does anyone know any good series where the villainess and saintess or heroine get along? the protagonist can be either one and bonus points if it's GL but it's not necessary— i'm just tired of stories where they're enemies no matter how good the story is! (i'll still read them, but it'd be nicer if they're friends...!!! sobs)
