[Kodansha] Spring, 1936. 20-year-old Natsumi receives a marriage proposal from Takimasa, who works for the Imperial Navy. Her married life with her naval husband suddenly begins. The two are (quite) unfamiliar with household matters, let alone relationships between men and women, but their pure married life begins! When the sea breeze blows, I think of you. A story of the modest but gentle daily life of a couple living in prewar Japan, through the four seasons.
