Sekai Meisaku Douwa: Mori wa Ikiteiru

Anya, an orphan living in a forest, is the subject of a story set during the Twelve Months. A princess, also an orphan, becomes fixated on a Galanthus after seeing a picture of it. This rare flower blooms in April but is out of season on New Year's Eve. In response to her desire, the princess makes a substantial offer to anyone who can bring her a bouquet of Galanthus before the winter ends.
