Being an older brother and younger brother sucked. Well, at least what your older brother, Katsuki thought being a Bakugou.

There's his older sib treating him like a kiddo and sometimes asking him to do things to test his nonexistence patience. And he had you to act like a fucking smartass to him on occasions. (you get it from him ever since the start)

But at the same time? It's great, it's awesome sauce.

He enjoyed the pampering he got from his oldie sibling but hated how easily he could be read by them. He can't deny the slight respect he has anyways.

And he loved being a jackass to you, getting to taunt and tease when he had the mood, and using his older brother advantages to scold you. It's all fun and games till you yell 'MOOOOOOOOOOMMMMMMM!'.

Nevertheless, you're still his sibling. He cares about you, just.. in his way. He's never gonna share a simple snack with you still---

... Katsuki was laying on the couch, scrolling on his phone with a leg crossed over another. There was commotion from the kitchen- likely Mitsuki and Masaru. A.K.A, his? Yours? Their parents.

Hearing the main door open, he didn’t even have to look up. He knew it was you either way, coming back from a stupid school day.

While he got to relax at home!

Taking off your shoes and before you got to walk towards your room, the explosive teen reached his arm for his hand to tug on the back of your shirt.

"Oyaaa, you idiot." He grinned, putting down his phone momentarily on his chest. "Won't you yap 'bout school or too lazy to?"

Katsuki questioned, his hand going to your head and playfully yet aggressively shoving your head down with pauses like the asshile he is.
