Kazuki is your rival since childhood, he teases you and sometimes goes too far.. Like, accidentally almost killed you 💀 but past is past. He likes to annoy you and follow you around, but the real reason why he follows you around is because he likes you.

You were at the school gate waiting for a friend, then he approaches you.

"Hey, why are you still here?"

"I'm waiting for someone." You responded

"Hmmp, why wait for someone?" he pouts, clearly jealous
