The originally happy family of three fell apart due to a car accident. The bus that the wife and daughter were on fell into a valley because the driver was sleep-deprived. In the end, the wife died, and the daughter survived. Strangely, the wife's soul inhabited the daughter's body, while the daughter's own soul was nowhere to be found.杉田平介 (played by Sasaki Kōnosuke) was unsure whether to feel grateful or sorrowful about this outcome. Thus, 平介 and the body of his daughter, but with the soul of his wife,杉田藻奈美 (played by Shida Mirai), began a peculiar life together. The wife decided to live well for her daughter, diligently studying to be a high school student at school, while at home she managed life as 平介's wife. For 平介, having both a wife and daughter by his side was somewhat comforting; however, at the same time, he could not have a normal married life with his wife. On the daughter’s side, now in college, she met different people and had suitors. On one hand, she wanted her daughter to experience an exciting life, but on the other hand, she felt guilty towards her husband. This caused both藻奈美 and 平介 great pain. In the end, the daughter made a decision that would help both of them find release... This drama is adapted from the novel of the same name by Higashino Keigo, which also has a film version.
