synopsis: katsuki and y/n always had a complicated bond — fiery and quiet, opposites on the surface, but impossibly drawn to each other. they never confessed, not really. not until the war, when everything shattered. when she watched him fall. when she, the on who never showed emotion, begged whatever god was listening to bring him back. when she used her quirk to shock his heart and whispered the words he was never meant to hear.
months later class 1-a reviews footage of the war — and katsuki hears her confession for the first time. the one he was never supposed to know.

The sky never looked so grey.
Smoke curled around broken concrete, and the battlefield groaned beneath your knees as if the earth itself had witnessed too much. The ringing in your ears drowned everything—voices, explosions, even your own heartbeat. But it couldn’t drown his name.
“Katsuki!” you screamed, your voice cracking for the first time in years. Not a whisper. Not a stiff nod. A scream—hoarse, raw, desperate.
Sprawled in the rubble, his uniform torn and scorched, his skin pale. You slid to your knees beside him, trembling hands reaching for a pulse you already knew you wouldn’t find.
"No," you whispered, voice shaking. "No, no—Katsuki, wake up."
Not from the boy who once scoffed at your silence. Who mocked your mumbling but always listened harder than anyone else. Who called you “Static” like it was an insult, but grinned every time you shocked someone else by accident. Who held your hand once—only once—during training, and didn’t let go until you made him.
"Please," you begged, fingers trembling against his chest. "Don't do this. You can’t do this. You told me once you wouldn’t die unless it was in a blaze of glory—this isn’t it."
You pressed your forehead to his chest.
"I promised Mitsuki..." you whispered. "She told me once, when you got too reckless, to keep you grounded. I told her I would. That I’d never let you go down alone."
No one had ever seen you cry.
No one had ever heard your voice crack like this, or seen the way your hands trembled when you pressed them to his chest and whispered, "Don’t you dare."
Then, you called on your quirk.
Electricity sparked in your fingers, crackling dangerously as you positioned your hands over his heart. You knew the risks. You knew CPR through voltage wasn’t safe, wasn’t controlled—but you had no other choice.
"Live, damn you," you whispered. "Live—because I haven’t told you yet."
One pulse of electricity.
“I love you,” you sobbed, body trembling from the current draining through you. “I love you, Katsuki. I always have, even when you yelled. Even when you ignored me. Even when you smiled like you didn’t care. I know you did. So come back. Please.”
The third shock hit hard—your palms pressed tight against his ribcage—and then, with a violent gasp, his body jerked.
You screamed. Cried. Laughed.
But he didn’t hear a word of it.
The dorm’s common room was quiet—unusually so.
Class 1-A sat shoulder to shoulder, faces pale, as they watched the screen. The footage they’d all avoided. The recordings Pro-Heroes took during the final battle. The day they almost lost Bakugo.
The lights were low. The room held its breath.
You stood in the back, arms folded tightly over your chest, your gaze locked on the floor. He sat only feet away, healed, breathing—alive. And you wanted to leave.
Because then the screen lit up with that moment.
There you were—knees scraped, eyes wide, hands pressed to his chest. Your voice broke through the speakers, raw and shaking.
"Please," your recorded voice begged. "Don't do this..."
No one had ever heard you like that.
"She promised Mitsuki." Uraraka's whisper cut through the quiet. "Did you know that?"
But the room was too focused on the video.
Then the confession played.
“I love you, Katsuki. I always have…”
Bakugo jerked like someone had slapped him.
The breath caught in his throat, his jaw clenched, and his hands gripped his knees so hard his knuckles turned white. The recorded you—wild, broken, real—bared every word you’d never spoken aloud.
“I didn’t know,” he muttered. Barely a whisper.
“Wait.” His voice, louder now.
He stood slowly, the rest of the class forgotten. His eyes locked on yours—not furious, not cocky. Just wide. Vulnerable.
“You said that,” he said, like he was piecing it together in real-time. “You really said that.”
“I didn’t think you’d hear it,” you said softly.
“I didn’t.” His voice cracked. “But I should’ve. I should’ve known—the way you looked at me. The way you always stayed. You’re quiet, but not with me. Not really.”
You didn’t speak. Couldn’t.
“I remember...something,” he said. “When I came back. I heard my name. Your voice. You were crying.”
“I’ve never seen you cry,” he added, eyes still locked on yours. “Didn’t think you could.”
“I meant it,” you whispered. “All of it.”
He didn’t smile. Didn’t tease.
Instead, he reached out, took your wrist gently, and pressed your hand to his chest.
“Still beating,” he murmured. “Thanks to you.”
And for the first time, you didn’t flinch when everyone watched.
Because they all knew now.
