The main character of the story. He is a childhood friend with Umi Hayama. He cares about everybody that is in Tsugumi Dormitory, He tries to help everybody that is depressed.    He used to live with his grandparents. During the early episodes, Wataru lied to his grandparents that he is living in the boys dorm at the Tsugumi dormitory, but Wataru was the only person that was in the boys dorm so the school revoked the boys dormitory last year. Now the girls dorm is where everyone can live(including guys) that is from Takamidsuka senior high school. His Grandparents later on figure out that Wataru lies to them.    (Source: Wikipedia)

One morning, Wataru Hoshino found a sleeping girl - in nothing but her underwear - in his room. When she woke up, she quickly escaped by jumping out of the window, but not without punching Wataru in the face first. This girl, Rinna Sawaki, ends up being a transfer student of Wataru's school, as well as the new roommate of Wataru's dormitory. 
Wataru lives with four other girls and their school teacher, but due to Temizugawa Heavy Industry's cancellation of their aviation branch - South Sakojima Island's major company - the families involved with the corporation have to be evacuated in one year. As a result of this, the four girls have to leave the island in one year's time. 
Knowing this, Rinna refuses to become friends with Wataru and the other girls, because of the pain that she might experience as a result of their eventual separation. However, Wataru disagrees with her, and over the course of the year, tries to convince her otherwise.
