Does Wallflower count? Rich Landlady rents mansion to four attractive teens and offers them free rent in exchange for turning her niece into a real lady, only trouble is Sunako couldn't care less about being a lady and prefers the darkness, plus she's anemic from constantly hemorrhaging nose blood at the sight of them. Do NOT do English dub. Honestly, the manga is so much better. I don't know how it ends though, I lost track at volume 23.
