She is born into a boring novel till one day she gets engaged to the duke. She thinks the other female mc is the duke's real lover so she is just trying to annul the engagement and not die.
Chap. 12
Reincarnated before the story happens, so she can smash the villain's father so the homeboy is never born. I like the male lead. Classic tsundere but not an ass.
Chap. 24
