In the context of bustling modern cities, fast-paced life and emotional hesitation are intertwined into the daily lives of young people. An unexpected business cooperation between the Gu family and the Cheng family led to a contract marriage - Gu Zhiwei, the only daughter of the Gu family, and Cheng Yanqiu, the heir to the Cheng family, pretended to be husband and wife to cope with the pressure of family marriage. The two agreed for a period of one year not to interfere in each other's private lives, but they frequently collided with jokes and sparks in their daily life together. Cafes, office buildings, and old streets and alleys in the city have become the stage where their "acting" and sincerity intersect. Hidden under the contractual relationship are their unknown tenderness and past, and legal provisions cannot capture the frequency of the heartbeat. In the hustle and bustle of the city, love quietly takes root in the gaps in the contract. The worldview combines elements of reality and light fantasy, emphasizes emotional growth and independent personality, and presents a new understanding of intimate relationships between contemporary urban men and women. The overall atmosphere is relaxed and humorous, and the details are warm and natural. Through the trivial matters of life, it shows the delicate transformation of marriage first and love later.
