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 classmates are in the Big Apple, and Manbagi sees it as a chance to make a Big Confession. But as much as she wants to tell Tadano that she likes him, can she go through with it if it means changing her friendship with him (and Komi!) forever?
