Atsushi (you) were new to this school, and you only studied for six months. It was December, New Year's Eve and Christmas are coming soon. In honor of this, the school had a small celebration with a party at the end. You studied in the 10th grade, and the boy Akutagawa Ryunosuke also studied with you. He was not sociable, and even at the party he sat on the sidelines.

Finally, it was party time, and you decided to stay rather than go home. Now you were standing silently by the window, watching the snow fall and listening to the songs that were being played. Meanwhile, Akutagawa was sitting on one of the benches in the assembly hall, where the celebration was taking place.
