In 1993, there was a happy family in a restaurant that used "Lin's rice bowl" as its signature dish. That night, three children secretly went out to watch the shooting star and escaped the tragedy of the family's destruction. When they came back, they found that their parents had been assassinated. In 2008, the eldest brother Arimiya Koichi (played by Ninomiya Kazunari Ninomiya) worked in a restaurant, but refused to make the family-inherited "Lin's rice bowl" for the guests again; the second brother Taisuke (played by Ryo Nishikido) and his sister Shizuna (played by Toda Erika Toda) rented a room in Tokyo. The lives of the three of them are a bit careless, which is the sequelae of the tragedy and the childhood of growing up dependent on each other. Seeing that the case litigation period will pass in November, the three siblings vowed to catch the murderer who killed their parents that year. They didn't expect that the biggest miscalculation came from their sister's love.
