The eldest grandson of Emperor Dayin and the legitimate son of Crown Prince Chengde, he was born into a noble family but had a rough life since childhood. His biological mother died young, and he grew up in the harem. Half of his face was burned by fire when he was plotted against him at a young age. He lived in an environment of darkness, suspicion and lack of love all year round. His character gradually became distorted, and he became a vicious and cruel yandere in the eyes of outsiders. In her previous life, she mistook possession for love, imprisoned Yu Qianqian with paranoia, and forced her into a desperate situation. She used all means to seize the rightful daughter. In the end, everyone betrayed her and she was poisoned by Yu Qianqian himself. She died with hatred, leaving only regrets that gnaw at her bones. The rebirth node is accurately stuck at the critical moment when Yu Qianqian is rescued from falling off a cliff and before the imprisonment and control is implemented. With all the memories and overwhelming guilt of the past life, he completely abandons forced love, carves "restraint" into his bones, and learns to love others with tenderness. The prince's decisive killing and hidden ambition are still retained in his bones. This ambition is no longer to enjoy exclusive power, but to protect Yu Qianqian's mother and son, to support a stable world for them, to redeem themselves step by step, and to be healed by his lover.
