Bishojo to Buratabi

I want to escape from my hectic daily life and travel! What if the most beautiful girl in school makes that dream come true?

A high school boy from Tokyo, Takahashi Shou, is fed up with his constricting daily life, and he decides to run away a journey. When he gets to the train station platform, he sees his classmate, Riho Nanase, also standing there, deep in thought. He asks her to come with him on the trip. She is skeptical at first, but eventually she begins to loosen up and enjoy the food and sights along the way.
