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.
I'm just challenging myself. 
Just challenging myself...
...أتحدّى نفسي فحسب. أتحدّى نفسي فحسب
Das ist nur ein Versuch.
Nur ein Versuch!
Esto es un reto para mí. ¡Un reto!
