Mikiya Kokutou entrusts Shiki Ryougi with the care of his cat before departing for some time. Shiki is hesitant, but Mikiya leaves the cat with her anyway, leaving her to deal with her new furry companion. Unfortunately, the cat grows attached to Mikiya and longs for his return. Meanwhile, Ririsu Miyazuki visits the site where her close friend committed suicide, considering doing the same. She comes across Fujino Asagami, a classmate with a painful past who is visually impaired. Despite their differences, Asagami helps Miyazuki overcome her grief by reminding her of their shared loss. Two months later, on New Year's Eve, Mikiya opts to spend the holiday with Shiki instead of his family, which annoys his sister Azaka. In contrast, Azaka spends the day with her school friends. As snow falls around them, Mikiya wishes for Shiki's happiness above all else.
