sae's arc is the funniest of them all~ and this time he gets to be the senpai. He needs to be tied with a leash due to her submissive personality

the narrator gives something new to the getting dull episodes...hes funny so heck why not. He voices out what the characters are thinking sometimes..and with Sae's quiet character...he becomes useful..it's like listening to a commentator with a serious tone who jokes =D
