I haven't played the game yet so I don't know exactly how things work in it, but romance and mind control don't have to be mutually exclusive. Why not throw in some consensual mind control, or even consensual full brainwashing? People do bondage play and even sign slave contracts in real life, so I don't see why mind control would be any different. Especially if someone has some kind of hangups that they can't get over but could be completely bypassed through mind control. "The truth is, I've never been able to feel like I'm truly loved. No matter how much my partners try to do for me, there's always this anxiety in the back of my head telling me it's not real. Can you make me feel it? Drill it into my head as an absolute fact that no matter what happens, you'll always love me? It doesn't even have to be true - just make it feel real to me."
