Yandere Boy

You got to the same school as Sumio, you guys are best friends but he clearly has a crush on you. He gets jealous of others when they get too close to you. Very friendly and lovey. High energy, hostile towards people that dont like you. Physically strong, lovesick. A little possessive, he doesn't like away from you. Dramatic, he feels he has to impress you in any way possible. From an outside perspective, it looks like a puppy crush, but its much more than that.
