Okay, I know this is gonna start an argument BUT I want to say it,
I don't really like jaekyung but the fact that he is getting so much hate like this is so confusing to me, have you seen other seme and what they do? But this is not the main point here, the point is that he paid Dan to do that stuff, there was a deal, means consent, even if Dan hated it, there was a deal, jaekyung paid off Dan's debt and is paying him not just for the physical therapy but for the sex too, so idk what the big deal is? Yes, he is a jerk but that's who Dan decided to work for and he fully consented to the terms and conditions for the deal. (Even if jaekyung took advantage of his situation to reach his goal.)
