Ryoko (Miho Nakayama), a 54-year-old famous Japanese novelist, suddenly suffers from Alzheimer's disease. She decided to finish her last work while she was still self-conscious. In addition to writing, Liangzi also works as a lecturer in the university. One day, when she and her students went to the wine house near the school for a drink, they ran into Chang Hai (Jin Saiyu), a South Korean student. Liangzi was curious about the nihilistic personality of the young Changhai and gradually became fascinated by him. Liangzi found that her hands were gradually unable to exert force, so she asked Changhai to be her writing assistant. Liangzi "tells" the story, and Changhai is responsible for typing. When they write the novel together, the reality and the story gradually become one, and the two fall in love beyond the age line. But Liangzi's condition deteriorated rapidly, she began to feel anxiety and fear, so Liangzi decided to let Changhai go free before her illness became more serious.
