Crowley is surprisingly gentle as he reaches out to pull Aziraphale into another kiss, this time lowering himself until he's sitting on the edge of his bed and tugging Aziraphale down to his level; gentle not because he's uncertain in any way¹ but because he's still in slight disbelief that he's here, at this point, with Aziraphale.

¹He's never been more certain in his existence.
