やり直し令嬢のリベンジ

My fiancé and my brother have hated me for ten years. They're convinced that I'm constantly bullying the woman they adore. At an awards show, I'm condemned by everyone and stabbed to death. When I open my eyes again, I realize I've gone back in time to two years earlier. Once again, she pretends to be a victim and demands an apology. This time, I snap and decide to show her what real bullying looks like.
