My Visual Novel Idea

Kind, sweet, charming, and attractive, Minami Kousaka is the girl anyone would be jealous of. She's the one that Trill's fortunate enough to have her for. However, he still wonders if he's fit enough to call her his girlfriend. Not to mention his time as a waiter in a Butler Cafe. She doesn't complain about it, but that's another story and worry for him. One day, a thought came to him and said, "Why can't I have someone else have her anyway he wanted her to be in order to keep her from being alone and lonely?" You think that sounds ridiculous? Sure, but as he imagines her with some other boy, he starts to get incredibly aroused.
