Plot:
Mugi Tadano is a 16-year-old boy who lives alone; his mother died years ago and his father is always on frequent trips as a photographer. When his first girlfriend, Hinako, leaves him for Tokyo, he is understandably heartbroken. Kazuki, Mugi's best friend, invites him to work with him at his aunt's beach-side inn, in the hope of helping him shake off his depression. But things take a fateful turn one day when, while at work, he spies on a beautiful girl, Yuu Tsukisaki, changing clothes in an alley behind the inn. Yuu, instead of getting angry, charges him ¥120 (approx. US$1.05) for watching her. This isn't the last that he would hear from her, though, as the next day Kazuki sets him up on a blind date with none other than Yuu. They proceed to have a great time, but a great misunderstanding (and a sign of things to come) rears its ugly head when Mugi walks in again on Yuu, this time who is currently having a bath. Later, Kazuki tells him that she's taking the earliest ferry back home, seemingly agitated, Mugi runs to the harbor with the intent of trying to prevent another relationship from being nipped in the bud, she is long gone. Dejected, unsure he would ever see her again, he arrives home to get ready to search for her, only to discover that Mugi's father had allowed Yuu and her younger sister to live with them, because their father, who was a friend of Mugi's father, had died.
