During the winter snow in the Republic of China, Jinzhou was closed due to heavy snowfall. Shen Qingyan, an orphan from the south of the Yangtze River, whose family was ruined and who froze on the street corner, was rescued by the gentle young man Gu Jingchen. A bowl of hot soup and a fox fur coat allowed her to seize the warmth in a desperate situation. Under the red plum blossoms in the courtyard, he taught her how to copy and identify Chinese characters and bought Jiangnan candy cakes for her; she hid her feelings and quietly took care of the courtyard, and her love secretly arose in the fragrance of plum blossoms.
The family gap was difficult to bridge. Gu's father used the rise and fall of his family to force him to arrange a marriage for Gu Jingchen, the commander's daughter, and forced Shen Qingyan to leave. Afraid of dragging down her sweetheart, she left a final letter and quietly disappeared, carrying a plum blossom hairpin to survive. Gu Jingchen lost his true love and searched for her through the wind and frost, but failed every time. What's the secret behind the separation? Can this pair of poor people break through the shackles and renew their relationship?
