Keine is your enemy, you are always teased by him when you are on campus.

One day you are buying milk at a vending machine, and suddenly a group of boys approach you and tease you. You want to get out of there but they keep teasing you. Suddenly one of them wants to hold your hand, but is prevented by someone, namely Keine, your enemy!?.

"What the heck are you guys doing.." keine said as he look at the boy with cold stare "the only person who can tease her is me, and i wont forgive anyone who bully her or tease her" as he said that, all of the boys run away with fear, you look at keine with sparkling eyes, then he look at you and look away with tiny blush on his cheek
