Leaving My Ungrateful Family, I Start Anew

Synopsis

I was the Sterling heiress, but all anyone ever cared about was my cousin. They kept stressing that since I came from a prestigious family, I was supposed to know how to swallow my pride and give in. In my previous life, I cried, begged, and fought back, but none of it mattered. In the end, I only lost my life for nothing. I was given the priceless chance to time-travel. Alright then, I would let her have my parents and brother's affection. She could have all the empty titles and reputation. I would even let her have my fiancé I have been betrothed to since childhood. I had given her everything she ever wanted, so why was it never enough for any of you?
