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. Now that Komi and Tadano are an official couple, Komi's dad wants another chance to bond with his daughter's boyfriend, this time on a sauna date! It's just as awkward as it sounds, but Tadano manages to make things even more cringe when heat-induced delirium prompts him to ask Komi's dad the worst question in the history of questions--how do you kiss a girl?
