Socially anxious high school student Shoko Komi's greatest dream is to make some friends, but everyone at school mistakes her crippling social anxiety for cool reserve. Luckily she meets Tadano, a timid wallflower who decides to step out of his comfort zone in order to help her achieve her goal of making 100 friends.

Komi and her friends are going on a ski trip! Who cares if only some of them actually know how to conquer the slopes. The point is to have fun and show off their winter fashions! But things take a turn for the awkward when Manbagi and Tadano get left behind and have to spend the night in snow country. The only inn around is expensive, but worse than that, there's only one room!
