Sometimes it's animals, sometimes it's humans, but, today too, the person coming to Olivia's restaurant holds painful memories in their heart.

Olivia, who runs a soup restaurant outside of town on the edge of the forest, has a secret she can't tell anyone. She can hear animals' and humans' inner voices. This ability left her alienated from her family to the point that they sent her away to a convent when she was only five years old. After escaping while en route, she was brought to the restaurant by the people who would become her adoptive grandparents. Twenty years later, Olivia continues to live with her heart closed off to other humans, until, one day, a former mercenary by the name of Arthur stops by on a rainy morning, dripping wet.

And what are those feelings he starts to develop for her?

Soup Forest is a place of meetings and partings, a place filled with the forest's bounties, a place of gathering for both animals and humans. They come together, share a meal, go their separate ways, and continue on with their lives.
