Whew, that was a lot of preparations for the Grand Opening Day (thank goodness Sebastian found the perfect colour scheme for inside the shop - considering the kind of business Ciel is going to run, it certainly wouldn't do to have the customers' first impression of the interior design be anything but perfect).
Now back to his regular, almost manageable, workload. At least until there are any commissions. --Like the post says, anyone who wants to talk to Sebastian about those will be able to find him. Behind the hotel reception desk, at The Bakery, at school, walking briskly between any of those places...
The response to having had your entire life and memories rewritten is, clearly, to work more. Right, young master?
Speaking of which, there's probably a light knock on the door of whichever room Ciel is currently sitting in.]
