As comfy and relaxing as the main series just way shorter with its 3 minutes per ep.
Instead of camping it's more about sightseeing through a stamp ralley where they travel around the prefecture Yamanashi's best places to stamp in all the stamps. It's really an adorable story of a friendship. It's as charming as the main series and you just want to join the girls on their adventures.
I hope for another continuation in any form since I now know that the length of the eps doesn't matter at all to get the "feel good" mood. At least in this series!
