My Fiancé Forgot About Me, so I Entered a Fake Engagement with the Neighboring Prince (But Apparently, I'm His True Love?!)

In her past life, Liefé, eldest daughter of a ducal house, was the feared dark sorceress Laurie—a villainess so powerful and feared that she lived in isolation. Reborn, she vowed to rewrite her fate: no more loneliness, no more fear. Surrounded by loving family and a devoted fiancé, her new life was finally on track… until her sweet-faced younger sister Aria stole her fiancé and drove her out of the house. Back to square one? Not quite. To reclaim her pride, Liefé crashes Aria’s engagement party—with the Crown Prince of a neighboring kingdom on her arm. It was supposed to be a one-time deal… so why is the prince now asking for her hand in marriage? A tale of revenge, rebirth, and unexpected romance begins—where a former villainess might just become a queen.
