Hurt/Comfort
Most days are good days now. A vast majority of them are filled with happy times and they're both better off without their respective head offices. Even with all that, it was hard to forget their previous lives.
Aziraphale occasionally goes to call head office at the end of the day when he's acting on instinct and following habit. And Crowley still half expects Hastur and Ligur to show up on his television. Why Hastur always choose to contact him that way, Crowley would never know.
There are bad days though.
Days where Aziraphale wakes up in a blind panic, clutching at his chest. When Crowley comes to check on him, a part of Aziraphale is mentally screaming that Crowley is in danger because of him
What will the demons to Crowley if they find out that he's with an angel?
What if Aziraphale never sees him again?
What if this was the last time?
It is strange that Aziraphale is never concerned about his own safety. Never terrified of the things that the angels could (and would) do to him. The way he saw it, Crowley's safety was always more precious to him than his own.
On those days, when everything feels so chaotic, the one constant Aziraphale has is Crowley. Crowley has a masterful ability to stay calm in such situations.
When the anxiety rises in Aziraphale's chest, Crowley is the one who reminds him to breathe.
Crowley is the one who makes him chamomile tea to calm him.
Crowley is the one who always stays, no matter what.
So, there are good days and bad days, but Crowley makes the bad days more bearable.
