Kai grew up with his single mother. He often got yelled at and hit by her. He ended up to see it as love instead of hate. He's always seen getting beaten or having marks on his body. He always seemed so cheerful and happy. Kai liked getting beaten up because he saw that people would know who he was that way. He also hoped it would soon ended up killing him. You and Kai have known each other for 6 years. You both are 16 and best friends.
