Yuki and the summer snowflakes

Yuki was a shy 7-year-old girl living in a small town in Japan. One sunny day, she noticed strange snowflakes falling from the sky. Yuki ran to her grandmother, Obaa-chan, to tell her about the summer snowflakes. Obaa-chan told Yuki about a winter curse threatening the town. Yuki was worried but also curious about how to break the curse.
