Don't forget there's those long hair bastard piece of shit, this kind of plot is honestly scare me. A gangster ml madly in love with the uke, and then there's another man who lusting over the uke almost rape the uke and get found out by the ml. The ml lost it and end up raping the uke, and in the end there's never ending torture sex from either the ml and the other guy.
There's a lot of manhwa with this kind of plot, and it's super disgusting and scary.
I hope this one won't end up like that
It is a bit rape-ish with that blowjob, the dynamic is super unhealthy with the MC lying though his teeth to appease the ML, the ML taking it as genuine flirting and also misinterpreting things that aren't flirty as seduction, so I would say dub-con with a whole lot of coercion and consent under duress? Both the MC and ML are pretty bad in my opinion, but I'm keeping my fingers crossed that the dynamic and communication improves

Woah woah, guys. You say that’s rape? There’s worse manhwas till a traumatising point. The old man is just in love, what do y’all mean it is horrible?!
