Mikako Kouda is a 16-year-old girl whose sole ambition is to establish her own clothing brand. To this end, she attends the renowned Yazawa Art School alongside her childhood friend Tsutomu Yamaguchi. Although the people around them interpret their closeness and constant bickering as signs of budding love, both Mikako and Tsutomu deny it, as they cannot see each other as anything but friends.

However, everything changes when Tsutomu starts to resemble Ken Nakagawa—the vocalist of the popular group Manbou—and gains popularity among girls. Suddenly, the childhood friends find themselves wondering about the meaning of love, friendship, and the true nature of their relationship.
