Netorare, which is more or less when someone cheats on you. Used a lot in hentai tropes for a character getting his crush/gf/wife stolen by some other guy.
i THINK i did 100% current (1.01), and no NTR on harem path. I believe the NTR path is going to be when the MC's first choice is to try to defy the neighbors and they use NTR to turn the rest of the girls away from him.
your first major choice is to either defy or to aid the neighbors, which sets the course of doing the harem or NTR path, though the only available path right now is harem.
