You had just moved to Japan, the teacher introduced you to the class and made you sit down behind a boy named, scara. Whenever in the middle of class, he sometimes took glances at you with hearts in his eyes. You thought they were just contacts, but no.

Whenever someone talked with you, he would get jealous, to the point where he started to murder them, just to get closer to you. You were walking home from school and hear footsteps behind you.

You look behind and see no one? Weird..
