I understand your point but in this scenario Dan is saying yes not because he wants to have sex with Jaekyung, but because he needs the money for grandma so one could argue that he is being coerced into accepting this deal, and that is one of the definitions of sexual assault.
But in JK’s defense he didn’t know that Dan needed the money for grandmas bills and other debts in the beginning, in the first few chapters it gives the impression that JK believes Dan is just like any other money-hungry slut he is been with.
However, after he found out about grandma he continued with the deal KNOWING that Dan couldn’t say no.
So I still believe this is SA regardless of everyone accepting their situations.
You're just like my cyberbullies. They rub in my face every single uploads that they purchased the recent chapter while I'm sat on my fat ass waiting for my low quality watermarked illegal reuploads an hour later. Im old and poor and so what? Keep making fun of me and you'll reap what you sow or at least you'll be as old as me one day anyway. They can afford to travel to korea and china many times over and I'm 20 years older than them still have left my childhood house much less my hometown. You'll be miserable like me too one day btch and everyday i pray my cyberbullies will be too. one day i'll also be able to afford the jinx jacket and jinx merch just like them but thats when mingwa will be nearing the end of her next story of a new rapist x victim

In my opinion, it's not r@pe. Idk if y'all will hate me or anything, but if you guys don't agree just explain it and not with hatred.
So, They both agreed and the horrible sex jk did is already a deal, from the beginning.
R@pe is sexual harassment when one person want it and the partner doesn't want it but still forced to have sex with them.
Except A DEAL.
Jaekyung already reveal his jinx to Kimdan and Kimdan knows it, jk offers kimdan to be his partner and he will be paid a lot. then, due Kimdan's grandma condition, he had to accept it.
So , all force sex that jk do to Kim dan is already a deal and Kim and knows it.
And because that deal is more like becoming jk "sex slave for his jinx" doesn't meant it's r@pe, this is just horrible and force sex play (JUST SEX)
If I reread it again, there's time that Kimdan enjoy it. And because that deal, they both get benefit. Kim gets the money, and jk gets his winning title.
The real r@pe is codename Anastasia and others like that.
Thank you!
