As the eldest daughter, I've always yielded to the whims of Meldor, my little brother and the future Duke Elton. But one day, memories of my previous life started flooding my mind, and I realized this wasn't my first time sacrificing everything for a younger sibling... That was my breaking point. Enough! I've done my time! Starting today, I'll meticulously reclaim everything I was ever forced to surrender to Meldor, and I'll give that spoiled brat a good lesson while I'm at it. Just you wait!
