Su Wanhe was left at a country estate from the moment she was born. In the year she came of age, the Su family finally sent someone to bring her back. She thought she was finally home, but soon discovered she had only been brought back for one purpose: to take someone else's place in an arranged marriage.
Fortunately, while she was at the estate, she had once saved a man: Prince Jing. Before she could run away from the marriage, Prince Jing unexpectedly asked the emperor to arrange a marriage, requesting her as his bride.
This foiled the stepmother Jiang's scheme, and her younger sister Su Wanyue suffered the consequences of her own actions.
But in the treacherous Su household, why does Concubine Qin always watch her in secret? Was Jiang involved in her mother's death? And what role did her father play in it all?
