I think it was towards the end where the second guy (who turns out was just ordered by that bitch to rape the lead guy so the red haired beautiful boy will think that the lead guy is cheating) almost raped him and red haired guy left but he came back to get his boy back! Does this make sense? (づ ̄ ³ ̄)づ

Any yaoi where uke is raped in front of seme or almost raped in front of seme, thanks
