Kitazawa Nao (Toda Erika) is a doctor. After dating her boyfriend Ihara Yuichi (Matsuoka Masahiro), who is also a doctor, for several months, she finally got engaged and prepared to join hands in marriage. During the move, Kitazawa Nao met a moving company worker named Mamiya Shinji (Muro Tsuyoshi). Shinji was once a well-known novelist, but gave up his novel career halfway. Coincidentally, Kitazawa Nao was once a fan of Shinji. This fateful encounter made Kitazawa Nao gradually realize that what she had was not what she wanted. She resolutely canceled her engagement with her boyfriend and turned to passionately pursue Shinji, who was far from her status. At the same time, Kitazawa Nao was diagnosed with Alzheimer's disease, which also meant that there was less and less time left for her and Shinji.
