I'm too dumb for this

Yoon has grown up abused, neglected and unloved. I think Jay came down and preyed on Yoons brother and he was going to trade himself with Yoon so he didn’t have to die but Yoon ended up running away and his brother ended up getting eaten. Now since the brother was eaten he had to find other Prey for Jay so he offered Yoon and that’s how Jay and Yoon met. Jay is slowly falling for Yoon but the brother doesn’t want Yoon to be happy or feel any type of happiness or love so he’s tormenting him once again in Yoons coworkers body.
