I don't know about you, but the music at the start of the game makes me feel melancholy, it gives the game a sad touch, as if we should expect it to end in tragedy.
I'm taking my time to finish this game, but frankly, it's one of the best Eroge works I've played.
It's a pity we can't interfere with the MC's body so that Rouge can become a woman again at some point, because I'd like to see how the girls would react if they found out.
At the moment, only Rita's mother and the granny (a former member of the organization) know about it (along with Lovely, perhaps).
