Well it depends on from what point you view it.
In both stories we have poor, hardworking, innocent mc that need money asap.
In this stories older guy gets close to him for sexual reasons, but from mc perspective it's a consensual relationship so when his needs and opinions started being ignored, he was shocked to be in "sugar baby" position because he wasn't really aware about this kind of dynamic between them.
In Jinx mc knows from the start that he's in unbalanced paid deal, that he consented to be in for money he needed (it doesn't mean it was a good thing for him, since it wasn't an enthusiastic consent). That in itself changes the dynamic that he has with ml, since he is aware of what type of person ml really is.
From what I had seen so far ahjuicy doesn't seem to have any trauma that would explain why he become like that, and why he behave
like that. Where ml from Jinx had that explained in his backstory, and never imprisoned Kim Dan because of his insecurities. So from my perspective Ahjuicy is a worst seme than Joo Jaekyung, based on what we had seen so far.

Not gonna lie the signs were there, I knew he was a red flag and didn't believed the comments like "no he's not so bad, it's just translation problems..."
Welp now Jinx doesn't seem so bad in the comparison hmmm?
