the reincarnated villainess was enslaved by one of the love interest and in the end (the end of the prologue I mean), died. the heroine would try to save her by going back to the past. that's enough information right? I remember the story, but I don't remember the title, it's not on my reading list (I think), and I haven't saved it in an epub yet. geez, why didn't I make an epub of it at that time. even though I have an epup of most novels I read.
