Hmm, but he could come to the realisation that he was a victim of an abusive ex, and he has been "thrown away" (as the other character keeps repeating) without being further abused and the whole "overwrite xyz by doing further xyz". If the dark haired character was honest from the start that he was "thrown away" himself, and shared his own experience, his own realisation, it would be a less cliche "abuse is acceptable with the right person" plot. Even then, the fair haired character doesn't need to be prompted or force to come to said realisation, nor should the other character feel he has to share his personal life like that, but hey there probably wouldn't be much of a plot if it were rational presumably, seeing as it seems like it's going to be quite a rather short series, rather than one long enough to really explore such an abusive relationship and the legacy with depth.
Um nowhere did I say it wasn't abusive. I simply pointed out how it was an unusual take. Usually stories like this go from pleasure to pain but this takes the opposite direction. And that's all I noted. So I don't know why *you* felt the need to point out what you did?
Also, did you not perhaps consider that the reason he doesn't talk to the uke is because he had the exact same experience of someone trying to help him but he didn't believe what the other person was trying to tell him? That would be the first thing I'd consider, after all, given that most abuse victims are manipulated psychologically by their abusers to be dependent on them, which is something you'd have to be giving the ex a pass for when you focus solely on the abusive behavior of the seme only because he didn't talk to the uke.
Go back and reread, sweetcheeks. Nowhere did I justify abuse. I SAID the seme was abusive. Oops? But I DO think your response was justifying abuse. Because basically you just ignored how abusive the ex was by saying that talking ALONE would solve everything which MEANS you would have to victim blame the uke for not being able to extract himself from the situation caused by the abusive ex.
Huh? The point is the dark haired characters behaviour is criminal and logically not productive, as he is "triggering" the other character and forcing him, rather than giving him agency and support, even if he feels he is helping. The fair haired character does not need to accept his help, and mentally not be in a place to consider his ex as abusive. The fair haired character has been confined, sexually assaulted by this uncommunicative stranger among other crimes, and is clearly fearful. If the plot were to be in anyway rational, it wouldn't try and frame that such abuse is okay, if doled out by "the good guy".
Seeing the person your ex cheated on you with, knowing he was abusive, the first thing that comes to mind would either to not get involved, or try to have some sort of conversation, but the plot is anything but this.

Yeah, I like this one. This is an unusual take. Usually we have the author convincing people that they like pain even if they say no but here we have the opposite. This would be such a cool psychological story if that happens.
