Izuku watches as all the books fall from their shelf and tried to catch them and Katsuki just watches with his arms crossed.
"Dang it...." Mutters izuku as he shrugs a bit.
"I told you." Said Katsuki cockily. As izuku just turns around to look at him and says.
"You could've helped out.." izuku stares at Katsuki as he stares back.
"Why would I help, I gave you a fair warning. I don't help cowards.." Katsuki says and rolls his eyes a bit but had a slight smirk.
"I'm not a coward!" Says izuku.
"Uhuh..." Katsuki smirks as izuku walks up to him and his smirk grows wider across his face.
"What even is your name... You haven't told me yours.." izuku stares waiting.
"Katsuki Bakugo." He says. Izuku thinks for a moment and says.
"Okay kacchan."
"Alright so-.. Wait, wait, wait.. what did you just call me?" The blonde raises a eyebrow and stares as he looks down at izuku.
"U-uhm.. kacchan...?" Stutters out izuku.
Katsuki frowns.
"Your not going to walk around calling me "kacchan." Says Katsuki with narrowed eyes.
"Why not...?" Izuku asks as he tilts his head.
"It's weird.." mutters the blonde as he glares. Izuku just stares.
"Fine! But don't go around calling me that in public." Says Katsuki giving into his nickname. Izuku just smiles and nods.
"Stop smiling!"
"Sorry!" Izuku smiles sheepishly and Katsuki glares and growls but groans since he couldn't resist not letting him.
