Wu Gong and Jiang Li are a pair of post-80s graduate students studying in Shanghai. After graduation, they decided to get married and stay in Shanghai despite their parents' opposition, but they were overwhelmed by the endless difficulties in life. After hardships, Wu Gong and Jiang Li finally entered the palace of marriage, but they didn't expect that bigger troubles were waiting for them. Wu Gong used the down payment of the wedding house that he had finally gathered to see his father, which caused great dissatisfaction from Jiang Li's mother. One wave has not yet settled, and another wave has risen. Yue Xiaoqing, Wu Gong's ex-wife who had a short marriage, suddenly appeared, with a 5-year-old son that Wu Gong didn't even know existed. This once again challenged Wu Gong and Jiang Li's already fragile marriage. The contradictions in the small family have risen to the contradictions of the entire family, and Jiang Li's mother insisted on divorcing her. After all the twists and turns, Wu Gong and Jiang Li finally realized and felt the true meaning of life. They decided to stay together in the years to come, and a better tomorrow is still waiting for them.
