XOXO

Summary:

Based on the chat where Mammon gets a letter that he thinks is from MC.

MC writes Mammon letters confessing her feelings for him, and he tosses them aside, thinking they're all from Lucifer.

Notes:

This was requested for me on tumblr.

I post more stuff on there and usually before I post it here :)

Work Text:

“Here,” MC said, standing in front of Mammon. He was sprawled out on the couch in the common room scrolling through his D.D.D. He looked up, cocking an eyebrow at the pretty girl before him.

She tossed the envelope in her hand down to him and it landed in his lap.

“What’s this?” Mammon asked, turning the envelope over in his hands.

“Just…read it in your room, okay? Not out here.”

Mammon felt his heart flutter as MC walked off, leaving him there to hold the envelope in his hand.

A sealed envelope from MC…that he was to read in his room? Mammon couldn’t help the smile that spread across his face. A love letter…MC just gave HIM a love letter!

Mammon’s heart was beating, his hands shaking as he gripped the letter, speed walking to his bedroom and shutting the door behind him. He leaned against the door, holding the letter to his chest.

An actual love letter. From MC.

Finally, it was confirmed. MC felt the same for him as he felt for her. I need to get her a present, Mammon thought. Something nice. Something expensive.

But first, he had to brag.

(Mammon:) Ahem.

Oh boy, he couldn’t wait till his stupid brothers heard about this.

(Mammon:) AHEM!

(Mammon:) HEY! Someone say somethin’!

(Belphie:) No way. I get the feeling it’s going to be something annoying.

(Levi:) Yeah, tell me about it.

Mammon scoffed. Rude. Every last one of ‘em.

(Mammon:) A-H-E-M!

(Satan:)Okay, fine. I don’t care what it is, so just say it already.

(Asmo:) It sounds like he wants to brag about something.

Mammon smiled proudly, sending the ‘Yes!’ sticker.

(Mammon:) Listen up and be amazed! I, The Great Mammon, have received a love letter from MC!

(Belphie:) Huh?

(Levi:) He must be hallucinating again.

(Mammon:) I’m not hallucinatin’! It’s a letter inside a pretty lil envelope? What else could it be besides a love letter?

(Beel:) you mean you haven’t opened it yet?

(Mammon:) Well, it’s kinda sealed shut. Besides, can’t a guy savor the moment a bit before he opens it?

(Belphie:) Wow, I never pegged you as the type.

(Mammon:) Hey! Whaddya mean by that?

I’ll have ya know I’m quite the gentleman! Besides, MC told me to read the letter by myself in my room ❤

And that’s exactly what I plan on doin’.

(Satan:) Well open it up then, “Mr. Gentleman”

(Levi:) Yeah, I don’t think you will be savoring the moment for long after you take a look at what’s inside.

(Mammon:) Ugh, fine! Gimme a moment.

Mammon took a deep breath, shakily and carefully opening the envelope. This was it. He’d finally know for sure that she returned his feelings. Then, she’d be his, and only his. It was like a dream come true, he’d be able to hold her, kiss her, and go on dates with her.

He pulled the letter out and unfolded it.

The demon’s face fell, and he sank to the floor, holding the letter in one hand and the envelope in the other.

(Belphie:) Mammon’s grown awfully silent.

(Lucifer:)That is because the ‘love letter’ is from me. Although I call it an “official written demand of repayment.”

(Levi:)Ha! What a noob, lol.

Mammon felt an aching in his heart and tears started to fall from his eyes, landing on the long list of debts. Every ounce of excitement, of hope, every thought of he and MC being happy and in love, shattered. Mammon balled up the paper and threw it across the room.

He was angry at Lucifer, but he expected something like this from Lucifer. But not MC. MC didn’t make fun of Mammon like his brothers did. She never called him stupid or scum. She even stood up for him most of the time. Mammon couldn’t believe MC was a part of this cruelty. That hurt a hundred times more than anything his brothers could say to him, any torture Lucifer had for him.

Mammon wiped his eyes, getting up to grab his precious Goldie. He stormed out of the house, determined to max out the credit card to get his mind off MC’s betrayal.

“I haven’t seen Mammon in a couple days,” MC stated at breakfast, looking over at the chair next to her where the second born always sat.

“Oh, he ran off to sulk,” Lucifer replied nonchalantly. “I gave him a list of things he needs to pay off.”

“Is that what was in the envelope you had me give to him?”

“Yep.”

Leviathan’s laugh interrupted the conversation. “That moron thought it was actually from MC. As if MC would be interested in a scumbag like Mammon.”

“Wait, wait, wait,” MC shook her head. “You gave me a letter to give to Mammon so he’d think it was from me?”

 

“Of course. Why else would I have you deliver it?”

“I just thought it was because I’m always with him.”

“Sure,” Satan offered up, “But also if Mammon knew the letter was from Lucifer, he wouldn’t have opened it.”

“Exactly,” said Lucifer, agreeing with Satan for once.

“That’s kinda fucked up, don’t you think?”

“Mammon’s fucked up,” Satan responded.

Asmo sighed. “Seriously MC, I don’t know why you’re so close with Mammon. He acts nice to you, but he’d sell you for a few Grimm.”

MC scoffed. “No, he wouldn’t.”

“Mammon is scum,” Levi spoke up again. “Don’t feel bad for him.”

“Wow,” MC replied, getting up to leave. “You should all really think about how you treat Mammon.”

Heading back to her room, she grabbed a pen and notebook out of her backpack and sat down to write.

Mammon,

I heard you wanted a letter from me.

I’m so sorry that your brothers are dicks to you. I don’t think you’re scum, Mammon. I think you’re sweet and smart and funny, and I love spending time with you.

You’re pretty much my best friend.

Love, MC

P.S. Sorry for giving you that letter from Lucifer. I didn’t know what he was up to, I promise. Xoxo

She sealed in it an envelope and wrote his name with a heart. She snuck to Mammon’s room and set it on his pillow. MC was a bit embarrassed by what she wrote, hoping he wouldn’t find it creepy or weird. She wished that he’d be back soon.

**

Mammon snuck in late after being gone for a week, body and head exhausted and hungover, he crawled into bed and passed out.

When he woke up, he yawned and stretched before noticing the letter on the bed next to him. He picked it up, scoffed, and tossed it across the room.

There was a new envelope everyday.

Somedays, MC would slip them under his door. Sometimes she’d hand them directly to him. They’d be waiting for him in his room, on his bed again, on his couch. Each time, Mammon would feel a pang in his stomach. He so badly wanted to open them. Maybe one would actually be a letter from her.

But of course it wouldn’t be.

MC would never see him like that. Why would she? Mammon was nothing but a greedy, scummy, piece of shit. His brothers made that clear, and now they had MC joining forces with them.

So the pile of letters grew, a small mountain of various colored envelopes.

When he gets one with a lipstick kiss on the envelope, Mammon loses it. He grabs the pile of discarded envelopes and storms to Lucifer’s office, dumping all of them onto the desk directly on top of whatever Lucifer was working on.

“Mammon, what the f-”

“Ya gotta stop doin’ this to me, Lucifer. Look, I’ll repay everything. I’ll go get a job or something, but please, please, stop getting MC to give me these. I get my hopes up and I know they’re just bills and I can’t anymore. It’s killin’ me.”

Mammon was embarrassed at how emotional he was being, whining and crying to his older brother.

Lucifer stared at the envelopes. “Mammon, these aren’t from me.”

“Whaddya sayin’! Of course they are!”

“No, they’re not.” Lucifer picked up one and ripped it open.

Mammon,

I know you don’t read these which I guess is why I keep writing them. I know that makes no sense. But it helps to write about my feelings for you. It’s a relief to be able to tell you how much I love you, cause I know I can never do it in person.

xoxo,

MC

“Oh…um, Mammon. I think you should read these.”

“You guys are probably just playing tricks on me again.”

Lucifer shoved the letter in Mammon’s face. Mammon wiped his eyes and read over the letter, his heartbeat speeding up.

“This is really her handwriting,” he said in shock.

Lucifer nodded.

“The stupid human really wrote all of these.”

Mammon grinned like mad, gathering all of the letters and rushing back to his room. He threw them onto his bed and sat, cross legged, reading each and every one of them.

A few of them were simple doodles of the two of them and Goldie. Most of them had words of encouragement for him, telling him that she thought he was sweet and a good person (Despite being a literal demon). In every single one was confessions of love and appreciation.

Mammon brought out his D.D.D. and text MC, telling her to come to his room.

MC was thrilled to get a text from Mammon. They hadn’t been spending a lot of time together, and he had barely spoken to her since the day of the first letter. MC slipped on some leggings and an oversized t-shirt and got to Mammon’s room as quickly as she could.

When she saw the opened letters on the bed with him, she grew red. Oh shit.

“Um…you opened the letters.”

Mammon nodded. “Whaddya thinkin’, writing letters like this for me?”

“Mammon, I’m sorry…just f-forget you ever read them.”

“Are you kiddin’ me? You’re the only one who’s ever nice to me, ya know? And now I know how you really feel…”

MC groaned, hiding her face in her hands.

“Of course ya like the Great Mammon! Everyone does. But, uh, iloveyoutooMC.”

“Wait, what?” MC peeked from behind her hand. “Did you just say…”

“Yeah, yeah. Come ‘ere, you!”

Mammon gently grabbed MC’s arm, pulling her to him and pressing his lips to hers. She smiled against his lips. They fell back onto his bed, ripped envelopes and love letters crumbled underneath them. MC rested her head on Mammon’s chest as he pulled her close, both of them smiling wide.

“Does this mean I can stop writing you letters?”

“Ya better not! I expect one first thing tomorrow.”

Mammon planted a small kiss on the top of her head.

Finally, he knew for sure that the human was his.
