On his return from a trip to Japan, Oscar Claudel brings a young girl named Yune to work at his metalworks shop, the Enseignes du Roy.

Yune eats her first French breakfast and attempts to hide her dislike of cheese! Claude, Oscar's grandson, takes Yune shopping.

Claude becomes inspired by Yune with an idea for a sign for a nearby music shop. Later, they find the owners of Yune's kimono.

Alice, the youngest of the upper-class Blanche family, becomes interested in Yune and wants her to stay with her, but Yune has made a promise to the Claudels.

Claude scolds Yune for her kindness, which is taken advantage of by a boy who steals from the shop.

Yune faints from a fever, which fills Claude with guilt for scolding her earlier. He receives help from Alice and her doctor to cure Yune.

A tea party at the Blanche's brings Claude and Camille together, while Alice shows Yune the nursery where she grew up.

Claude speaks about the past with Camille when they used to play together in the Blanche's family garden.

Oscar spends time with Yune and Alice. He shows off a slide projector that reminds Alice of her parts of her life back in Japan.

Alice invites Yune to an exhibition at the Grand Magasin, but Claude opposes and makes other plans for them. Yune shares more about her family in Japan.

Yune goes out to search for a lost black cat and gets lost, which worries Claude who cannot find her.
