After reading all these comments I remembered a manga similar to this one. It's about a guy that has a birthmarc in his butt cheek that makes all women that sees it, no matter if it's from a photo or live, fall madly in love and get extremely horny as well towards the guy. My point is that guy had a girl he liked, but after knowing about what the -lets call it tattoo for simplicity- tattoo does to the girls he starts doubting the girl's feelings towards him, and a whole lot of stuff happens not to his liking because of the tattoo (H stuff). I believe if rokudo were to take that guy's actions he would feel really guilty about that knowing how he is. Btw, after having sex once the girls went back to normal without any memory of what they did only knowing about it if he told them himself.....what if rokudo did something to the girls (obviously not sex of course since its not that kind of manga), like kissing them and that lifted the spell on the girl? Would she lose her memory about rokudo? Would she just stop being In love with him? Would she distance herself from him or keep being near him but this time actually falling in love with him?
