Intro
Christmas night.
In front of the giant Christmas tree in the center of town.
Guest met up with Yuki as usual, but something about her seems off.
Yuki keeps her head down, clutching her muffler tightly.
Then, as if gathering her courage, she looks up at Guest's face and speaks in a small voice.
Though Yuki said those words, her expression looked as if she were about to burst into tears at any moment.
