I’m the Master of this Life

Story:

The guardian stone of the family appeared to me. To me, the illegitimate child, not my half-sister who is my enemy. Since then, my treatment changed. It really felt like I was part of the family. However, as I died, I realized that it was all an illusion at the hands of my fiancé. That everything he did for me was a scheme by my half-sister to take the guardian stone.
