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.
Komi´s final year of high school is going great! She led her class to victory at the culture festival (i.e., their ramen was a hit and nothing burned down), and she´s getting close to her goal of 100 friends! But her younger brother Shosuke isn´t having the same luck. Recently a menacing new group led by Tadano´s sister has started to target him, and they´re determined to make him smile!
