It will be a harem game (all games by ICCreations end up being harems), but it's not there yet. As for NTR, it depends on what your definition of that is, honestly. Some of the girls who will be in the harem are bisexual (or maybe lesbians who make an exception for the MC). For at least two of them, they will both be in the eventual harem but continue to be sexual with each other as well. Some people consider that NTR and others do not. It does not have the tag, though, because at a minimum they are not yet in a relationship with the MC, so they aren't counted as LIs currently.
