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. 
It's time for the national health exam at Itan High, and the excitement of eye exams and height measurements has fanned the flames of competition for the unremarkable Makeru Yadano. She's determined to beat the class idol Komi in the health test, and Komi's total obliviousness to their impassioned duel just feeds Makeru's determination. As the epic battle heats up, how will Komi handle her first rival when she's barely made her first friends?!
