He Yu, a 32-year-old career woman, was "fired" because she was dissatisfied with her boss's shady operation. She lost her job and broke up in one day. She was also forced to live under the same roof with Xiaoyu, a 22-year-old young man with the same name and surname who resolutely quit her job because she couldn't stand the 996 schedule. In the year without a job, the two girls with different ideas gradually changed from being irreconcilable at the beginning to relying on each other and changing each other. Under the leadership of Xiaoyu, Dayu gradually abandoned her life of getting excited and found inner peace. Under the influence of Dayu, Xiaoyu also regained her positive attitude towards life and realized her self-worth. In the end, the two completed the replacement of their identities and realized the meaning of life and work from each other. Not being "successful" enough can also be very happy. There is hope in a life that has been defeated repeatedly.
