im sorry but you are literally doing a false comparison, so if the story isnt focused on the guy like a lot of them arent it isnt ntr? from what youve said it seems like that, but ive read plently of ntr that have the guy not knowing at all, so they arent ntr? the term is literally translated be...
so you are one of those that believe that its ntr if the girl doesnt have interest in the guy? if there is no relationship there is no ntr, the guy got his hopes up and it simply didnt amount to anything, nothing was taken because there was nothing in the first place
i mean the childhood friend didnt do much, she had a boyfriend(or at least claimed to have one) that isnt really something bad, it just makes the mc sad.
he is trying to find a reason to keep them away, he doesnt want to talk to them, they are the ones that want to talk, but he isnt interested, also they didnt do anything to solve the misunderstanding at all too
Ngl I was really surprised when I saw that this one got a manga, mostly because the first time I saw her was at the author twiter when I was searching for monster girls, glad he could make his favourite oc(or at least it seems so) into a manga.
