In her previous life, Ye Zhengzheng sacrificed herself to preserve her sister's dignity, only to meet a tragic end, dying with deep resentment. Reborn at the very beginning of the tragedy, she refuses to sacrifice herself for her sister again. Instead, she uses her exceptional musical talent to secure a place for herself.

Step by step, Ye Zhengzheng carefully plots her moves, using the Crown Prince's influence to gather evidence and clear her family's name. She takes control of her own fate, makes her wicked sister suffer the consequences of her actions, and carves out a bright future for herself from the depths of adversity.
