In the winter of 2012, two bodies wash up on a beach, victims of a lovers’ suicide. One is an actress, the other a director of pinku eiga (erotic films); neither, it must be said, left much of a legacy behind. But the actress, Shoko Kirioka (Honami Sato), did have two previous partners, who meet for the first time several months later during the rainy season and proceed to get blitzed while reminiscing about their old flame.
