The world is so big, with so many longitudes and latitudes. They were running in their own dimensions, but they had an intersection at a certain moment.
Most of it is a chronicle of the protagonist's sophomore year in high school. It strives to restore the atmosphere of youth, but in reality it is sugar water (bushi). The plot develops according to time, interspersed with appropriate flashbacks and a little selfish song recommendation. It is the joy of high school students in their hardships.
Good luck in the college entrance examination, boys! ! ! ! ! !
Intention: Longitude and latitude do not exist, but you exist, and that is enough.
