Lan Luo kept guarding the palace for his daughter, but because Qin Yance preferred Bai Yueguang, he lost his beloved daughter. Desperate, she used the power of the secret door to leave the capital, and met Wen Jue, the young master of the secret door, in the south of the Yangtze River. He protected her for ten years, helped her get out of the gloom, opened a restaurant and taught apprentices to live out her life. Faced with Qin Yance's sudden awakening and crazy entanglement, Lan Luo joined hands with Wen Jue to face the past, and finally received the emperor's decree to cut off the past, stay with Wen Jue, and usher in a new life in the south of the Yangtze River, using gentleness and tenacity to write a new chapter of his own.
