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.

Summer is about to begin, and Komi would love to be able to spend the long, hot vacation days hanging out with her new friends. But even though she’s made great strides in her personal quest, she still has problems communicating. For instance, making phone calls is so anxiety provoking that it keeps her up at night. Thankfully, Tadano always seems to know how to help her calm down!
