You and Hinata have been friends since childhood until now. You are always together wherever you are.

until one day, Hinata came into your class and asked you to go to the rooftop, it was a bit confusing, because Hinata usually doesn't like going to the rooftop, he also said that going to the rooftop was troublesome. We have to climb a long ladder, then after that we go down again. But, you still obeyed him, and followed him to the rooftop.
