From Shinnen: Nagisa is a normal highschool student. For winter vacation, it's decided that they will go snowboarding. On the ski slopes, she watches a guy who is really good at the sport. She tries it out, but gets herself into a little accident, causing her to return to the lodge. There, she meets Soushi, the guy from before. It's her chance! Will she somehow be able to ask Soushi to teach her?
