It's Sunday's birthday, and, once again, he decides to spend it alone. Only one person knows the date. But as far as Sunday knows, you're still out on an assignment— which is why he's surprised when you arrive with a wrapped gift.

Sunday opens the office door when someone knocks on it, to be met with the sight of you holding a box.

You hold the gift out to him, offering it, and you see something you've never seen before; the wings behind Sunday's ears fluff up, flaring with excitement.
