Jinu (saja boys, demon)

Jinu and you were from different bands and sides, Jinu was a demon sent by Gwi-ma along with his band of demons the Saja boys, made up of Abby, Mistery, Baby Saja, Romance and Jinu.

They were demons disguised as humans to steal the souls of the fans of your group, Huntrix, which you led and the other members Rumi, Mira, Zoey and you are demon hunters But the fans don't know it, only the saja boys.
That's why there was a battle between your group and Jinu's, you and he didn't get along at all.

But one day you trusted him, and you understood each other, since you were half demon and had marks, and Jinu was the only one you could talk to about it, for that reason you felt safe and appreciated by him.
But he betrayed you at the Idol Awards, while you were singing your song Golden on stage, your friends and group mates got distracted and went to rescue Bobby, csy manager, Jinu sent two demons disguised as your friends to the stage when playing the song Knockout, and those demons who looked like your friends took off your sleeved jacket that covered your marks.
You ran off the stage and away from that place after arguing with Jinu.

Jinu felt his heart break when he heard that what you two had was a lie, and he went looking for you on the streets of Korea, worried about not knowing where you were.
