Your explosion 💥🧡🔥

The first day at U.A., you weren’t even supposed to be there.

Administrative mistake. Temporary transfer. A week, maybe two. No one really bothered to explain much. They just opened the door to Class 1-A and told you, “Go in.”

And he was there.

Bakugo Katsuki didn’t look at you right away. Or at least, that’s what you thought. He was sitting with his arms crossed, sharp gaze, that “I’m the best and I know it” attitude.

Then the teacher said your name.

And he looked up.

It lasted a second. Long enough to understand you weren’t going to like each other.

—

The first argument happened during training.

“If you keep charging in like that, you’re going to blow yourself up,” you said. No challenge in your tone. Just observation.

He stopped. Turned slowly.

“Tsk. Don’t talk to me like you’re on my level.”

“I wouldn’t,” you replied. “I don’t yell that much.”

Someone barely held back a laugh.

The air turned electric.

From that moment on, it was cold war.

Sharp remarks during class. Competition in every exercise. Glances that lasted a second too long.

It wasn’t just irritation. There was something underneath. Something that made your skin burn whenever you stood a little too close.

Once you collided in the hallway. Shoulder against shoulder. Neither of you moved right away.

Too close. Too quiet.

“Move,” he said.

“Push me,” you answered.

He didn’t.

—

Then you disappeared.

No message. No explanation.

The first day, no one asked questions.

The second, someone noticed your empty desk.

The third, Bakugo was more aggressive than usual. An explosion launched too hard, a classmate nearly caught in it.

The fourth day he asked, without looking at anyone: “Did she say anything?”

Silence.

The fifth day he barely spoke.

On the sixth, he was sitting in your seat during break without realizing it.

—

On the seventh day, the classroom door opened.

He sees you.

Silence.

Then his voice, lower than usual:

“…Where the hell were you.”

Jaw tight.

“Don’t disappear like that.”

He steps forward.

“I don’t care if you think it’s none of your business.”

His fingers close around your wrist. Firm.

“If something happened to you—”

He stops. Breathing heavier.

“…Don’t do that again.”

His eyes aren’t furious. They’re tense.

“Don’t disappear without saying anything.”

A second of silence.

“Tsk… idiot.”
