I think it's kinda fun how messy it is rn and I feel like his boyfriend would literally not give a shit if mc cheats lmaoo
Genuinely he isn't even paying attention to him why would he care what mc does? Let him do what he wants I say!! The fact that Yuki IS in fact taking advantage of him makes this a little less fun however
Also I would never tell anyone to do this irl because that's just stupid and morally abhorrent, but if it's fiction just about anything goes, really. I'm here for the drama, not the morally correct ways of having a relationship. There's enough of that and if I want to read that I can go to Hidamari ga Kikoeru or smth
oh mama...
