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?

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.
