High school has just begun, and Imori, a first-year student with a naturally intense face and pierced ears, is already being avoided by his classmates because they find him intimidating. The only person who treats him like a normal classmate is Ichinose, the handsome, sociable, and endlessly helpful class representative. Noticing that Imori has trouble expressing himself, Ichinose offers to practice smiling with him. That simple act of kindness becomes the catalyst that closes the distance between them. The more time Imori spends around Ichinose, the more his heart races, and he starts to become acutely aware of his own feelings. But Ichinose’s attentiveness is not just general friendliness; his own emotions run deeper than Imori realizes, and as Imori gradually opens up to other classmates, Ichinose begins to show flashes of jealousy. The narrative follows the awkward but earnest progression of their relationship, from quiet moments of shared laughter to the confusion of first love. Along the way, Imori slowly sheds his isolation, learning how to connect with others, while Ichinose navigates the possessive pull he feels toward the one person he cannot stop looking at. The story is a gentle, heartwarming boys' love romance that focuses on emotional intimacy, innocent blushing moments, and the growing bond between two very different boys.
