Cheng Hui is the biological daughter of Huang Fang and Cheng Jing'en, but she was secretly swapped at birth and raised by Shu Yue as her own daughter. In Shu Yue's previous life, she appeared to be a filial child but secretly resented Shu Yue for forcing her to study. On Shu Yue's deathbed, she cruelly revealed the truth: she is not Shu Yue's daughter, and she had orchestrated the poisoning of Shu Yue and her entire family, showing no remorse. She is ungrateful, cold-hearted, and malicious, representing the ultimate betrayal.
