Its netori.NTR(netorare) means some stranger or a guy you know fucks Daisy the same way.
With the way this game is designed, written, and as been rewritten over the years it is almost impossible for there to actually be any Netorare to the MC.
The vast majority of the girls within the game aren't seeing Mik... I mean Tommy exclusively, meaning that if Daisy for example went to go fuck Morgan it wouldn't be NTR as per the points mentioned.
Hell even his supposed girlfriend Alex who originally agreed to an open relationship with him from the being is no longer his girlfriend but "Just friends who sleep together" (Tinymon tournament) So with all these open relationships, nothing being exclusive, and all parties involved so far agreeing they can fuck whoever they want good luck with actually getting any of that kind of NTR within the game that way.
Heck what makes it even harder is that this guy has such a huge shlong and has extremely well oiled sex skills that I doubt it would even be realistic with any of the girls/milfs he has slept with going forward.
