Twenty-two-year-old Sumire is in love with a woman seventeen years her senior. But whereas Miu is glamorous and successful, Sumir is an aspiring writer who dresses in oversized second-hand coat and heavy boots like a character in a Kerouac novel. Surprised that she might, after all, be a lesbian, Sumir spends hours on the phone talking to her best friend K about the big questions in life: what is sexual desire and should she ever tell Miu how she feels about her. Frustrated in his own love for Sumire, K consoles himself by having an affair with the mother of one of his pupils. Then a desperate Miu calls from a small Greek island and asks for his help, and he discovers that something very strange has happened to Sumire.
