A member of the high school art club called Sakuko falls into the sea while sketching a boat. Witnessing the incident, Saibara creates a painting titled "Drowning Sakuko" and wins an award at a contest, leading the painting to be displayed at school. Moreover, Saibara takes the liberty of announcing that she will paint Sakuko for her next piece during a newspaper interview. Frustrated by the situation, Sakuko gives up on her artistic path and attempts to create a new work with the motif of a "boat" in her home, which is scheduled for demolition.
Shibuya Haruko is a high school student living in Tokyo. One night, she is instantly smitten by Kanagawa Kenichi, who is lying prone on a bridge. But Kenichi becomes far more interested in a girl he impulsively hits on, Mayumi, over the high-spirited Haruko.
