Honestly, this series would probably be better as an H series....
If it was an H series, I wouldn't have found it, and I think it might have been less good at any rate.
What I've found fascinating about the narrative is how balls-to-the-walls emotional it tends to be. What first comes to mind as an example: I read Fujieda flashing Shou (and everything leading up to it) not merely as sexual harassment, but as a desperation act from a particularly anguished teenager with low self-esteem. In most other manga, she'd just shout out her feelings while crying, and maybe she'd cling to him, and that would actually be more than okay, depending on the execution.
But there's something genuinely special about the extent of her effort being the baring of her body, that-- if one is interested in doing more than making a moral judgment about a fictional character, not that such isn't necessary
at all-- beckons the sequence to be understood more "holistically". It also wouldn't have the same impact in an H series, because 1) characters in H stories are generally a quarter of a person and otherwise loose collections of attributes, and 2) the lack of sexual restraint in those would cheapen such a moment (there'd be more views of naked bodies before and after this sequence, if not outright sex).
Also, Fujieda waiting for an opportune moment to tell Shou he was handling a sculpture of her was actually smooth.
I've mentioned this before, but I think another entertainment factor in this narrative is how emphatic it is about the "male" and the "female". The male lead is sturdily built, the female lead practically the body of a fertility idol, and there's a
lot of palpable tension stemming from the contemplations and reckonings with their feelings about the other on both the emotional and sexual levels. That tension that would have been released two or three times over by now in an H series, because... well... H series are meant for wanking, not contemplation.
