I had honestly thought the OP was just a fun thing, but I guess it really is going in an idol direction.
During the part where Zange tied up Nagi in the equipment shed, I kept thinking to myself DOUJIN WHERE THE BOYS COME TO RETURN THE EQUIPMENT AND HAVE A LITTLE FUN WITH THEM. That would be so awesome.
I think I can also forgive Jin for having so many babes around him. He's a cool guy so far.
SUPER-VERY-SURPRISED!
