Shen Nuanyan, a 26-year-old PhD in the history of astronomy from the University of Science and Technology of China, transmigrates to the Northern Dynasty during a total solar eclipse. She becomes the legitimate eldest daughter of Shen Kuo, an official at the Bureau of Astronomy.
All she wants is to return to her own time, but every attempt fails. With no other choice, she settles into life in the Northern Dynasty while continuing to look for a way back.
Who would have thought that a crisis in the Shen family would land her in the dangerous ancient post of Astronomical Observatory Attendant?
Disguised as a man under the name Shen Bozhou, she plans to lie low whenever possible and never draw attention to herself. But her abilities won't let her. Again and again, she gets swept into the whirlpool of court factionalism, becoming a shield for Zhao Jinghan's revenge.
Zhao Jinghan has always treated her as a chess piece, repeatedly warning her sternly: "Once you're in the game, your life and death are up to fate."
After being thrown into one deadly crisis after another, she decisively takes back the little affection she had for him. Who needs romance when she can build a career? Isn't it better to savor the Northern Dynasty's cuisine and see all its sights? Or just enjoy his good looks and borrow him to have a child?
Her sisters: "Yes! Very much so! Absolutely!"
Zhao Jinghan, the late emperor's third son, was slandered as a bringer of calamity after the late emperor died suddenly and his mother was forced to die as a royal consort's sacrificial offering.
Burdened by a deep-seated vendetta, he acts like a dissolute good-for-nothing who fancies men in public. In private, he is the master of the Listening Wind Tower, an intelligence network, ruthless and sinister, able to kill without a trace while chatting and laughing.
Impressed by Shen Bozhou's extraordinary talent for reading the stars, he coerces and entices her into serving him and helping him achieve his goals.
At first, he sees Shen Bozhou only as a chess piece, but he can't help drawing closer. Before long, his act of pretending to be attracted to men becomes real. Just as he decides to truly become a man who loves only Shen Bozhou, he discovers that the woman he loves, trapped in a deadly crisis, is actually female!
And so begins a long road to winning her back.
One night, he pins her against the door and kisses her passionately. "Nuannuan, please let me love you."
