The most ordinary story: Once upon a time there were the Minami sisters, three Japanese schoolgirls – the eldest, sensible Haruka; the middle one, unbearable Kana; and the youngest, cunning Tiyaki. Every day they went to school, cooked food, watched a series, and interacted – with each other, friends, and girlfriends. Schoolwork, tardiness, first love letters in the locker boxes, pranks, misunderstandings, funny nicknames, and absurd competitions… In short, idyllic school routine.
