Every time they have sex because of the power imbalance
Dan is literally in debt to the Horse and repeated thinks about how he doesn’t want to have sex but has to. Jk does something Dan doesn’t like every time they “have sex” which is not foully informed enthusiastic consent therefore every time they’ve had sex was rape. Including the time before Jk’s American match bc Dan was under the influence of drugs. But that was unintentional ig since Jk didn’t know. Along that same vein, Dan raped Jk when he was drunk the night before his birthday bc Dan was sober and Jk was fully out of it.
I digress
But the answer your original question
I can’t give you a chapter bc it’s every time they bone bc Dan isn’t actually giving consent

Can we really talk about rape when Dan is fully aware of what he's doing (he has to)?
You say it yourself : The chapter where Dan was under the influence of drugs, jjk didn't know so doesn't count. But on the other side, when jjk was drunk and out of it, Dan took advantage of the situation even tho jjk gave him the choice (bro jjk drunk, can we talk about that? He's was like back to his 6yo).
Can anyone tell me what chap did jaekyung raped dan because I never really noticed it after rereading it 2 times, and then news flashing everyone misinformed saying jaekyung raped dan when in fact hes just a normal red flag man with bad attitude and temper?
