On the day of graduation, Wang Chunzhen was taking pictures at the school gate in her bachelor's uniform. She turned around and bumped into someone - her first love Gu Huaian, whom she hadn't seen for five years. He was wearing a white coat and returned to school as an outstanding alumnus. Among the photos scattered around, there are photos of them together. The moment the air froze, Wang Chunzhen thought this was just an unexpected reunion, but he didn't know that the rest of his life would be completely disrupted by this encounter. Her roommate suddenly left, and she couldn't afford the rent on her own; she encountered sexual harassment at her first job; and the man she had broken up with so cruelly appeared again and again in her most embarrassing moments. They were forced to become roommates, and in the kitchen late at night, in the convenience store early in the morning, and in the corridors of the hospital, they slowly pieced together the five years of their absence from each other. Until she discovered that the reason for the breakup was not what she thought at all. This time, she chose not to escape, but to muster the courage to face the truth hidden deep in her memory. This is a story about reunion after being broken, and it is also a story about how ordinary girls find their courage and themselves in the quagmire of life.
