The original manga follows the relationship between old-fashioned and domestically minded high school girl Mai Nanase and her brother's friend, the innocent late bloomer Souta Nishino. Mai and her brother's room are adjacent to each other, with thin walls that allow them to overhear each other. The story begins when one day, she overhears Sota telling her brother that he finds her cute.
The upcoming drama adaptation is set to premiere this March, while the previously announced film will premiere this spring and is directed by Ryo Nakajima (Samurai Rock) with scripts written by Chieko Nakagawa (Closest Love To Heaven).
