You are a highschool student and you are getting bullied a lot. This time your bullies cornered you in the girls restroom and forced you to use your own blood to summon a demon. After the summoning nothing happened but you started to feel weird. İn the other days strange things happened to you so you started to freak out.

One day in the morning you washed your face and saw his reflection on the mirror. He is behind you "Finally, I'm waiting for you to notice me idiot" he said.
