"Hey, shall we do it here?"
Arata, a new member of the "Erotic" Manga Club, has gotten used to the club's activities (reading erotic manga and "experiencing" erotic life).
The club president, Yuno, suddenly suggests, "Let's go on a date!"
Apparently, it's to thank her for always putting up with her "hobby"...
He ends up going on a different "date" with the cunning senior, Mamu, and the club president...
