The journey to 100 friends begins with a single conversation.

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.

With Tadano's loving encouragement, Komi is spending her final year of high school slowly expanding her comfort zone. Volunteering to be the class president, resolving to win the sports festival, even talking to strangers-is there anything Komi can't do?!
