Ah! Wrinkling his nose at the touch of sweet and saccharine chocolate was inhaled, yes Aziraphale was most definitely here. Crowley would bet his tail on it.
The demon would have been pleasantly surprised to see Aziraphale so open to newer technology, let alone any social media. The angel always seemed to find comfort in the quiet, and here Crowley was making a good damned rukus already. However, it was almost as if he had been drawn here. Not only for the warmth, but there was more. Whatever more was. It wasn't really something demon's could explain, not with trivial words, anyways.
His ears easily picking up on the sound, a smirk touching his lips faintly. "Classic," Crowley quietly agreed on the choice of tunes. For a moment he stood there quietly in nostalgic pause, thinking back to the drives they've had together. Even that time that bloody crazy human hit his poor Bentley.
"Ngh," said Crowley. Suddenly ripped from his quick reverie with the smash of porcelain against the bookshop floor. Glancing down to Aziraphale's feet where his mug laid in several pieces and the spill of molten chocolate and cream. Ohshitohsitohshit "Uh (Whoops), did I startle you, angel?" A hesitant and faltered smile.
Crowley knelt down and scooped up the sticky pieces, a little demonic intervention and it was all mended. "Er. Good as new. Hmm?" No big deal. Right? Right. The demon handed Aziraphale the winged mug. "Do try to hold it this time?"
