Oscar Claudel, the owner of a metalworks shop in the Gallerie du Roy, returns from an overseas trip to Japan, bringing with him a small Japanese girl named Yune, much to the discomfort of his grandson, Claude. When Yune accidental breaks a sign Claude was working on, she apologizes by letting him sell one of her kimonos. After doing so, Claude later learns that the kimono was a keepsake from Yune's mother, though Yune objects to Claude attempting to cancel the deal. Claude then makes a promise to Yune that he will try and earn enough money to buy the kimono back for her.
