3 years on from hospitalité, Kiki Sugino and Koji Fukada are back again with this socially-conscious film about a 18-year-old girl in-between adolescence and adulthood who spends a summer in a valley and enjoys romance. Sakuko, a 18-year-old girl studying for her university entrance exams, decides to accompany her aunt Mikie on a trip to a seaside town. There she befriends Takashi, a refugee from Fukushima who has dropped out of high school and works at a motel run by Ukichi, a friend of Mikie. In-between childhood and adulthood, Sakuko starts to understand the difficulties of becoming an adult.

High school student Izumi Kawashima, whose daily routine is rating newspaper articles, finds a wallet containing a large sum of cash. Instead of returning the wallet to its owner, Izumi decides to lend a substantial portion of the money to a middle-aged male acquaintance. She eventually returns the wallet to its owner, a wealthy high-school boy named Koki, who notices the missing money, and as compensation, asks Izumi to do something for his friend - to create a newspaper that brings happiness to its reader.
