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. [Translated from Official Summary]
