Japan was in the midst of a record-setting cold wave. My city - Uetsuruto - was no exception, as we were beset by day after day of freezing weather. Then, one night, I received a text from an unknown number.

"Look outside your window! Snow! It's snowing!"

Sure enough, the world outside my window had been transformed into a white wonderland.

"I'm sorry to text you so late. It's just... You were the first person I wanted to tell."

That was the final message they sent me. I had no idea who the sender was. Yet I had the strange feeling that, very soon, I might just fall in love.

In a world of snow, a warm and gentle love story is woven.
