Koyuki Hikawa is a socially withdrawn student who keeps an emotional wall between herself and others. The only person she spends time with is her childhood friend, Miki Azumi. One day, Koyuki's quiet life is disrupted when a boy named Minato Amamiya inexplicably starts trying to break through her barriers.

The aloof Koyuki, the popular Miki, the overly familiar Minato and the laid-back basketball player Yota share an awkward, occasionally frustrating, yet wholesome student life.
An ensemble drama shaped by the crossed paths of youth is about to begin.
