Peerless Tang Sect: When Did I Have a Sister?

If there hadn't been this extra "sister", would the ending have been different? A strange girl comes to Douluo Continent, and unknown variables quietly rewrite the chess game of the God King. She came here alone, not even remotely related to him. "From now on, you are my sister." Huo Yuhao swore an oath to protect this only relative to the death. He only wanted to protect her for the rest of his life. But the longer the road we walk side by side, the harder it is to secure that protection. "Brother, why can't I be the only one in your eyes?" Until that day, the girl who had always been gentle and quiet raised her eyes and said word by word - "I don't want to be your sister." It was also from that time that Huo Yuhao realized that something was wrong with his sister.
