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 Golden Week, the Komi family is ready for adventure and a recently renovated resort is calling their name! And they aren't the only ones lured by the prospect of go-karts and camping-the Tadano family and their tagalong Najimi are there for some fun too. But when a sudden storm strands Tadano and Komi in a deserted cabin, things turn serious. How will they avoid catching colds with only one blanket to warm them?!
