Wang Ru and her husband Xu Ping'an were diagnosed with cancer at the same time. With expensive medical treatments and considering their son Xu Yang, who had just entered high school, Wang Ru was the first to choose to give up treatment and persuaded Xu Ping'an, who was already in the late stages of cancer, to also give up treatment, leaving the money for their son Xu Yang, but because of this, she was misunderstood by Xu Yang. After Xu Ping'an's death, Xu Yang became sensitive and rebellious. At his coming-of-age ceremony, in front of all the teachers, students, and parents of the school, he accused Wang Ru of her crimes and declared that he hoped Wang Ru would die soon, unaware that at this time, Wang Ru did not have much time left.
