The adolescent romantic drama story set on Enoshima island in Kanagawa Prefecture. It centers around five Japanese high school students who are too young to be called adults, but who no longer think of themselves as children.
Wakana Sakai once took music lessons, but she
withdrew from music after losing her mother. Konatsu Miyamoto is a
positive-thinking girl who loves singing and spends time after school at
the vocal music club. Sawa Okita is a spirited archery club member who
dreams of becoming a horse rider. Taichi Tanaka is a chronically late
badminton team member who lives with his college student sister. Win
just transfered into Wakana's class after 12 years abroad in Australia.
Music brings Wakana, Konatsu, Sawa and the others together into an
ensemble during their last summer in high school.
