Corrupted girlfriend and submissive boyfriend? Sounds like this VN is targeted for a quite specific audience, rather than to cater to a variety of them. Submissive character is one I'm not willing to play, it's not in my nature, I prefer to be in control and at most share it, but I will not submit to no one, don't care who it is
And I wouldn't want a girlfriend that can be corrupted to a point where she will be sucking every dick in town, with a girlfriend like that you're better off with a prostitute.
