Helena: Master Of The Guardian Stone

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. "Don't you want to take revenge on those who thoroughly deceived and killed you?" I decided to accept the devilishly sweet offer. This time, I will definitely get the guardian stone and become the head of the household. I will give you back as much or more than what I suffered. Until then, I will believe no one. But... "From now on, no matter what happens, you must never stop and run." The image of him trying to save me, his eyes running in despair, couldn't be erased from my mind. The fiancé I loved was looking at me as I died, but why were you running to me with those eyes. You, who I thought was my sister's person... I want to know where your sincerity lies.
