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's family is hosting a guest, and the standoffish Rei is really putting Komi's friendship skills to the test! But Komi sees a bit of her old loneliness in the child and won't give up on making a connection, even if she has to chase Rei all over town to do it!
