So Issei was gonna be just a gentleman?

I think that was a good idea, because I think that's a common depiction of harem protagonists, the main character of Daily Life with a Monster Girl being one example.

The only character I can think of who's a pervert like Issei is the guy from Familiar of Zero, and that's still a bit different.
