[This day has been special to him for a while now, for more reasons than simply it being his birthday. But the change in scenery (and everything else, to be honest) doesn't mean he should deviate from tradition, and so he's spending the morning and early afternoon first shopping for groceries (with money borrowed and not stolen, no matter what anyone says from Dou) and then cooking a wide variety of dishes-- and if they're mostly what he knows the ones he's cooking for prefer, well. It's no big deal, really.
Later on, he can be found setting a picnic in the park, despite the tables and food available all around him. Though he does stop to pick up a cookie, butterfly-shaped, staring at it for a long moment, eyes downcast.]
