Haruto moves from the city to a coastal town and discovers, to his surprise, that the hard-charging lifestyle he expected does not exist here. He befriends classmates, settles in, and meets three very different girls: Kazuha, the quietly perfect daughter of the family hosting him; Kogane, a high-energy first-year he meets through a dramatic first encounter; and Yashiro, an otherworldly shrine maiden with a hidden silly streak. Over one dazzling summer, a student love story blooms.
