That's what I thought when I watched it. This is by far thought, the dirtiest series I've seen that ultimately doesn't show anything, unlike Girls Bravo. The things they do to Ayano are pretty raunchy. But this series finally moved beyond and eps to eps basis. So her sister is trying to get all of her friends to turn on her. For no particular reason as far as I can tell. That's pretty nasty. Also, surprisingly believable, since I've seen it happen before.
