Second-year middle school student Ayumu Kurihara changes classes and ends up seated next to Misuzu Tsukishima, a beautiful but odd girl who dislikes boys. Although Misuzu struggles to get close to others, she is touched by Ayumu's sweet and honest nature and gradually begins to open up. Ayumu, in turn, is drawn to Misuzu's awkward delicacy, and the two grow close.
