I don't know why it's brought up but I guess he misunderstood the original comment. As I said there is no ntr you can read it without being bothered such comments

There is no NTR and any inclination of it.(I've read up to the latest chapter) . And the story is quite good way better than average harem novels.Its definitiely not a Dark-Romance and some characters may have tragic backstory but it doesn't necessarily mean novel should get tragedy tag. Overall as mentioned above quality and structure wise it is really up there.I think it's worth at least reading a few chapters and then decide.
