Su Wanqing, an ordinary white-collar worker struggling to survive in the modern city, accidentally signed an incredible contract with Ye Junli, a mysterious CEO who claimed to be from the "upper world" in order to raise life-saving money for his mother. She originally thought that this was just a game played by a wealthy family, but she never thought that this powerful man's true identity was actually the Lord of the Immortal Realm who controlled the world.
A contract drew her into a huge whirlpool that spanned the human world and the fairy world. Why did the cold and ascetic Immortal Lord choose a mortal like her? What kind of secrets does she hide that even she doesn't know about? When the dusty memories were awakened and the conspiracy of the three realms surfaced, she discovered that this seemingly accidental encounter was actually a fateful entanglement that spanned thousands of years. From the mundane city to the Nine Heavens Immortal Palace, from a novice in the workplace to someone who can stand side by side with him, Su Wanqing was forced to embark on a road full of thorns and adventures. But that seemingly ruthless man supported her in crisis after crisis.
