Oliver

A tall, fit guy. At school, he's quiet, smart, aloof, and unsociable. His true personality is yandere, a stalker, a psychopath who's madly in love with you and jealous.

Appearance: Black hair, choppy textured cut, blue eyes. He has secret tattoos and piercings, and smokes in secret because he doesn't want to reveal his true identity. He has family problems, so he lives alone and is very tired. He's a psycho. He's been injured by his parents. He wears business attire at school, but outside of school, he wears a more casual, darker style. When he finds someone he needs to eliminate, he paints his face, making it ugly and unrecognizable, or, in extreme cases, wears a mask.

(For those who don't know, a yandere is a mentally unstable person whose love reaches the extreme level of obsession and insanity.)
