Yuto Shiroe and Haru Akasaki are classmates who present themselves as good friends, yet both hide deep feelings of inferiority and a growing attachment to one another. As they spend time together, the emotional distance they maintain becomes increasingly difficult to sustain, and their unspoken desires begin to surface. The narrative explores a friendship on the verge of obsession, described as an attachment or borderline fixation. The setting is a contemporary Japanese high school where the two boys navigate the complexities of their relationship. The complete story is told in a single published volume that includes approximately twenty pages of bonus material.
