Having lost her parents at a young age, Osumi was taken in by her uncle, who ran a shoe shop, and grew up without ever experiencing happiness or a sense of joy. Against her will, she was betrothed to a rough-mannered clog maker named Katsuzo, and she lived a gloomy life. Then one night, a stranger named Shinshichi suddenly bursts into her home, where she lives alone, and begs her to hide him. As she reluctantly takes in this man with a mysterious past, Osumi gradually begins to feel a flutter in her heart.
