I have always been told by my half-sister, who is beautiful, that I can never be happy forever because of the birthmark on my face. Even after being chosen as the fiancée of the crown prince. And after my fiancé was stolen by my sister, what did I decide to do?

I was born with an ugly red birthmark on my face. My mother died shortly after I was born, and my father quickly remarried. When my half-sister was born, I was locked away in a separate building and ignored by my father. My half-sister always made fun of my birthmark, calling it pitiful. But I never talked back and just stayed silent. When I became the Crown Prince's fiancée and went to the palace, he immediately asked me if the birthmark couldn't be hidden. When I answered that even makeup wouldn't work, I was sent to a separate residence and ignored. Then, a few months later, I was told that he was breaking the engagement with me and that I should leave, and that my next fiancée would be my half-sister... My father also said he didn't need me, so I went to stay with my mother's relatives... Do you know what karma is? I have made a decision about something.
