Thank you for the spoilers each week! Love this manhwa, the characters behave more realistically than other manhwas even though there are tropes like chaebol ML, poor MC and loansharks. Everything that Yeon Oh's abusers have done to him including Jaehyuk have changed him forever. To Yeon Oh, Jaehyuk is one of many men who used him for sex, money or to get the USB.
Jaehyuk has never had to struggle like Yeon Oh, he has been able to get his way with influence and money but he can't fix what he has done to Yeon Oh with money. Jaehyuk is too focused on getting revenge on his grandfather for his mom's death, too prideful and arrogant to be a good partner for Yeon Oh even though we know they'll end up together.

YO leans in to kiss JH, who is still stunned about what YO said. YO tongues his lips and JH starts reciprocating, but when YO starts putting his hand in his pants, JH grabs and moves it away.
JH puts on a stern face and tells YO not to do something he'll regret. YO says, "what is even there to regret?" Maybe it's JH who's regretting for acquanting himself with a lowly guy. (YO probably describes himself that way after Sangho's revelation in chapter 68)
JH says that's not what he meant. YO smirks then asks what is it then? JH has his eyebrows scrunched and is at a loss for words. YO says, "See? You got nothing to say." JH still has that frustrated look and says he doesn't know how to deal with YO right now. He then kisses YO, who looks surprised.
Kiss, kiss, kiss, and next thing we know, YO is on JH's desk with his pants off. JH is loosening his ass. He's taking his time, but YO says it's okay now. Hurry up and put it in already. JH, looking grumpy, says he's not done yet, that YO isn't loose enough for him to fit in. YO sneers and asks "since when did you care about that?" JH has no response to that but says he needs YO to relax his ass as he starts putting himself in.
Some resistance, but JH forces it in. JH fucks YO on his desktop as YO bites his finger to keep his moans in. JH looses his tie then continues fucking YO. JH then leans his forehead on YO's and kisses him. He touches YO's face after, and it must be getting tender as JH leans in to kiss YO again, but something spooks him, forcing him to push JH off. JH looks in surprise. YO is frozen as he processes a thought.
Something from the night JH sexually assaulted him came back to YO. In chapter 59, YO cries as he asks JH why he's making him read into everything again. Why does JH keep on making him look like a fool? JH responds with a kiss and asks if YO was reading into that as well. Like, how many times must he remind YO that he's "just doing what [he] can"? (Long story short, it was JH telling YO he was just some piece of ass and must be why [my personal opinion] YO decided to sell himself to JH)
YO, back to himself now, covers his mouth and tells JH not to kiss him.
-End of chapter 71-
I'm glad YO doesn't ignore what JH has done to him. It's JH who seems to have forgotten. Even his own boundaries.
