The Little Bird Sleeps by the Sea manga features story and art by Yuu Minaduki.

Left devastated after the tragic death of his parents and sister, Yuuichi Tachibana adopts his seven-year-old nephew, Ayumu. Seeking a new beginning, he chooses to move them to a new house with a view of the ocean, hoping for a peaceful setting where they can concentrate on their healing.

There they meet Ryou Kurebayashi, who owns a neighborhood deli, and become regular customers. As Ryou and Yuuichi grow closer, learning about each other's unfortunately similarly tragic pasts, they begin to support one another - and Ayumu - day by day, building a little family of their own by the sea.
