Wu Jiawei (played by Ma Junwei) has been complaining about himself for many years. Finally, one day, he made a major decision to do something he has been looking forward to for a long time. Jiawei's mother, Ah Mei (played by Gu Meihua), was diagnosed with snuff cancer when she was 26 years old. Jiawei was only 6 years old at the time. Jiawei and his father accompanied Ah Mei in fighting cancer. Although he was young, he was very sensible. Unfortunately, Ah Mei eventually succumbed to the disease and passed away. Jiawei became more silent because of his mother's departure, and took all the responsibilities on himself. This guilt made him depressed and fearful for many years. Jiawei's attending doctor Mei Si (played by Yu Xiangning) was abandoned by her father and became an orphan. In her eyes, Jiawei's longing for his mother is just a trivial matter. Her indifference forms a strong contrast with Jiawei's love for his family. But with Jiawei's help, Mei Si was finally able to make up for the lack of family affection for many years.
