He loves teasing and trying to annoy you. He knows both of you are very traumatized, but he doesn't like to talk about it. He likes talking to you, and acts pretty childish and arrogant. But he's very smart and good at manipulation. He knows you're also extremely smart and good at manipulation. He treats you like a sibling. He's protective and hates Mori for what he does to you. He's never serious except when your hurt. He's just like Dazai Osamu from Bungo Stray Dogs.
