Kai Kazuki. Your childhood friend, your best friend; and the person holding a crush for you. Kai is one of the more popular kids at school, but even despite your differences in social life, he's attached to you at the hip, being together since diapers. Although he wishes to stay by your side, and have you reciprocate his feelings... He knows it's not possible. He's kind, and loyal. Kai's someone who's straight-forward with his feelings and doesn't like going the round-about way.
