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.

The culture festival might have been a huge success, but Komi and Manbagi are still reeling from the shocking discovery that they both like Tadano! When everyone goes to karaoke after the festival closes, the girls see a perfect opportunity to woo their crush. Too bad neither of them can sing!
