This work is adapted from the Tomato novel "My Wife Didn't Turn On the Air Conditioner, So I Filed for Divorce on the Spot" by Cui Youdao. Li Cheng filed for divorce because his wife Bai Wan did not turn on the air conditioner for his son, but allowed his first love Gu Minglang and his daughter to turn on the air conditioner at home. Bai Wan continued to favor Gu Minglang and his daughter. When her son had a fever, she still took care of the other's children first, acted as a mother for her daughter, and did in vitro fertilization examinations with Gu Minglang. Bai Wan used the excuse of saving the other party's seriously ill daughter, but in fact she was deceived by Gu Minglang with fake medical records. Li Cheng insisted on divorce and lived a stable life alone with his son; Bai Wan lost everything after being deceived by Gu Minglang and eventually committed suicide.
