Souwa has no friends. His sharp, cold eyes have always been a source of trouble, attracting only delinquents who want to fight, leaving him to live out his days in a cycle of brawls and pain. He hates the way people look at him because of his gaze. Everything changes when Kyoushirou, the popular and dependable vice-captain of the basketball team, approaches him. Kyoushirou is the direct opposite of the aloof Souwa, a senpai who is always smiling and effortlessly draws people to him. The first person to ever compliment the eyes Souwa despises, Kyoushirou describes them as so blue and clear that they look like they are shimmering.

The story follows the growing connection between the caring, handsome senpai and the clumsy, lone-wolf kouhai. Set within a high school, the narrative focuses on their developing relationship as Souwa tries everything to avoid what he sees as a glowing beam of sunlight in the form of Kyoushirou. Despite his attempts to push him away, Kyoushirou persists, seeing past Souwa's intimidating exterior to the vulnerable person beneath. The manga explores a heart-fluttering, pure romance between two boys from opposite social worlds. As Souwa slowly opens up, the story navigates the delicate process of trust, healing from a past marked by isolation and violence, and the discovery of acceptance. The complete, short narrative arc traces their journey from a chance encounter to a meaningful bond, culminating in a single-volume conclusion.
