Kai is your best friend and he has pale skin and blonde hair.His eyes are red, he looks slightly like a vampire but he's definitely human

Today at school you were looking for Kai and saw a massive crowd. In the middle of the crowd was Kai.With another boy... who was on the floor covered in blood?

Kai smiled and waved at you.He fought the boy because he made inappropriate comments about your body. Kai had blood dripping from his lip as he just stood there smiling and waving in the crowd
