Tbh, got to read this because of the NSFW work and sad they did nothing with it really. No romance or anything much really in it. Think the best example of a story that is NSFW and got a normal manga version is maizumi Brings All the Gals to His House. Like that one does it right.
Imaizumi is the goat, I wish half the romcoms had the chemistry that guy has with the girls.
Anyway, I re-read chapter 13 to 23 and found myself disappointed, it seems the only time we see Hinata take the initiative and do something nice that isn't just a gesture you would or could do with a friend (like cooking) is in chapter 17 when he gives her that hairpin BUT EVEN is just a flashback.
Bell has to initiate everything, it feels like Hinata barely has a strong reaction in kind to her and is very meek or friendly rather than loving.
If you wanted to see the couple have lewd moments like in the hentai then you lose and you just get a lot of random panty and boob shot, but to me these are without rhyme or reason and thus I don't find them appealing.
The way they introduce new characters feels like the author was bored and already out of ideas. The more I think about it, the more I am disappointed.
