So yes, you may have read the second chapter and have noticed the little boxes at the top of some of the sentences, well, this auxiliary chapter will help clear up that system.
Those little boxes you see are the "point-of-views of each of the characters."
Here is a simple explanation for that, so whenever you see it, you won't be confused.
■-■-■ = THIRD PERSON POINT OF VIEW
■-□-□ = TAKEMOTO NATSUO'S POINT OF VIEW (FIRST PERSON)
□-■-□ = KITAMURA EI'S POINT OF VIEW (FIRST PERSON)
□-□-■ = NISHIMOTO BENJIRO'S POINT OF VIEW (FIRST PERSON)
I hope this format of point of views isn't confusing to get used to, and hopefully this will help you understand the story!
