The sentiment for NTR in LiL tends to be girls relationships with other girls. There are a few of those kinds of scenes, mostly with characters that the MC hasn't gotten with yet, but the detractors hate it for existing.
You'll find this sentiment in basically any game that has any amount of lesbian content and is also tagged Harem.
I'm pretty sure we'll see the sentiment pop up in this game too, sooner or later. There are some yuri undertones for some of the girls.
