The second floor of the gym. That's our spot. Class is in session right now, but they don't hold class in a place like this. This is where Shimamura and I became friends. What is this feeling? Yesterday, I dreamed of kissing her. I'm not like that, and I'm sure Shimamura isn't either. But...when Shimamura thinks of the word "friend", I want to be the first thing that comes to her mind. That's all.

"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?

Adachi and Shimamura are now in their second year of high school. Luckily, they're in the same class this year, but Adachi doesn't seem too pleased with the fact that Shimamura is having no trouble fitting right in with their new classmates. Acquaintances, friends, best friends-those are all well and good, but how do you take that final step? Maybe having a sleepover and sharing a bed together...?

February 14th, a day like any other. But for Adachi, it's a huge deal-it's Valentine's Day, and Adachi's prepared her best chocolate for Shimamura ten days in advance! Now all that's left is to give it to her, but Adachi can't help but hesitate as the moment draws near...
