Jiang Yifan (played by Wan Qian) and Wang Yuming (played by Ren Zhong) finally found each other in the vast sea of people, and joined hands to enter the palace of marriage to form a happy family, but the sweetness of the newlyweds did not last long, and Wang Yuming lost his job because of career setbacks. He decided to start a business with his fighting spirit, but this road is full of difficulties and obstacles, and the future of this small family is still in the fog. At this juncture, Jiang Yifan found that she might have breast cancer. She did not dare to tell Wang Yuming, who was in dire straits, the bad news, so she chose to bear the pain and panic brought by the disease alone. Wang Yuming's ex-girlfriend Xiaohan was sick and hospitalized. She was alone and no one was taking care of her. The carefree Wang Yuming could not bear to see Xiaohan suffer, and decided to take on the responsibility of taking care of her, which Jiang Yifan could not accept. As time went on, the family slowly collapsed.
