This work tells part of the story before Zhang Ji established the "Lovelorn Sanatorium" in the previous title. Zhang Ji was originally an ordinary migrant worker, but he suffered a sudden accident, and his only relative died in a factory accident. Afterwards, he was forced to lose his job, blamed for an accident by an unscrupulous boss, and suffered a series of unfair treatment and blows such as telecom fraud, and was arrested and imprisoned. When his life fell into a trough, he met his father's only relic during his lifetime, a talking rabbit, and started the funny work of "Lovelorn Sanatorium".
