Adachi and Shimamura Vol. 2 (manga) BQ5665

"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?
