Even without sharing or exhibition points and only committing to D's path, you still end up an exhibitionist and both F and D make comments about other potential sexual interests, what I requested is that for those who don't end up making sharing and exhibitionist choices shouldn't have a story that leads them there anyway.
You said "It's kinky, It's not romantic" and that is not really a logical conclusion, and it is definitely romantic, and without a doubt a visual novel. It's not really a game. There is no game mechanics to it, Love points, Friendship points, Sharing points, determine how the story progresses, at least in the traditional sense, it's not a game. At the end of the day, I really wish them luck however they choose to proceed with the story, it was an entertaining novel, not perfect by any means, but entertaining nonetheless.
