The journey to 100 friends begins with a single conversation. 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. Najimi's sudden declaration of a Christmas Eve party at Komi's house sends the friends into a flurry of last-minute gift shopping and Komi into a fit of worrying. But when her friends all turn up with good cheer and a giant stuffed animal for her, it turns out Najimi wasn't just being impulsive--there's a special surprise for Komi too!
