Helping a high school girl who was injured in a minor sidewalk accident at the beginning of December also marks the beginning of a new chapter in Air's life. The girl says with all seriousness that her mother taught her that when someone treats you with kindness, you must reciprocate. "Can you please allow my mother to treat you to a meal as a thank you?" If Air hadn't accepted the invitation, she would not have been able to find a new home right now, and her year-end celebration would have been the same as it has been in the past few years. Three years have passed since the person who used to love her was by her side. It's been three years that the month of December has engulfed her heart with loneliness. In the midst of joyous celebration, the feeling of isolation that she experienced as a result of the loneliness caused her to shed tears. However, this December, the life of the woman who still can't move on from her ex-lover is undergoing significant shifts. And the most noticeable shift is... … this Christmas, she doesn't have to celebrate by herself, thinking about Pure, as she has been. "It would be our pleasure to have you join us for Christmas if you have not already made arrangements." This year, Air will have someone to celebrate Christmas with.
