He's adding it. It's not in yet. He's done nothing but tease NTR the whole game while saying there won't ever be NTR. Bad Endings won the pole so he got the ok to put the NTR he's always wanted to into the game. Since he said his next game was going to be NTR focused, now he gets to add it to GE.
This is why I don't trust devs anymore. This isn't the first time you get X amount of updates into the game for the dev to change their direction. People are upset and rightfully so. It seems the dev is all for NTR though so he got exactly what he wanted in the end.
