The royal family feared my clan's mechanical mastery, so they kept me, Claire Foster, in the palace. In my past life, I fell in love with the Crown Prince and helped him take the throne. Once he ascended, he buried my entire clan alive on charges of treason. Now, reborn on the day of our engagement, I marry his rival, Ethan Carter—while the Crown Prince is left weeping with regret.
