I love Kakashi/Sakura slightly more, but this is totally my second favorite pairing, and I think plays much better in the manga than Kakashi/Sakura ever could.

but somehow I don't want to see this in the manga, because who knows how the hell kishi will write this. i mean, asuma friggin died, leaving kurenai. same thing goes for dan and tsunade. *sigh*

However, those are all second generation characters - Dan was part of Tsunade's tragic backstory, and Jiraiya and Asuma where both in the 'doomed mentors' role. I think relationships among the younger crowd would play out quite differently (ex: Hinata's still alive.)
