Six girls, each living in a different city on the island of Hokkaido, each holding on to the same myth: that snow sometimes transforms into diamond dust, and a wish made on the dust is guaranteed to come true. A companion myth holds that a boy and girl who meet beneath the diamond dust are destined for happiness together. All six girls are navigating stubborn patches in their lives, and something in the snow and silence of Hokkaido is helping them find a way forward. When their paths eventually cross — and they do — things change for all of them, as the snow begins to fall.
