Chapter Text
They fell into a routine that was both domestic and thrilling.
Monday through Friday, they were the perfect fake couple at school. Holding hands in the halls. Eating lunch together. Katsuki walking Izuku to class, his arm around Izuku's waist, possessive and public. They kissed where people could see– deep, claiming kisses that left Izuku breathless and blushing.
The school buzzed with gossip. Bakugo and Midoriya? Since when? Are they serious? Did you see them in the hallway?
Shindo watched them with narrowed eyes, his jealousy obvious. He tried to talk to Izuku once, cornering him by the lockers, but Katsuki appeared before he could say much, wrapping an arm around Izuku's shoulders, glaring at Shindo with those crimson eyes.
"Problem?" Katsuki asked, his voice dangerous.
"Just catching up with an old friend," Shindo said, his smile tight.
"We're late for lunch," Katsuki said, steering Izuku away. "See you around, Shindo."
Afterward, in the empty classroom where they'd hidden to make out, Katsuki pinned Izuku against the wall and kissed him until Izuku's knees went weak.
"You're mine," Katsuki growled against his mouth. "Not his. Mine."
"Yours," Izuku agreed, breathless. "Only yours."
They didn't define what they were. Didn't label it. But the fake relationship was feeling more real every day.
Tuesday and Thursday evenings were for ballet. Katsuki had improved dramatically– he could now execute a perfect grand jeté, his leaps higher and more controlled than ever. Coach Aizawa was impressed, nodding approval at games, keeping him in the starting lineup.
"You've got natural talent," Izuku told him one evening, as Katsuki executed a complicated combination. "If you'd started younger, you could have been a professional."
"I don't want to be a professional dancer," Katsuki said, coming to stand behind Izuku at the barre. "I just want to be good enough to keep my scholarship."
"You're more than good enough," Izuku said, meeting his eyes in the mirror.
Katsuki kissed the back of his neck, making Izuku shiver. "Only because I have a good teacher."
Saturday afternoons were for sex.
They'd moved from the basement to Izuku's bedroom, to Katsuki's car, to empty classrooms after hours. They couldn't keep their hands off each other– every lesson turned into making out, every making out session turned into more.
Katsuki taught Izuku everything. How to ride him, Izuku's hips rolling in a way that combined his ballet training with pure instinct, the angle perfect, hitting all the right spots. How to take him from behind, Katsuki gripping Izuku's hips, pounding into him while Izuku screamed into the pillows. How to face each other, intimate and intense, kissing as they moved together, coming apart in each other's arms.
They learned each other's bodies. Katsuki learned that Izuku loved being praised– loved being told he was beautiful, good, perfect. Izuku learned that Katsuki loved being touched– loved having his hair played with, his back scratched, his face held while they kissed.
And they learned positions. So many positions.
Izuku on his back, legs over Katsuki's shoulders, taking him deep. Izuku on top, riding Katsuki's cock while Katsuki thrust up into him. Spooning, Katsuki entering him from behind, slow and lazy, coming inside him and staying there, connected, falling asleep still joined.
They were in love. They didn't say it, but they knew it. Every touch, every kiss, every whispered mine in the dark confirmed it.
But neither of them had the courage to speak the words aloud.
March arrived, and with it, prom season.
The theme was "Starry Night," and the gym was being transformed into a galaxy of blue and silver. Tickets went on sale. Dresses were bought. Tuxedos rented.
"Are we going?" Izuku asked one Saturday, lying in Katsuki's arms, his body still trembling from their third round of the afternoon.
"Do you want to go?" Katsuki countered.
"It was part of the deal," Izuku said quietly. "Fake dating. Prom. Make Shindo jealous."
"Fuck the deal," Katsuki said, rolling them so he was looking down at Izuku. "Do you want to go? With me?"
Izuku's eyes were huge, vulnerable. "I want to go with you," he whispered. "Not because of the deal. Because... because I want to dance with you. Show you off. Be your date."
"Then we're going," Katsuki said, kissing him softly. "And Izuku?"
"Yeah?"
"I'm not pretending anymore. When we're there, when we're dancing... that's real. Okay? Whatever happens, whatever people think... I want it to be real."
Izuku's eyes filled with tears. "Real," he repeated. "Okay. Real."
They bought tickets. Katsuki rented a tux– black with green accents, matching Izuku's eyes. Izuku bought a suit in deep emerald, fitted and beautiful, showing off his dancer's body.
The week before prom, everything felt perfect. Katsuki's team had made playoffs. Izuku's showcase had gone brilliantly– Juilliard scouts had approached him afterward, talking about scholarships. They were both going to college, both pursuing their dreams, and they were doing it together.
Or so they thought.
Prom night arrived with perfect weather, warm and clear, the sky already studded with stars.
Katsuki picked Izuku up in his car, wearing his tux, his hair actually styled for once instead of its usual wild spikes. He brought boutonnieres– one for Izuku's tux, one for his own, matching orange roses.
"You look beautiful," Katsuki said when Izuku opened the door, and meant it.
Izuku did look beautiful. The emerald suit fit him perfectly, his hair styled to show off his freckles, his eyes bright with excitement.
"You too," Izuku said, his voice soft. "You look... you look like someone I want to be with forever."
They didn't say I love you. They still couldn't. But they kissed at the door, soft and sweet, and drove to prom holding hands.
The gym was transformed. Blue lights and silver stars hung from the ceiling, creating the illusion of dancing under the night sky. The music was loud, the energy high, everyone dressed in their finest.
Katsuki and Izuku entered together, and the crowd noticed. Whispers started– the star athlete and the dancer, the unlikely couple, holding hands and not caring who saw.
They danced. Slow songs and fast songs, Katsuki surprisingly light on his feet thanks to his ballet training, Izuku graceful and fluid. They laughed, they kissed, they stole champagne from the teachers' table and got tipsy together.
It was perfect. It was everything they'd both wanted.
And then it all fell apart.
Izuku went to the bathroom, leaving Katsuki talking to his teammates. He was washing his hands when the door opened, and Shindo walked in.
"Izuku," Shindo said, his voice smooth, his eyes sharp. "You look good."
"Shindo," Izuku said, keeping his voice neutral. "What do you want?"
"I want to talk. About us. About what we had."
"We had nothing," Izuku said, turning to leave. "You made that clear when you dumped me."
Shindo grabbed his arm, spinning him around. "I made a mistake. I know that now. Seeing you with Bakugo... it made me realize what I lost. You're different now. Confident. Sexy. I want you back."
"I don't want you back," Izuku said, trying to pull away. "Let go of me."
"Just give me a chance," Shindo said, his grip tightening. "One kiss. For old times' sake. If you don't feel anything, I'll let you go."
"Shindo, stop–"
Shindo kissed him. Hard. Forceful. Not like Katsuki's kisses– this was demanding, invasive, unwanted. Izuku struggled, pushing against his chest, but Shindo was stronger, holding him in place.
The bathroom door opened. Katsuki walked in, looking for Izuku, and froze.
He saw them. Shindo and Izuku, kissing. Izuku not pulling away– or rather, pulling away but unable to escape. But Katsuki didn't see the struggle. He only saw the kiss.
His face went blank. Empty. The way it did before he exploded.
"Izuku," he said, his voice terrifyingly calm.
Shindo let go, smirking. "Hey, Bakugo. Just catching up with my ex."
"Kacchan," Izuku said, his voice shaking. "It's not– It’s not what it looks like–"
"Save it," Katsuki said, turning away. "I should have known. Should have known it was too good to be true. Have fun with your ex, Midoriya."
He walked out. Izuku ran after him, leaving Shindo laughing behind them.
"Kacchan, wait!" Izuku chased him through the gym, out the doors, into the parking lot. "Please, listen to me–"
Katsuki whirled around, his eyes blazing, his hands sparking with suppressed explosions. "Don't. Don't you dare. I saw you, Izuku. I saw you kissing him."
"He kissed me!" Izuku cried, tears streaming down his face. "I didn't want it! I was trying to get away–"
"Looked like you were enjoying it to me," Katsuki snarled, the words cutting deep. "All this time, I thought... I thought we were real. But this was always about him, wasn't it? Making him jealous. Making him want you back. Well, congratulations. It worked."
"No," Izuku sobbed. "No, that's not– Kacchan, I love you. I love you. Not him. Never him. I love you–"
"Don't lie to me!" Katsuki shouted, his voice breaking. "Don't fucking lie to me, Izuku! You made a deal. Ballet lessons for sex lessons. Fake dating to make your ex jealous. I was just... I was just convenient. Just a tool. Isn't that right?"
"No!" Izuku screamed, his own emotions breaking through. "That's not true! Maybe that was the deal at first, but everything changed! You changed! I changed! I fell in love with you, you stupid, stubborn, beautiful idiot! I love you! I've loved you for months! And I'm sorry about Shindo, I'm sorry you saw that, but I never wanted him! I only ever wanted you!"
Katsuki stared at him, his anger faltering, replaced by something desperate and hopeful. "You... you love me?"
"Yes," Izuku sobbed, collapsing to his knees in the parking lot, his tux ruined, his heart broken. "Yes, I love you. I love you so much it hurts. Please, Kacchan. Please believe me."
Katsuki was silent for a long time. Then he moved, crouching down, taking Izuku's face in his hands.
"I believe you," he said quietly. "I'm sorry. I saw red. I didn't think. I just... the thought of losing you. Of you choosing him. It made me crazy."
"I would never choose him," Izuku whispered. "Never. You're the only one. The only one I've ever wanted."
Katsuki kissed him then, in the parking lot, under the stars. A kiss of apology and forgiveness and love so big it couldn't be contained.
"I love you too," Katsuki said when they broke apart. "I have for so long. I was just... I was scared to say it. Scared you didn't feel the same."
"I do," Izuku said, laughing through his tears. "I do, I do, I do."
They held each other in the parking lot, prom going on without them, the world reduced to just the two of them and their confessed love.
But they weren't done.
"Come with me," Katsuki said, standing up, pulling Izuku with him.
"Where?"
"Somewhere private. Somewhere ours."
He led Izuku across the parking lot, past the school, to the football field behind the gym. It was empty, dark, the goalposts silhouetted against the starry sky. The grass was soft, recently mowed, smelling of green and earth.
"Here," Katsuki said, his voice rough with emotion. "I want our first real everything to be here. First real kiss as people who love each other. First time making love, not just having sex. Here. Under the stars."
Izuku's breath caught. "Here? Now?"
"Unless you don't want–"
"I want," Izuku said immediately. "I want everything. With you. Always."
They laid down together on the grass, the stars wheeling overhead, the sounds of prom distant and muffled. Katsuki undressed Izuku slowly, carefully, treating him like something precious. Izuku did the same, revealing Katsuki's body in the moonlight.
"I love you," Katsuki whispered, kissing Izuku's chest, his stomach, his hips. "I love every part of you."
"I love you too," Izuku gasped, arching as Katsuki's mouth found his cunt, licking him open, making him wet and ready.
When Katsuki entered him, it was different from all the times before. Slower, deeper, more intimate. They moved together, staring into each other's eyes, their breath mingling, their hearts beating in sync.
"I've got you," Katsuki whispered, thrusting gently. "I've got you, Izuku. I'm never letting go."
"Don't let go," Izuku begged, his legs wrapped around Katsuki's waist. "Stay with me. Forever."
"Forever," Katsuki promised.
They made love on the football field, under the stars, and when they came together– Katsuki filling Izuku with his seed, Izuku clenching around him, crying out his name– it was with the knowledge that this was real, this was true, this was love.
Afterward, they lay together, tangled in each other and their discarded clothes, watching the stars.
"Prom king and queen announcement is probably happening," Izuku murmured, his head on Katsuki's chest.
"Don't care," Katsuki said, stroking his hair.
"Me neither."
They stayed there for hours, talking about the future. College, careers, where they would live, what they would become.
"We're young," Katsuki said. "We have time. But I want it all. With you."
"Me too," Izuku agreed, smiling. "Everything. With you."
The stars sighed overhead, indifferent and eternal, witnesses to a love that had started with hatred and transformed into something unbreakable.
Katsuki Bakugo and Izuku Midoriya. The jock and the ballerina. The bully and the victim. The alpha and the omega.
They had found each other. And they would never let go.
