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 culture festival time! As third-years, Komi and her classmates can opt out of participating in order to focus on exams, but Komi (at Najimi’s instigation) convinces everyone that they should enjoy one last festival together.

Now it’s Komi’s job as class rep to make sure everyone works together to get their booth ready in time.

Can a girl with a communication disorder wrangle so many unique personalities, or will the culture festival turn into a culture flop?
