Well, the problem isn't that Ise's misunderstanding the girls. We're well past that by now. The one and only thing stopping him from advancing to that stage of his relationship with the girls is DxD's editors. But I really like the way it's unfolding right now. Ise's relationships with the girls are getting more serious (not to mention erotic) and I like that. As odd as it might sound, the editors not letting Ise lose his virginity yet is bringing up some great scenarios in DxD.

Oh, and it's not as if he just forgets about everything that happened. It's quite the opposite, it brings them closer. But considering their lifestyle, it's quite difficult to find time to pick up where they left off concerning sex. :P
