Ning Yufan, a medical student who stayed up late to study for his thesis, unexpectedly fell into an ancient couch embroidered with entangled lotus patterns when he opened his eyes, and became the "young lady" who needed to pray for the old lady. As the incense of Ci'en Temple was lingering, she instinctively smelled the hidden blood. She rescued the seriously injured man in Xuanpao deep in the bamboo forest. She used a silver needle to stop the bleeding and wrapped the wound with silk, but accidentally left behind a handkerchief embroidered with the word "traditional". When she turned back, there were dried blood stains on the farmhouse, and no trace of the man or the handkerchief. But she didn't know that the man who was rescued turned out to be the prince who was plotted against by the prince. He was holding the square handkerchief and ordered people to track down the woman with the word "traditional" - an unexpected encounter has quietly tied the fate of the two of them.
