My Next Life as a Villainess All Routes Lead to Doom! (Manga) Volume 4

At the age of eight, Katarina, a girl of noble birth in another world, has an accident that unlocks her memories - of playing an otome game that's exactly like the life she's living now.

There's one problem: she realises that she's playing the role of the villainess, and only bad endings await her! What will it take for her to "break the game" and live a happy life?
