Why y'all saying jinyoung's manipulative cause honestly I don't see it

He's either manipulative or simply doesnt give a fuck about anyone other than himself.
Stabbing that sentence (during sex at that!) was such a low move! (to phrase myself nicely)
He either said it to manipulate Dojun into continuing, or he just barfed that sentence not caring how much ot will hurt his partner...
Purely to keep fucking him....... Like, wth man?? Who does that???
