Tomorrow

Summary:

"Aren't you scared, Kacchan?"

Izuku's voice sounded calm, so Katsuki allowed himself to relax too.

"Who do you think you're talking to, nerd? Someone who pretends to be Japan's greatest hero can't be afraid," Katsuki replied with mock arrogance. He knew it: being number one didn't mean not being afraid, but rather acting despite being afraid. But today he needed to pretend that fear didn't exist, or panic would devour him. Izuku chuckled softly.

"I'm talking about a different kind of fear. I'm terrified of the thought that I could die without having experienced some things that were supossed to be normal."

"We go through a lot more than anyone else our age."

"And those people also experienced a lot of things we didn't."

"Where are you going with this, Izuku?"

Work Text:

It was kind of easy to pretend it was just another day; they were just high school teenagers having normal classes, joking around, and deciding to watch a movie together in the common room. They all felt the heavy atmosphere of uncertainty and fear, not really paying attention to the movie's plot, but they wanted to pretend just a little longer that tomorrow they weren't going to be sent to war against the worst villain the world had ever seen.

And although, as students in the UA Hero Course, knew that the day would come when risking their lives would be their everyday possibility, they never imagined it would happen so soon. They were sixteen years old! That society had fallen to the point where all hope rested in their hands—was it really necessary? To send them against the very villains who had murdered professional heroes? Even their own teachers?

The only thing that couldn't be hidden were the worried glances directed at Izuku; he bore the weight of wielding the power of All Might himself, the responsibility of being the one who had to kill Shigaraki and One for All as soon as the opportunity arose. The entire Class 1-A was prepared to give their all to pave the way for Izuku, but that didn't diminish the fact that the most difficult task lay with the successor to Japan's number one hero.

That's why they didn't say anything when Izuku simply stood up without a word and disappeared into the elevator, probably going up to his room. He needed time to think, and everyone understood; except Katsuki, who didn't hesitate to follow him a few minutes later.

Katsuki knew he wouldn't find him in his room; Izuku liked open, solitary places when he needed to calm his anxiety, places where a cool breeze would keep his mind connected to his body, so he went straight to the rooftop where he found Izuku sitting on the edge of the building.

"Don't even think about jumping, you bastard," Bakugo's voice startled Izuku slightly, but it didn't make him turn around. He sat beside him, observing whatever the other was observing.
They sat side by side for a few minutes, or perhaps hours. Their five senses focused on the scent of rain from the approaching clouds, the cool breeze that made the leaves of the trees rustle, watching the sun disappear. They both thought at the same time.

"Aren't you scared, Kacchan?"

Izuku's voice sounded calm, so Katsuki allowed himself to relax too.

"Who do you think you're talking to, nerd? Someone who pretends to be Japan's greatest hero can't be afraid," Katsuki replied with mock arrogance. He knew it: being number one didn't mean not being afraid, but rather acting despite being afraid. But today he needed to pretend that fear didn't exist, or panic would devour him. Izuku chuckled softly.

"I'm talking about a different kind of fear. I'm terrified of the thought that I could die without having experienced some things that were supossed to be normal."

"We go through a lot more than anyone else our age."

"And those people also experienced a lot of things we didn't."

"Where are you going with this, Izuku?"

"I don't know..." his gaze turns nostalgic, and his cheeks flush. "Sometimes I wish I could have experienced the same things as a normal teenager. Since we decided to go to UA, this is all we do, and I wouldn't change it for anything. But I can't help thinking that I'd like to have gone to an amusement park with my friends, or had a sleepover to watch scary movies and laugh at the people who got scared. It makes me a little sad to think that I could die tomorrow without even having had my first kiss."

Katsuki couldn't hear any of those words make sense when "I could die tomorrow" echoed in his mind. His hands trembled and his breath came in ragged gasps at the mere thought. The pain in his chest was a warning that he needed to change the subject before the walls he'd built his entire life, now made of thin paper, crumbled.

No one would die in battle tomorrow, least of all Izuku. Over his dead body. But he couldn't say that to him.

"Nobody's going to die tomorrow. Not you, not me, not the extras. You'll have your whole damn life ahead of you to act like a fool and get yourself a girlfriend."

For the first time since they'd been on the rooftop, Izuku decided to look directly at Katsuki. His voice, as he affirmed that everything would be alright, was strong and determined, but the trembling of his hands and the slight swaying of his feet indicated the true terror he felt. And that was enough for him to feel less alone.

"Let's get some rest, Kacchan. They're expecting us tomorrow."

-------------

For some weird reason, Izuku feels the urge to tidy his room before going to sleep. Or at least try to. He opens the windows to feel a breeze, packs away all the notebooks and books he'd been studying with for the past few weeks, and decides to put his favorite blanket on his bed—the one his mother gave him when he moved into the dorms, worried her baby would get cold. It was soft and fluffy, perfect for when Izuku needed to feel small.

He was about to go to bed when his door burst open.

"You make me pause one of these movies because you're scared and I'll throw you out the window." Izuku couldn't process what was happening as Katsuki grabbed his laptop and put on a movie, which, judging by the box art, looked like a horror film. He was wearing his pajamas and had placed a tray of popcorn and two caramel apples next to him.

"What's this, Kacchan?"

"Caramel apples are eaten at amusement parks, right? I had more, but I had to give some to that shitty hairy-haired idiot and the electric rat to shut them up. Move aside." Izuku was stunned; everything was happening too fast. What was all this about? Had Katsuki finally lost his mind? He wouldn't blame him; he felt like he'd just lost his own...

"Move over! For this to be a sleepover, we both have to be lying down, and I'm not staying on the floor," Katsuki repeats, forcefully pushing him against the wall. "I'll ignore the All Might face on your blanket."

Finally, Izuku understands: the horror movie, the carnival food, and the pajamas. Katsuki wanted to comfort him; actions, not words, were his way. He genuinely smiles for the first time all day (or maybe all week) and gets comfortable next to Katsuki.

The movie Katsuki had chosen was exciting; nothing more cliché than a zombie invasion where the absent father had to rescue his adorable daughter. It had managed to completely captivate both of them, making them compete to see who could best predict what would happen, getting agitated when the protagonists had to run for their lives, and sighing in frustration every time someone did something clearly stupid.

Neither of them said anything each time they casually found themselves closer and closer. And they didn't make any attempt to move away; the warmth of each other's bodies felt good. It felt safe.
Katsuki won the final bet in the movie when he correctly predicted that the protagonist would die heroically, saving his daughter and a pregnant woman. Izuku couldn't believe the cruelty of such an ending.

"But Kacchan! He can't die! He has to keep his promise!" Izuku cried.

"Life isn't fair, nerd."

Katsuki laughs at his sensitive reaction, but far from mocking him, he hands him some tissues he took from his pocket. Izuku takes them to dry the tears on his cheeks and clear his nose.
"I always knew you were a crybaby, I came prepared."

Izuku realizes that no one will ever know him as well as Katsuki does. And no one will ever make him feel this way. Only he could turn what should be the most desolate night of his life into a night where he laughed more than he had in months. He had chosen exactly the kind of movies he liked and had even brought tissues because he knew he would cry.

"Thanks, Kacchan."

Katsuki knew it wasn't just about the tissues, but he didn't say so to avoid embarrassing him. He loved that about the two of them; they knew each other so well that cheesy words weren't needed to understand the deep meaning of what they felt. Sometimes it got confusing, but that never weakened them.

The next thing they did was play video games; they didn't last more than three rounds. Izuku was winning, and Katsuki couldn't stand it, so what had been a battle on TV turned into a fight in the room. They wrestled in the game, waiting for one of them to back down. All Might's blanket ended up on the floor along with the leftover food.

"Kacchan! You're suffocating me!" Izuku yelled, laughing. Katsuki had decided to do a deadlift on top of Izuku, knowing full well that the freckled boy could lift him if he wanted, but he'd decided to play along. Slowly, Izuku stopped trying to escape, and they fell silent; Katsuki on top of Izuku, both breathing calmly as the atmosphere grew somewhat tense, knowing that the moment they had to say goodbye was drawing ever closer.

The next time they saw each other, it would be in their hero costumes, ready (not really) to go to war and try to fix the chaos that was the society they lived in, even though it wasn't truly their responsibility.

Izuku closed his eyes, deciding to focus on Katsuki's rhythmic breathing and the warmth his body radiated. He felt his heart beating and, without really worrying about the consequences, he brought his hand to his blond hair, seeking to feel its softness. He was surprised when Katsuki accepted his caress, snuggling into Izuku's hand and lifting his head, their eyes meeting.

They didn't understand why, but the atmosphere in the room changed drastically when Katsuki glanced at Izuku's lips for two seconds, his cheeks immediately flushing.

"Can I kiss you, Izuku?"

Izuku had to stifle the desperate cry of "Yes!" that threatened to burst forth. He'd been dreaming of an opportunity like this for years, head over heels in love. He felt his face heat up, probably as red as a tomato, as he tried to make the right decision.

Was it right to let this happen? Why did Katsuki want to kiss him today, of all days? Tomorrow they were going to war, they didn't know if they would return alive, and starting any kind of emotional attachment at this moment was the last thing they needed. Izuku's heart couldn't bear to have tasted even a hint of what a happy life with Kacchan could be, only to lose him.

If he put his feelings aside, Katsuki probably wanted to do it for the same reason he did everything else these past few hours; he was fulfilling Izuku's wishes, so that the next day he could fight without regrets.

"I can't ask that, Kacchan. You've already done so much for me..."

"I'm not doing this for you," Katsuki interrupts. "I'm... doing it for myself. I thought about what you told me a few hours ago on the rooftop. There are so many things we don't experience because we're chasing such a crazy goal as becoming the number one hero. I never minded understanding that there were many things I couldn't allow myself; but you also made me consider the possibility that I could die without ever having been completely honest about my feelings."

Izuku needs a few seconds to process the information. Katsuki's hand moves closer to his cheek, and the touch is so delicate that he wants to cry. He doesn't know whether to cry from emotion or terror.
Is this okay? Even if that first kiss becomes the last?

"For once in our lives, can we indulge ourselves without thinking about the consequences?" he asked uncertainly. He felt so selfish just considering it. But he wanted to do it; it only took him five seconds to decide that, just for that night, it was okay to be selfish.

Without wanting to wait a moment longer, with his hand still in Katsuki's hair, he brought their faces closer until he felt the warmth and softness of the blond's lips. They were both trembling slightly, but at least now it wasn't from terror about what would happen tomorrow, but from nervousness and uncertainty about that area of their relationship they hadn't dared to explore until now.

If before they had thought the warmth of each other's bodies was intoxicating, now that their lips timidly touched, it had become suffocating. Their hands quickly clutched each other's clothes, as if afraid it was all a dream; the position itself was somewhat awkward, Katsuki still lying on top of Izuku, so the blond struggled to separate himself for a few seconds from the freckled boy to sit more comfortably in the middle of the bed and pulled Izuku onto his lap.

Their kisses grew more intense as the spark between them ignited into a wildfire.

"I'm in love with you, Izuku."

"I love you too, Kacchan." They needed nothing more than that. To be honest for once in their lives and let themselves fall into that limbo they both feared so much; deep down, they always knew it, the connection between them was something that could no longer be hidden. But how could they handle something like this when it felt like the weight of an entire country was crashing down on them?

Katsuki's hands gripped Izuku's legs, which were wrapped around his waist, while his partner's hands (because at least for this moment, he would allow himself to fantasize about a life where he had the chance to go out with him) timidly slipped inside his sweatshirt. He felt embarrassed and proud of Izuku's courage in taking the initiative, so he wanted to reciprocate and add his tongue to the equation.
Neither of them had any experience; a french kiss was perhaps too much for a first time, but there wasn't time. There wasn't time...

"Kacchan, what costume are you wearing tomorrow?" Izuku asked, pulling away from the blond for a few seconds. His hands left Katsuki's abdomen and moved to his face, concentrating on memorizing the texture of his skin with his touch and every feature of his face with his gaze.

"The winter one, why?"

"Can I try something?" The blush on his cheeks only made Katsuki's heart race.

"Do whatever you want, Izuku."

Izuku's eyes lit up as he felt the hem of Katsuki's hoodie, waiting for confirmation that he could take it off. The blond boy quickly gave his approval, raising his arms so that his clothes slid off with the freckled boy's help. Izuku gave him a quick kiss on the lips before beginning to shower kisses on his face, moving down his neck to his collarbones, where Katsuki couldn't help but moan as he felt Izuku's tongue on his skin, and a small, sharp pain a second later.

A heavy sigh escaped them both, unable to ignore the sudden movement they felt between their legs. Everything was happening so fast, and they didn't know how to stop.

"Did you just mark me?"

"I've always been curious about how they were done," the green-haired man smiled as he moved closer to his partner's face again. "I like how it looks on your skin. It won't show under your winter suit."

"My turn."

Izuku gasped in surprise when, in less than five seconds, Katsuki ripped off his pajama top and flipped him over on the bed, settling between his legs and guiding his lips directly to Izuku's neck, where he didn't hesitate to use his teeth to leave a few marks that decorated his partner's smooth skin. Thank goodness for Deku's jumpsuit, with its high collar just enough to cover all the marks he planned to make.

"Kacchan! If you keep this up..." Izuku pleaded, his tone of voice revealing how much he was enjoying it.

"I really like you a lot," Katsuki said, glancing up at the freckled boy. His breathing was ragged, his lips swollen from their long kiss, a thin layer of sweat covered his abdomen, and there was a bulge in his pants. He definitely wanted to try that...

He felt his last shred of sanity crumble away. Izuku was too beautiful, and he wished the world would forgive him, but today all he cared about was making the love of his life feel good.

"Shit..." Katsuki groaned as his groin rubbed against the fabric of his clothes. The sensation was too intense to have gone all the way; all he could think about was wanting more, much more. He experimented with his hips, searching for the angle that felt best.

"Ah, Kacchan..." Izuku, also completely out of control, grabs Katsuki's hair and pulls him closer for a passionate kiss. He wraps his legs around his partner's hips, and together they establish a rhythm that brings them closer to climax at an alarming pace. Neither of them wants it to end, not so soon—"Let me be on top."

Katsuki feels like he could come just from hearing Izuku say he wants to ride him. Without hesitating for a second, he grabs Izuku by the waist and uses the impulse to flip them over. Having the love of his life on top of him must be a blessing, better than any wet dream he could have ever had.

The moment Izuku starts moving, their soft moans begin to fill the air. It no longer matters if they're heard, if they're still clothed, or if it's right to do this the day before the fate of the world is decided. All that matters is Kacchan and Izuku, two teenagers experiencing the thrill of their first and only love.

Katsuki's hands caressed the green-haired boy's legs, enjoying the sensation of his muscles tensing as he rocked on top of him. Izuku's hands sought support on the blond's chest, completely ecstatic at having been able to touch that part of Katsuki that attracted him most.

"Keep going, Izuku, don't stop..." Bakugo pleaded, feeling himself reaching his limit. Desperate for some kind of relief, he moved his hands to Izuku's ass, helping him with more forceful and rapid movements.

"Kacchan! Harder!" the green-haired boy begged as he felt Katsuki's hands. Now in the final stretch toward orgasm, they thrust into each other relentlessly and without rhythm, seeking to release the tension they had been accumulating for years. Finally, they reached their climax, Izuku collapsing onto Katsuki, who hugged him while also trying to catch his breath.

After a few minutes, they managed to come down from their cloud.

"I can't believe it was over just from rubbing," Katsuki said. Izuku couldn't help but burst out laughing, making the blond laugh too. The green-haired boy's laughter sounded so angelic; Bakugo missed the way that sound could light up even the darkest heart, including his own.

"We could use a bath," Izuku smiled, "but first, I want some more cuddles. It's not every day you get cuddles from Kacchan."

Five more minutes passed before they decided their clothes felt disgusting (after all, they hadn't taken them off), so, careful not to be discovered, they showered in the communal bathrooms. Once dressed and clean, Izuku headed back to his room, followed by Katsuki, who hadn't said a word the whole way but had a relaxed expression.

"Can I ask just one more thing, Kacchan?"

"Anything you want."

"Can we sleep together tonight?"

That's how they ended up snuggled up in Izuku's bed, which they had to put back together because they'd left it a mess. Katsuki gently stroked Izuku's cheeks, trying to memorize the texture of his skin and the coconut scent of the soap he used.

Together, clinging to each other, under the warmth of Izuku's bed, they both realized what would happen when they woke up the next day. The adrenaline of experiencing their first love vanished, their breaths became ragged, their bodies trembled, and Izuku's eyes filled with tears; they knew this would happen, they couldn't let go.

“Izuku, listen to me.”

“I don’t wanna die, Kacchan. I don’t want anyone to die.”

“We can’t control that.”

“But we are héroes! We are supposed to save everyone. I am supposed to save everyone…”

“Don’t you dare talking only about you. We are togheter in this. You, me, the extras, and every fucking hero will be there. Don´t you ever lift that responsability on your own again.”

"I'm terrified of the possibility that I might have to give my life for everyone's sake. I don't want to die."

"You won't die." Katsuki cups Izuku's face in his hands and wipes away his tears so he can look him straight in the eyes. "We won't die. Promise me that no matter what happens, you'll come back to me safely and we can continue this. I don't want to have to say goodbye to you now that we're finally together."

<<< Beast Jeanist feels paralyzed when he senses his student's intentions.

"Ba..."

"Take good care of everyone," Dynamight replies. "We still have a battle to win. Rigth, Izuku? Can I still catch up to you?">>>

Izuku had to swallow the sobs that threatened to escape in order to answer.

"You promise me too," pleaded.

<<< He surveyed the scene, trying to assess the extent of the damage and who was truly fit to fight. Her friends, teachers, everyone was defeated. What did he do now? He had to come up with a plan that would at least lure Shigaraki away so they would no longer be in danger... Where was Dynamight?

His heart raced as he searched for Kacchan; he knew he had to be in this area. He felt his heart shatter and his entire body go numb when he finally found him. He was on the ground, covered in blood, and even though he was some distance away, he noticed he was pale. Could he...?

We had a promise! >>>

"I would return from the dead to keep our promise."

<<< Suddenly, he feels warmth returning to his body; something is happening. Some kind of energy makes him see directly above the rooftop of a building, where he finds Dynamight making his triumphant return. Their eyes meet, and even though they are far apart, Izuku understands what Katsuki meant. He really had kept his promise...

"I told you I would return, Izuku. We will win together." >>>
