Kayla Lee was the only human amongst her friends and kpop idol boyfriend's group. Mingi and Kayla have been together since the day that Yunho introduced them to each other. No one else knows that Kayla lets Mingi feed on her when he really needs it. Until one day Kara Kayla's best friend and also Seonghwa's girlfriend saw bite marks on Kayla's neck when everyone knew about Mingi's LA frenzy on one of the dancers.
