18 year old Tsubomi has a bit of a weight complex. After graduation from high school, she takes up a part-time job at a video rental store where she is introduced to another male employee, 19 year old Shiro, whose shifts always seem to coincide with hers. Shiro casually mentions that she reminds him of someone familiar. A few days later, while on duty, she bumps into a customer in one of the aisles. He leaves, but not without dropping his membership card, and Tsubomi finds out that his name is Nasukawa, and that he is an acquaintance of Shiros. Meanwhile, after a song for a commercial comes on, Shiro realizes that Tsubomi reminds him of a famous model in a commercial (her eyes, at least), who turns out to be none other than Tsubomis cousin...?!
