Amari Is Always Together With Pleasant Friends

Our main character, a college student named Haru, has some…"interesting" tastes. However, all he wants is to be left alone to enjoy the things he likes in peace and quiet. Unfortunately, were he to get his way we wouldn't have much of a story on our hands, would we?

One day a friend of his sees the contents of a certain book Haru has… a book containing some pictures relevant to Haru's "interests…" and, due to a misunderstanding, throws it out the window! What are the contents of the book? Where did the book land? You'll find out when Haru goes to get it back.

Of course it won't be easy, and he might even have a life changing encounter along the way (all thanks to that very same book.)
