Nagomu is laid up in bed with a cold, and as his consciousness grows hazy, he remembers a senpai from his school days who went off to Tokyo to chase a dream.
That night, as Itsuka tends Nagomu, she glances up through the window and sees snow fluttering down.
Snow on the day before Valentine`s Day. Seeing the snow piling up on the ground, Itsuka is reminded of the day when she was first left in the people of Ryokushou`s care.
Itsuka doesn`t have good memories of snow. Nagomu makes some new ones with her, building snowmen.
