(Volume 1) The second year of junior high, when most students are in the throes of puberty and feeling the pangs of first love. It's no different for Kanata Tanaka and Kazuki Yoshikawa, a girl and a boy who have been friends since elementary school. But even though Kanata and Kazuki are at the same point in life as their classmates, an air of adulthood sets the two apart. Kanata is taller and more attractive than the other girls, but the boys stay away because she seems too mature for them. Kazuki too stands out from the other boys, but the girls are wary of him because he seems like a player. And so, Kanata and Kazuki are thrown together in a charming, bittersweet tale of two very adult students falling in love like the teenagers they are.
