The game is so inconsistent, it's frustrating, everything is jumbled up, NTR with romance, they choose the NTR "route" romance still exists and you have to choose romance options to see NTR scenes, and if you go the romance route they put NTR in you. There should be an order, They must be specific routes. If it is NTR, then the MC must not have sex with anyone because you previously chose options so that this does not happen, nor that the girls allow him to be close or that the girls feel love for the MC, since you previously chose options to destroy that romance.
The NTR route is so bad that you end up having to choose the "romance" route to see the scenes.
