Plaything, he's trying to be in a relationship with him because he doesn't want his fame to be ruined

oh but does having jihoon as his plaything got to do with his fame? i’m kinda mad now #－.－)

Because the one of the cast members(camera man) took a foto of yoojin and yohan(?) while they had sxx. The camera man had a one night Stand with yohan, he fell in love with him.
That's why he threatened yoojin to start a relationship with Jihoon, because yohan(?) would then stop pursuing jihoon( he stays away from people in relationships), so the camera man can shoot his shot.
But if yoojin doesn't stop the other two becoming closer, the Foto will then be published online and thus ruin his perfect image.

Hope you could understand it

ohhhh! i get it now. thank you for the explaination! (≧∀≦)

I feel like Yoojin is already starting to have feelings for Jihoon, but he hasn’t figured that out yet and doesn’t want to get too serious with Jihoon since he has trust issues (you will find out why very soon). I think they will eventually date each other, and then the conflict would be that Jihoon would find out that that the camera man only ordered Yoojin to do date him so that his perfect image won’t be ruined. :/

Yeah pretty much.
I think jihoon started getting feelings in season 1 then over heard mcs manager saying stuff like he should use all the connections he can for personal gain and then he got bitter jumping to conclusions about mcs character thinking that mc was trying to use him
