Jin Yayi found that her health was getting worse and worse. After going to the hospital for examination, it was found that she was beginning to show signs of organ failure. The doctors were helpless and could only let her wait for a miracle. At the same time, Lu Zhizhu had been diagnosed with advanced gastric cancer and was admitted to the hospital. The two met in the hospital due to a coincidence of fate and became friends with each other. In an accidental examination, the doctor found that Jin Yayi and Lu Zhizhu's organs were extremely matched, which gave them a glimmer of hope. Lu Zhizhu knew that her time was short, so she decided to donate her organs to Jin Yayi after her death, and asked her to help find her brother, telling him "I'm sorry, Zhizhu can't wait for his brother anymore."
