During the Shangyuan night banquet, after getting drunk, the indulgent ninth princess Jiang Jinyue bumped into Xie Ji, the new top scholar. Under the light of the lamp and the moon, the man was graceful and graceful. The moment he held her, she was sure that this was a God-sent match. With a marriage proposal, she married into the Xie Mansion with great expectations, but on her wedding night she learned that her top pick had already had a sweetheart - a "green plum" who died young.
What makes her even more confused is that there is also a "sister" in the house who is as cold as the moon, his wife Yan Wujiu. Xie Ji treated her with as much respect as ice, but he treated Yan Wujiu with the utmost respect. Jiang Jinyue was unwilling and angry, but under the silent care and amazing talent of the "sister", she gradually changed her mind. She discovered that Yan Wujiu was afraid of cold and heat, had calluses on his fingertips, and was not at all like a boudoir woman in his intellectual and demeanor.
Once in danger, Yan Wujiu showed off his skills, and his calm and decisive look instantly struck Jiang Jinyue's heart. She suddenly realized that the person she really admired was this "pillow person" whose gender was a mystery. However, when feelings secretly arose, Xie Ji's political enemies spied on him, and the hidden crises in the mansion followed one after another. When Yan Wu Jiu was forced to take off her hairdress in the main hall to protect her, revealing her shocking male body, everything turned upside down.
The crime of deceiving the emperor caused an uproar in public opinion. What Jiang Jinyue faces is not a love rival, but the entire worldly ethics. What kind of past and promises are hidden under the secret that Xie Ji silently guards? This situation, which started with a ridiculous mismarriage, trapped three people. Who is sinking in sobriety? Who is pretending to be affectionate? And how to place the heart that abandons identity and gender and beats purely for him?
