Accompanied by his friend Miyata, Sano returns to Izu, a seaside resort in Japan where five years before he fell in love with his wife Nagi.
Itchan and her older sister Satchan go to the house of their grandmother, who is currently in a nursing home. They start cleaning the house in preparation for its renovation, but gradually the two discover the subtle gulf that lies between them.
Aki and Naoko are childhood friends who are drifting apart as adults. Immersed in her family life, Naoko now has a husband and daughter; Aki, on the other hand, remains single and is on leave from work due to a personal crisis. The plot might sound familiar but it has never been told like this. The director Kusano Natsuka stages the interactions through an actors’ table-read and, as the lines are repeated, the scenes gradually develop into on-location conversations. Moreover, she repositions the dramatic peak of the story to the beginning: Aki has murdered Naoko’s daughter.
