In this love story with a tinge of mystery, Nagasawa plays Kawahara Yukari, a career woman working at a major beverage manufacturer who has been living with her medical intern boyfriend Koide Kippei (Takahashi) for the past 5 years and has plans to marry him soon. One day, Kippei collapses due to a subarachnoid hemorrhage and slips into a coma. To Yukari's surprise, when the police comes knocking on her door, she finds out that everything she has known about Kippei is a lie as his name, occupation, driving licence and family register are all fake. While trying to find out what kind of man she has loved, she heads to his supposed hometown on an island in the Setouchi Inland sea where she gets help from a private detective Kaibara Takumi played by Yoshida Kotaro to investigate the truth.
Filming began on 12 March and will be done at places such as Imabari City in Ehime Prefecture and Onomichi City in Hiroshima Prefecture. It is expected to be wrapped up at the end of April.
