However zhongli loved and longed for Guizhong, who is one of his concubines... One day he had enough and hired a assassin to eliminate you. On your last breath you saw zhongli and guizhong hug and laugh.
Zhongli:"They're finally out of the picture. If it weren't for them we would've married already, guizhong. They were the worst that could happened to us."
Guizhong: "You're right my love, I bet they planned all of this just to marry you!
