Game of Love in Eastern Dream

Zi Qi is distrustful of everyone and cares only about his sister, Mu Yao; he detests Liu Fu Yi, who is in love with her. He is rebellious and ill-tempered, listening only to his sister Mu Yao, and consequently, he is usually alone. He is initially wary of Lin Yu, but his affection for her grows over time.

Zi Chi was born of a forbidden love; his father was the God of Demons, and his mother was a Goddess of Purity. However, after his father was killed and chaos engulfed the Mountain of Tranquility, his mother, Halin, took the seven-year-old Zi Chi to a mortal city. Zi Chi possessed the combined powers of both the Goddess and the God of Demons—a force capable of destroying the world—and his blood could vastly amplify demonic power. To contain this, Halin bound a magical ribbon into his hair to seal his powers and erased his memories regarding his identity and family; she was then forced to leave him behind and sacrifice herself to put an end to the chaos.
Zi Qi, who was amnesiac and adrift, was taken in by the Mu family and renamed Mu Sheng; Mu Yao, the family's daughter—two years his senior—treated him with the kindness of an older sister, and he grew deeply attached to her. After Mu Yao's family was killed, the two spent years traveling together. Twenty years later, they encountered Liu Fu Yi and went to the Yan City magistrate's estate to solve a case.
