"For two girls to go walking, hearts bounding-is that strange?"
Adachi, whose thoughts about Shimamura grow stronger every day, and Shimamura,
who's not at all bothered by that girl's feelings. From an outside perspective, they
seem like a close pair, but Adachi wants to close the gap between her and Shimamura
even more. On that fateful White Christmas, what will they wish for? How will they
move forward?
