At night the darkness is illuminated by 3.7 million glistening lights, and lovers huddle together in front of them. However, there is a rumor about it- lovers who see this illumination together would go their separate ways. Yoko and Takanori are no exception. Their relationship is changing day by day.

So in this city, memories are falling as snow.
