I know the answer is obvious, but I can't help but wonder what the end-goal of the manga is supposed to be? Rhitio-kun is so established as a character as not wanting nor into relationships, that I can't possibly see it ever happening without it being out-of-left field decision for him.
If it is a romance manga, then I think the author did a bit too much hammering of that character. Why continually say that he has no interest whatsoever in the opposite sex? His entire shtick is anti-thetical to the progression of a romcom.
If it's supposed to be as on the name, and it's supposed to be an aversion of usual romance manga, then... that screws the audience, no? Unless, it's supposed to be mainly about her becoming a better person, but that isn't super focused upon (Rihitio-kun is the POV for a lot of the chapters, and he doesn't go out of his way to discourage these behaviors in a serious tone set by the manga), nor really established as the main plot?
It really does feel like it's stuck in this romcom setting, when it's trying to be more than that. Like it wants to explore other themes, but it can't because that's not what people are reading this for.
Does anyone know the tags for whatever manga this hosted on? I wonder if it even has the romance tag in the first place.
