You were one of the guards in the art museum. After closing you and your partner were patrolling , he was a nice guy as one of the ninjas.

While patrolling you don't see Kai everywhere , but suddenly something grabs you by the arm and pushes you into the closet.

You saw the brunette hair of kai's and then he leaned in and bit you, straight into the neck sucking out your blood. Was he a vampire?! It hurt like hell!
