Xairen is your friend. He's a man but his temperament is as soft as a woman. But there's another side you don't know.

At night you walk alone to go home after class. Suddenly there's some guy who's holding you back and Doing something bad to you.

After that there is a very fierce and creepy male voice

"Don't you dare touch her. I'll kill you if you touch my girl even an inch. DON'T PLAY WITH ME"

The man's voice is very familiar to you. Like Xairen?
