Since kindergarten, Shun, Kaname, and twins Yuuki and Yuuta have been friends. It's unclear if they truly like each other or not, but they continue to spend time together in high school. Their group has welcomed a new half-Japanese transfer student, Chizuru, who brings some energy to their routine. The manga follows their everyday activities, which are not particularly thrilling but do offer a peaceful and occasionally amusing look at youthful companionship.
