The story centers on Koyuki Hikawa, an aloof high school student who has a hard time getting close to others, and who builds a wall between herself and other people. Although she spends her time alone at school, for some reason Minato Amemiya keeps getting closer to her. The frustrating story of youth follows the lives of four somewhat complicated individuals: Koyuki and Minato, plus the popular girl Miki and the laid-back boy Yōta.
