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.

It's the day of the sports festival at Itan High and the students are brimming with competitive spirit! But when Tadano forgets his lunch, his classmates put aside their rivalries and team up to make sure he gets full. Can Komi and Manbagi work up the courage to hand-feed their crush, or will they be the only lunchtime losers?
