He says, "Not really an ending, but a good place to stop for now." Sounds like a decent show for a queue.
UPDATE: Chris Beveridge has more:
In the end, nothing is really resolved, which makes sense, as the manga’s been running for several years past the point where the show ended. We never find out what makes Urabe so “mysterious,” so those hoping for a final reveal will be disappointed. But in the end that’s really beside the point. It’s been a relaxing, sweet, nostalgic slice of life show, with a bit of supernatural psychic powers to add a twist. The choice to use drool as the catalyst for the supernatural is a questionable choice, but what’s done is done.
