Nojima Satoshi is a photographer who wants to photograph scenery but currently works for a modeling agency where he takes picture of his best friend, a model in his 30, Shingo. One day, Satoshi decides that he no longer wants to put up with what he doesn't want to do, and sets out to go to Canada to shoot pictures of the Canadian scenery. Living next door is a woman, Nanao, also approaching her 30, who is too busy with her work at a flower shop to consider dating. One day, a man working at a convenience store nearby stops by her flower shop and confesses his feelings for her. Satoshi and Nanao know about each other's existence by the sounds their neighbor makes through the thin wall. Even though they do pay attention to the sounds next door, they actually have never met each other, or make any attempt to meet the other person. The movie tells two separate stories that happen in parallel and focuses on the lives of two people approaching their thirties, and the doubts they have about work, life, and love.
