The lighthouse, cherishing the view of the ocean, hears stories from migratory birds from far away and feels the frustration of being unable to go anywhere. But one stormy night, the lighthouse shines with all its might all night long, and the ending, overflowing with pride and determination to live here, is moving, as it shows that everyone is shining a light on someone else. When we are about to be overwhelmed by a sense of helplessness, Saito Rin's beautiful story, which gently comforts our sorrow, is our "toudai," and that is why we will continue to encounter it again and again.
