Mikako Kouda is a 16-year-old girl whose only goal is to launch her own clothing brand. For this purpose, she studies at the prestigious Yazawa Art School with her childhood friend, Tsutomu Yamaguchi. While those around them view their closeness and frequent squabbles as signs of a budding romance, both Mikako and Tsutomu reject this idea, seeing each other strictly as friends. However, the situation shifts when Tsutomu begins to look like Ken Nakagawa—the vocalist of the popular group Manbou—and becomes popular with girls. Suddenly, the childhood friends start questioning the nature of love, friendship, and their own relationship.
