@Vasqueztion Well, I usually follow the principle "everyone is looking for fun and having fun as they want." But since I am a psychologist in real life, I have a professional deformation and I very easily turn into a moralfag at the slightest trigger. As you can imagine, such hypocrisy is even more "good" reason than necessary. This manga is a case where I better not think about it again, lol. I dumped a few bags of salt over how this manga idealizes toxic behavior (as I said before, if rival were male or MC was originally lesbian, it would have a much, much more negative reaction), but that was my maximum.
Well, for me personally, it doesn't look like romance either. Of course, some scenes or lines at least hint that the MC is looking forward to lewd content from Nanako, but at the moment it looks more like an expectation of "pervert fetishes" than a genuine sexual interest in her. The only thing that bothers me is how the innocent Nanako becomes a "victim" of some not entirely innocent abuse by lead, but as long as that doesn't go beyond sitcom boundaries, I have no complaints. But then again, who knows how this will develop in the future?
