In my previous life, I was Lu Tingshen's substitute Bai Yueguang, and I died protecting him from a knife.
When I was reincarnated back to the day I was picked up by him and brought home, I turned around and walked towards his nemesis: "I'll help you bring down the Lu family, you help me."
Later, Lu Tingshen knelt down and begged me to turn back, while that nemesis pressed me against the wall: "You can only be mine."
