Whatever you say Mister Captain Cuck Save a Hoe. I'm not even going to argue. With you. To be honest I'm here telling the truth and steering people away from lying devs and players like yourself. This was said to be vanilla harem game. 2 love interests were removed to make room for a whore main LI. There isn't anything compelling about adding a whore with a sob story that has been used in other games before that were abandoned. If the dev was up front about NTR in the first place we wouldn't be having this conversation in the first place.
1. Is Chika a whore?
2. Is she a main love interest?
3. Is she fucking anyone else that's not the MC?
Go ahead and answer me those questions. If they're all yes (which is the correct answer btw) Then it's NTR. Please stop trying to tell people otherwise.
