Nanmu only sleeps with his friend voluntarily twice in the entire series so he’s not going back and forth at all. One time it happens because he’s finally figured out that pleasure is possible after years of being assaulted. The second time it’s because of extraordinary, shattering despair. Indeed, if the story bothers you, it’s best to stop reading. I’ve done that with many comics.
That is literally what I said I was gonna do lol I said I was gonna drop this also it's more than twice he sleeps with them voluntarily from ch 1 when we see him sleeping with blond guy at work it was voluntary the only unconcensual part was the nasty ass gang rape nanmu even says he continues sleeping with them after the punishment ended it was like twice with blonde guy I believ and three times with black haired that we've seen so more than twice hense I say he keeps sleeping with them but yes anyway I had already said I was dropping this so you don't need to tell me what to do also like you said he finds out the pleasure is possible after many years but he found that out with the seme so I don't see why he had to feel that pleasure with someone else I didn't feel there was a need to but anyway that just my opinion your free to feel differently unless it's just giving wrong information

This manga is pissing me off sm this is exactly why I don't read manga where they sleep around with loads of people gave it a chance cause I like this author but he's still fucking around im sick of it
I seemed the warmth you showed me from someone else why why was it necessary to continue fucking other guys when you know both your feeling ffs in genuinely pissed off hate hate hate ppl who sleep around at first I gave benefit of the doubt because of his reasons for doing it but now it's just a ducking joke sleeping with anyone who's there fucl off
