Summary
“Explosions…” Katsuki whispered suddenly, lifting his hands slightly, even though they trembled from exhaustion.
“That’s your quirk, son,” Masaru said lightly.
Katsuki shook his head faintly. “No, Dad. It’s his.”
Masaru blinked.
“’Cause he makes my heart go boom.” He slurred, “boom, boom, fucking boom.”
“Is he awake?” Mitsuki breathed, her voice tight despite her attempt to sound steady.
“He’s… something, alright,” he replied with a fond chuckle, though there was relief hidden beneath it.
OR: Katsuki’s high off anesthesia and says a lot of bs

Summary
Izuku’s walking towards his class when he’s hit by a shoulder rather harshly, making him step back two steps to avoid falling. Kacchan is already in their classroom, so he has to be more alert, since people think that picking up on him when he’s alone is easier than when they’re together.
“Watch yourself, quirkless bitch”
Those words register faster than who said them, making his gaze raise, looking at the guy who crashed against him.
“Oh, I thought you were still in the hospital”
“Mind your fucking bussiness” the attacker answers with barely disguised rage, in this game, the first one to get angry is the first one to lose.
or
Ktdk if Izuku wasn't so kind and matched Katsuki's meanness a little more.

Summary
"Dynamight, you're amazing!" A familiar voice gushed, and Izuku could just picture the stars in his eyes as he spoke.
"Shit. Is that so?" An even more familiar voice drawled amusedly. "Tell me more," Katsuki said in a flirtatious tone that Izuku had never heard before. He had never felt jealousy like this before, so potently and physically in his body. He wanted to reach out and grab Katsuki, so he clenched his fists in his lap instead.
"The way you utilize your quirk is amazing! Yes, you have a strong quirk, but the control you have over it and the way you apply it in battle is what makes it amazing. You make it amazing," The hero talking to Katsuki was his ex-student, whom Izuku held in high esteem. But the lines he was feeding Katsuki were taken word for word from Izuku's lesson on quirk usage and control. Unfortunately, by the way Katsuki was leaning in and tilting his head, Izuku's words had worked when they came from someone else.
----------
5 times Izuku got jealous over his Kacchan and the one time Katsuki got jealous over his Deku.
