After her mother was brutally killed, Zhen Yi barely escaped, only to encounter the marquis's second daughter, who looked just like her and had only a breath left in her.
At the dying girl's request, Zhen Yi assumed her identity and headed to the capital. She had to avenge her, find the murderer who killed her own mother, and search for her missing father.
On the way to the capital, she rescued the young prince Cui Yichen. Hoping to get something out of him, she ended up dressing him as a woman out of expediency. From then on, he was constantly at odds with her, difficult and vindictive.
With him to deal with and hidden enemies lurking in the shadows, Zhen Yi thought, "I might as well keep him for myself, so he can't go around causing trouble for anyone else."
They schemed against and bickered with each other, going from a life of chaos and mutual loathing to burning passion and a love they couldn't live without.
