都会の高校から、海辺の田舎町にある七浜高校へ転校してきた小夏は、周囲にうまくなじめずにいた。そんなとき、七浜高校水族館部のひとり部員である小雪と出会う。小雪は周囲から高嶺の花と思われており、そのイメージ通り振る舞うことに、少し寂しさと息苦しさを感じていた。異なる孤独を抱えて、お互い惹かれたふたりは――?
Konatsu Amano is a high school girl who has just moved to a seaside town in Ehime Prefecture after her father is transferred overseas for his job. Lonely and unsure of her new surroundings, Konatsu finds herself gravitating towards Koyuki Honami, an older girl at her school who is popular but is seen as out of reach by her peers who view her as too perfect. Koyuki is also the sole member of the Aquarium Club, which in turn makes her feel cut off from others. In an attempt to help ease Koyuki’s and her own feelings of loneliness, Konatsu befriends Koyuki and the two gradually grow closer together.
