This drama is a pure love story that depicts the miracle of love over 10 years. Kitazawa Nao (Toda Erika), a 34 year old doctor with juvenile alzheimer's, falls in love with Mamiya Shinji (Muro Tsuyoshi), a 41 year old novelist who works part time with a moving company one month before her marriage to Ihara Yuichi (Matsuoka Masahiro). Shinji keeps her bright and healthy, but Kitazawa's illness has her fearing she will one day forget.
