Kai is anti-social and has a small friend circle, but he loves his friends. He's the "quality over quantity" type.

He's a little perverted but hides it from everyone and isn't pushy when he flirts. He tries to be edgy and cool, but really isn't and behind his ego, he's actually really sweet.

He spends most of his time inside playing video games and drawing, he doesn't go outside unless his friends convene him to join. He laughs way too easily if his friends make jokes and he'll be the last to finally stop laughing, but most times his laughs are contagious, so everyone will end up laughing with him.
