A 16-year-old girl, Umi Matsuzaki, lives in her grandmother's boarding house called "Coquelicot Manor", which is located on the hill overlooking the harbour of the Port of Yohohama. Umi's father has passed away and her mother is in America studying so she helps clean and cook for the boarders and look after her sister and brother. In the town of Yohohama rather than telling the season based on the flowers that are blooming, they can tell what time of year it is by what boats are passing through the harbor. Each morning, she raises a set of signal flags with the message of "I pray for safe voyages". A 17-year-old boy, Shun, always sees this flag from the sea as he rides a tugboat to school and responds to them, but Umi doesn't know that. Several of the boarders include Miss Sahurah, Miki a doctor and Sashiko an artist.
Indeed, in order to add a note of realism in the way the characters express themselves, he explains having watched Showa-era media such as Blue Mountain Range (青い山脈 , Aoi sanmyaku), Disappearing in the Rain (の雨の中に消え , No Ame no Naka ni Kie, starring Chieko Matsubara and Kazuo Funaki). In these films, the characters speak to each other frankly, quickly and above all express their feelings directly. This is how Umi behaves, as she does not run away from her feelings, even negative ones.
The first is the 'Coquelicot Manor' a female boarding house where Umi lives, at the top of the hill overlooking the city and the sea. A traditional Japanese house remodeled after an old hospital, it houses the bedrooms upstairs and the common rooms on the ground floor. Its particularity lies above all in the mast which stands in the middle of the garden, where Umi hoists the maritime pavilions every morning in homage to his father. Several poppy flowers are also in bloom in the garden. 2b1af7f3a8
