Mikoto Shinozaki is a high school student who lacks social awareness. Furthermore, because of his messy appearance and low self-esteem, he becomes an easy target for bullies. Nevertheless, any misfortune that befalls Mikoto is partly his own fault—at least, that is what Yuki Fukuzawa, the most popular girl in class, believes. Based on this assumption, Yuki invites Mikoto to join the school's bicycle club, hoping he can improve himself and make new friends. Driven by his feelings for Yuki, Mikoto has no reason to refuse her offer—except for the fact that he does not know how to ride a bicycle. Despite lacking even the basics, Mikoto cannot shake the image of himself on a bicycle. Eventually, he gives in to his curiosity and sneaks onto the school grounds at night to practice. This marks the beginning of Mikoto's journey as he pedals through the vast world of cycling, where the scenery of his life changes in ways he never thought possible.
