Dammit Yohane, why must you walk the path of the NTR?
Yeah, no kidding - it's not funny or exciting; it's just emotionally arousing by making you pissed off. I just end up not wanting to not look at their stuff anymore - I want entertainment to be entertained; not to have a plot/scene of NTR with no resolution.
What I don't get about NTR is usually the one being stolen doesn't really seem to be enjoying it. Like here; Hatate doesn't look to thrilled about this. Can it really be called cheating if the stolen person isn't a willing participant? Can it really be called stealing if said person isn't getting some emotional connection with the villain over their (former?) partner? I get that being forced to watch this would suck, but would your lover being pressured into sex or raped really destroy a relationship? I don't think so...unless there's mind break involved, but that's a whole different can of worms.
