Agree for the rape tag, absolutly hated this chapter. No need to have the NTR tag in my opinion.
For some extra context on my thoughts, I was thinking NTR because after she's raped it's heavily implied that her crush is raped in front of her as well. Which feels very NTR to me at least.
I mean, I can see where you come from, but considering that her goal here is not to force them apart, but to force them together, I'm not sure it technically counts as NTR.
