Until now, I had no interest. I pretended not to care. I didn't expect anything from anyone. But this year is different. The first Christmas gift I wish for is to spend Christmas with Shimamura. Until now, I spent every year without a thought. I wasn't particularly interested. But this year is different. I started to think that I should put some thought into choosing a Christmas gift for Adachi. The high school girls, Adachi and Shimamura, who were living their unchanged daily lives, begin to subtly shift their relationship.
