—probably from hacking her cloud storage—and claimed they were her own concepts that Marinette had stolen. She'd even created a fake portfolio with timestamps that predated Marinette's work.

The cyberbullying accusations were perhaps the cruelest. Lila had manufactured entire conversations, complete with a fake account using Marinette's name, sending hateful messages. She'd even gone so far as to bruise her own arms and claim Marinette had physically attacked her, though she'd conveniently never reported it to authorities—"because I still care about her and don't want to ruin her future."

Every lie was crafted perfectly, designed to paint Marinette as a jealous, vindictive bully who couldn't stand seeing someone else succeed.

Everyone believed it.

Alya, her former best friend, had written a scathing exposé on the Ladyblog about "toxic friendships and recognizing manipulation." She'd detailed years of Marinette's "jealous behavior" toward Lila, reframing every instance where Marinette had tried to expose the liar as evidence of her obsessive hatred. The comments section had thousands of supportive messages for Lila and vitriolic attacks on Marinette.

Marinette pressed her palms flat against the cutting table and breathed. She wouldn't cry. Not again. She'd shed enough tears over people who'd never truly known her, who'd chosen to believe lies over years of friendship.

The worst part? She couldn't even defend herself properly. Because doing so would mean revealing she was MDC, and that would only give Lila more ammunition. The girl would claim Marinette was lying about being the designer, or worse, would find some way to sabotage her career entirely.

So Marinette stayed silent, took the abuse, and watched her social life crumble to dust.

"Marinette?"The soft voice broke through her spiraling thoughts. Tikki floated up from her hiding spot among the fabric swatches, her large blue eyes wide and filled with a worry she didn't try to hide. Behind her, the Miracle Box hummed quietly on the worktable—the complete set, every last Miraculous accounted for, something no Guardian in living memory had managed.

One by one the kwamis drifted out: Wayzz with his slow, steady presence; Trixx bright-eyed and unusually subdued; Pollen hovering with her tiny hands clasped together; Longg coiling through the air in a quiet spiral; Roaar padding silently onto the worktable's edge; Ziggy, Stompp, Fluff, and Sass emerging in a cluster. And then, quieter than the rest, Nooroo—his soft violet wings tucked close, still carrying that particular gentleness of someone who had been used as a weapon for too long and was only now learning what safety felt like. Beside him, Duusu, her feathered form still occasionally flickering at the edges with the instability that months of a cracked Miraculous had left behind. She was getting better. Slowly. All of them watching their Guardian now with the same careful, heartbroken attention.

"I'm fine," Marinette said automatically. The words came out flat, rehearsed. The lie tasted bitter on her tongue even as she said it.

"You're not fine." Plagg's voice was a drawl from somewhere behind her, unimpressed and matter-of-fact. He floated over from where he'd apparently been napping on a bolt of black silk, his green eyes sharp despite his lazy posture.

He was hers now—had been since Adrien had pressed his ring into her palm on that rooftop two months ago—and he'd settled into her atelier with the particular ease of someone who had decided not to make a fuss about something that quietly devastated him. He swiped a piece of cheese from the stash she kept specifically for him and fixed her with a look that was, for once, entirely serious. "You've been 'not fine' for months now, Pigtails. That liar has done a number on you."

Marinette opened her mouth to argue. Closed it again. What was the point? He was right. They were all right. The worst part wasn't even Lila's lies anymore. Marinette had learned to expect cruelty from the liar, had built up walls thick enough to absorb the daily venom that Alya and the others aimed at her. She'd gotten good at that—at going still inside, at letting the words roll off like rain off glass.

No. The worst part was three weeks ago, when she'd finally broken down and told her parents everything. She'd shown them the evidence of Lila's manipulations, walked them through every fabricated document, every falsified timestamp, every screenshot. She'd cried—actually sobbed in her mother's arms, ugly and desperate—and begged them to believe her.

They hadn't.

"Marinette," her father had said, his broad hands wrapped around a mug of tea he wasn't drinking, his voice heavy with something that sounded terrifyingly like disappointment, "we've had three teachers call us this month. Principal Damocles. Mrs. Rossi herself, in tears, begging us to get you help."

"But Papa, she's lying—" Marinette had reached for his arm, her fingers curling around his sleeve.

"Enough!" The word cracked through the kitchen like a thunderclap. Sabine stood at the counter, arms crossed, her small frame rigid. Normally so gentle, so warm—the mother who tucked notes into Marinette's school bag and hummed while she rolled dough—she looked at her daughter now with exhaustion etched into every line of her face. "We've watched you become obsessed with this girl. Your grades slipping, spending all your time on this fashion thing instead of focusing on your future—"

"My fashion thing?" Marinette had stared at her, the words landing like a slap. "Maman, I'm successful. I have clients. I'm making money—"

"Money you're secretive about." Tom had set down the mug then, carefully, and shaken his head. He looked tired in a way that went deeper than one bad night. "Money from who knows where. And this MDC persona you've created—sweetheart, we think you might be... unwell. Creating this fantasy where you're some famous designer while your real life falls apart around you."

The bottom had dropped out of Marinette's world.

"You think I'm making it up?" Her voice came out very small. Broken at the edges. "You think I'm lying about being MDC?"

"We think you're struggling." Sabine's eyes were soft, and somehow that was worse than anger would have been—the pity in them, deep and certain. "The constant conflict with Lila, this fixation on being someone you're not, the paranoia that everyone is against you. These are signs, Marinette. We want to help you, but first you need to admit you have a problem."

Something inside Marinette had shattered then. Not loudly. Not all at once. Just a quiet, fundamental cracking—the sound of a belief she'd held her whole life giving way. Her parents were supposed to know her. Supposed to love her unconditionally. They thought she was delusional.

"We've made an appointment with a therapist," Tom had continued, drawing a business card from his shirt pocket and setting it on the table between them like a peace offering. "Dr. Bernard specializes in teenagers with... creative disorders. Compulsive lying, delusions of grandeur—"

"I'm not lying!" The words tore out of her raw and ragged, her voice cracking on the last word. She was on her feet without remembering standing. "I'm not delusional! I am MDC! Lila is the liar, and you—you're supposed to believe me! You're supposed to be on my side!"

"We are on your side, sweetheart." Sabine had reached for her then, her hand outstretched, her expression unbearably gentle. Marinette had jerked back so hard she nearly knocked over her chair. "That's why we're doing this. We love you too much to watch you destroy yourself."

"If you loved me," Marinette had said, her voice dropping to something hollow and quiet, "you'd believe me."

Tom looked at her for a long moment. His eyes were sad. "If you loved us," he said, just as quietly, "you'd stop lying."

Marinette had run to her room and hadn't come back down that night. Or the next. She'd started taking her meals alone, leaving early and coming back late, reducing her parents to brief necessary exchanges about schedules and groceries. The appointment card for Dr. Bernard sat on her desk where Tom had left it, face-up, a constant small cruelty she couldn't bring herself to throw away.

The irony was crushing. She'd been protecting Paris for years—had saved her parents' lives more times than she could count, stood between the city and disaster again and again—and they didn't even believe she could design clothes.

Now, sitting in her atelier with the kwamis gathered close and the city glowing gold outside her windows, Marinette felt the weight of that betrayal like a physical thing pressing down on her chest.

"You're thinking about them again," Tikki said softly. She landed on Marinette's shoulder, her tiny feet light as a breath, and leaned her head against Marinette's cheek.

"How could they not believe me?" Marinette's voice came out barely above a whisper. She kept her eyes on the middle distance, not trusting herself to look at any of them. "I'm their daughter. They raised me. They should know I wouldn't lie about something like this."

"Lila is very convincing," Wayzz offered from his spot near the Miracle Box, his aged voice careful and gentle. "And humans... they often believe what is easier to accept."

"It's easier to accept that their daughter is mentally ill than that she's telling the truth?" Marinette let out a laugh—short and sharp and entirely without humour. "That's messed up, Wayzz."

"Kid." Plagg floated directly in front of her face, forcing her to focus on him. His expression had dropped all pretense of laziness. For a kwami of destruction, he could look startlingly sincere when he chose to. "Your parents are idiots. But you know what? You don't need them. You've got money from MDC, you've got us, and you've got a way out of this toxic wasteland."

Marinette held his gaze for a moment. Then she turned to her laptop.

The Wayne Enterprises email was still open, cursor blinking patiently in the reply field. An invitation to participate in a month-long designer collaboration program in Gotham City—they wanted emerging designers to create collections inspired by Gotham's unique aesthetic, its gothic architecture, its art deco bones, the tension between old-world grandeur and modern grit. It was a prestigious opportunity. Career-defining, even.

But more than that, it was an escape.

She was eighteen. Legally an adult. She had money—real money, from real clients, not the fantasy her parents had decided she'd invented. She could accept the Gotham program and use it as a stepping stone to something bigger. She didn't need their permission.

But god, it hurt that she didn't have their belief anyway.

"I'm doing this." The words came out steady. Steadier than she felt. "I'm accepting the Wayne program. And I'm not coming back."

"What about your things? Your room?" Tikki pulled back to look at her properly, her brow furrowed with worry, wings fluttering in agitation.

"I'll pack what I need. The fabric, my designs, my equipment." Marinette's jaw tightened. She could feel the decision settling into her bones, solid and irreversible, and something about that steadied her. "I'll use my MDC money to get an apartment there, set up a real studio." She looked around the atelier—the slanted skylight, the pin-boards covered in sketches, the worn patch on the floor where she always stood when she was thinking. The space above her parents' bakery where she'd grown up. "Paris isn't home anymore."

"What will you tell Tom and Sabine?" Wayzz asked carefully.

"The truth. That I'm going to Gotham for the Wayne program." She pulled up the email and began typing her acceptance, her keystrokes quick and certain. "They'll probably think it's another delusion. I don't care anymore. I'm eighteen. I don't need their permission to leave."

"They'll be upset," Tikki said quietly. She hadn't moved from Marinette's shoulder, and her small hand rested against Marinette's neck like an anchor.

"They're already upset. They think I'm crazy." Marinette hit send. Watched the confirmation flash across the screen. Something in her chest loosened—just slightly, just enough to breathe. "At least in Gotham, I'll be crazy and successful and far away from people who've already decided who I am."

The kwamis exchanged glances. None of them argued. They'd all watched the change happen over these past months—the way the light had slowly gone out behind Marinette's eyes, the way she'd stopped laughing, stopped reaching out, stopped expecting good things from the people around her.

Lila had started it. The class had made it worse. Her parents' betrayal had broken something fundamental. Maybe Gotham, dark and dangerous and nothing like Paris, would be the place where she could start putting herself back together.

At eighteen, she should have been celebrating. She was the Guardian of the Miraculouses—a responsibility she'd earned through years of sacrifice and stubborn, relentless hope. Two months ago, she and Chat Noir had finally done it: they'd unmasked Hawk Moth

Gabriel Agreste.

Taken back the Butterfly Miraculous and the Peacock, freed Nooroo and Duusu from years of forced servitude, and closed the chapter on an era of akumas that had terrorized Paris for as long as Marinette could remember. She'd decoded Master Fu's grimoire, mastered abilities that previous wielders had only read about in theory, and brought home every last Miraculous to the complete set that now sat in the Box on her worktable. She had done the impossible. She had won.

There was not a single person in her life who knew it, or who would have believed her if she'd said so. She remembered the moment it had ended. Not the battle itself—that was a blur of motion and desperation and finally, finally landing the hit that mattered. She remembered after. The way Gabriel Agreste had crumpled, the Butterfly Miraculous skittering across the rooftop stone. The way Chat Noir had gone very still beside her.

And then he had reached up and taken off his ring.

She hadn't understood at first. She'd watched him turn it over in his fingers, this boy who had fought beside her for years, and then he'd looked at her—really looked at her, with green eyes she'd never seen without the mask—and held it out.

"I can't do this anymore," Adrien Agreste had said. His voice was wrecked. Hollow in the way of someone whose entire world had just been dismantled in front of them. "I'm sorry. I just—I can't."

She hadn't said anything. What was there to say? His father was Hawk Moth. The man who had terrorized Paris, who had turned grieving people into weapons, who had made Marinette's life a battlefield for years—that man had been tucking Adrien in at night. Had been sitting across from him at dinner. Had been the reason Adrien smiled that careful, practiced smile that never quite reached his eyes.

Plagg had drifted out of the ring the moment it left Adrien's hand, and had looked between them both with an expression Marinette had never seen on him before. Old and tired and sad.

"Kid," Plagg had said softly. Not to her.

"Take care of him," Adrien had said to the kwami. Then he'd looked at Marinette one more time—at Ladybug, at the mask, at the person he'd never known was Marinette Dupain-Cheng—and said, "Thank you. For everything."

He'd detransformed fully, stepped into the chaos of the aftermath, and let the crowd swallow him up. She'd heard later, through the same city gossip that had once spread Lila's lies, that Adrien had gone to live with his aunt and cousin in England. That he'd left Paris entirely—the modelling, the school, the empty mansion—and was trying to learn who he was without his father's hand shaping every part of him. That he was, by all accounts, doing better.

She was glad. She genuinely was.

But…as she had also stood on that rooftop holding his ring and Plagg both, with the weight of every Miraculous suddenly hers alone, and understood with a clarity that left no room for argument that she was completely, utterly on her own now. Her partner—the one constant she'd had through every akuma, every impossible night, every moment she'd doubted herself—was gone. And he didn't even know that the girl he'd left behind was already drowning.

He didn't know, because they had kept their identities secret right up until the very last moment. He knew Ladybug. He didn't know Marinette.

And Marinette couldn't even be properly angry about it, which somehow made it worse.

But Marinette Dupain-Cheng? That girl was falling apart.

And now, she was giving herself permission to leave.

She crossed to her design wall and ran her fingers over the sketches pinned there—the latest collection, bold and strange and entirely hers. Pieces that pushed against every boundary fashion had told her to respect. Works of art that had caught the eye of people who knew the difference.

Works that her own parents thought were delusions.

MDC. That's what the fashion world called her. Three letters that had become synonymous with a fresh eye and an instinct that couldn't be taught. At eighteen, MDC had dressed celebrities, had pieces in Vogue and Elle, had a waiting list that included everyone from Jagged Stone to Clara Nightingale. The industry talked about her like a mystery—who was she, where had she come from, when would she finally show her face?

Not one of them knew that MDC was Marinette Dupain-Cheng. The girl her classmates had written off as a liar and a bully. The girl her own parents thought was mentally unstable.

The irony would have been funny if it didn't hurt so much.

"You know what the worst part is?" Marinette said, her voice quiet and conversational, like she was commenting on the weather. Her fingers traced the edge of a sketch without really seeing it. "Lila's been telling everyone she has connections to MDC. That she's practically my muse. My parents have heard those exact lies, and they believe Lila has those connections more than they believe I'm actually the designer."

"Of course they do." Trixx drifted down to perch on top of the pin-board, his rust-coloured tail curling around his feet. His voice, usually full of mischief, was stripped of it entirely. "They've believed everything else she's said."

Marinette's phone buzzed again on the cutting table. She didn't pick it up. She already knew what it was—another message, another lie, another small knife she was supposed to just absorb and move on from.

She turned away from it and started pulling out suitcases instead.

She packed with mechanical precision, sorting as she went—what would travel with her, what could be shipped, what could be sold or stored. No hesitation, no second-guessing. The girl who'd spent an hour crying over a single cruel comment had packed herself away somewhere deeper, somewhere the messages couldn't reach.

"Marinette." Tikki's voice was very soft. She landed on a folded bolt of fabric at the edge of the open suitcase, looking up at her Guardian with eyes that held everything she wasn't saying. "You don't have to do this alone. We're with you."

Marinette's hands stilled over a stack of pattern pieces. She looked at them—all of them, hovering nearby or perched on various surfaces, watching her with the kind of steady, unconditional attention she hadn't felt from anyone else in months. Her friends. Her family, in every way that mattered.

"I know," she whispered. Her throat tightened. "And I'm grateful for that. More than you know."

She went back to packing.

The Wayne program started in a week, which gave her enough time to find an apartment, arrange shipping for the heavy equipment, and disappear before her parents realized she was serious. They'd probably be relieved, she thought, folding a piece of silk with more care than the moment deserved. No more troubled daughter underfoot. No more phone calls from the school. They could go back to their bakery and their routines and their version of reality where Marinette was the problem.

"You know what?" she said, more to herself than to any of them. "Maybe this is good. Maybe I needed to lose everything to figure out who I actually am."

"And who are you?" Wayzz asked gently, in the tone he used when he already knew the answer but wanted her to find it for herself.

Marinette looked up at her reflection in the mirror across the room. Eighteen years old. Dark circles. Shadows under her eyes. Shoulders that had been carrying too much for too long.

Still standing. Still fighting.

"I'm the Guardian of the Miraculouses." Her voice came out quiet, but it didn't waver. "I'm Ladybug. I'm MDC." She lifted her chin, meeting her own gaze in the glass. "I'm someone who saved Paris every day, even if Paris doesn't know it. Even if Paris doesn't need me anymore. I'm someone who built something real from nothing. I'm someone who's going to Gotham and starting over."

"Alone," Tikki said quietly. Not an accusation. Just the truth, spoken gently.

"For now," Marinette agreed. "But maybe... maybe I'll find people in Gotham who actually see me. Who don't have six months of Lila's lies already written across their faces when they look at me. Who might actually believe me when I tell them the truth."

It was a fragile hope. Barely there. But it was something, and Marinette had learned a long time ago that something was enough to keep moving.

As she packed, the sun finished setting over Paris outside her skylight, and the city went from gold to grey to the deep familiar blue of evening. She let herself feel it—the grief, the anger, the bone-deep exhaustion of loving people who hadn't loved her back the way she needed. She let herself mourn the friendships that had turned out to be conditional, the family that had chosen a stranger's word over hers, the version of her life she'd imagined and would now never have.

She felt all of it. And then she folded it up, tucked it away, and kept packing.

She was Marinette Dupain-Cheng. She refused to break.

What she didn't know—couldn't know, not yet—was that Gotham had its own protectors. That the city's darkness sheltered more than just criminals and shadows. That in one week, she would meet someone who would see through every careful wall she'd built without even meaning to.

Someone with green eyes and a katana. Someone who understood what it meant to be failed by the people who were supposed to claim you. Someone who fought in the dark and cared with an intensity he didn't have the first idea how to soften.

Someone named Damian Wayne.

But that was still seven days away.

For now, Marinette allowed herself one last look around the atelier—the slanted light, the pin-boards, the worn floor, the city spread out beyond the glass—and said goodbye to it without words.

Then she turned back to her suitcase, and didn't look again.

Gotham was dangerous. Gotham was dark. Gotham was everything Paris wasn't.

Right now, that sounded exactly like what she needed.
