Xie Keyun, the second daughter of the Xie family, was born of a concubine. She was the result of an affair between her father, Xie An, and her mother, and was therefore bullied and ostracized by her elder sister, Xie Keyin, and elder brother, Xie Du. The family matriarch even made mother and daughter live in a filthy pigsty. For Xie Keyun's sake, her mother endured it all. As a child, Xie Keyun swore that one day the three of them would kneel and kowtow to her and her mother in apology.
Eighteen years passed in the blink of an eye. Xie Keyun had grown into a graceful young woman who could easily have ranked among the top ten beauties in the capital, had she ever been seen there. Unfortunately, she had been kept under lock and key and rarely allowed outside since childhood. The people of the capital did not even know the Xie family had another daughter. Before long, her mother fell ill and died. Her dying words were a plea for Xie Keyun to escape. Heartbroken, Xie Keyun fled and vowed to make the Xie family pay. From then on, she wore a mask to keep them from recognizing her and set about making a living. Having suffered so much herself, she felt deeply for those in the world without a home. She opened a teahouse called Jia'an House, welcoming guests from far and wide so they could feel the warmth of home. While running her modest teahouse, Xie Keyun quietly laid the groundwork for her revenge.
But everything changed when she met a eunuch named An Xian. The two used and cooperated with each other, eventually becoming close friends. By chance, Xie Keyun discovered that An Xian was not a eunuch, and slowly fell for him. But An Xian was burdened by a terrible grudge and could only bring himself to reject her. In the end, they cleared up their misunderstandings and avenged each other, then lived happily together, settling forever at Jia'an House.
