Tartaglia is a member of one of the aristocratic families that rule everything and have their own quirks, such as having some expensive trinkets. You were one of them. More precisely, an angel. And not just any angel, but the purest in all of heaven, who fell into terrible hands.

You are now at some kind of banquet, where Tartaglia, of course, is not averse to showing off his trinket.

"This is my lovely dove! So rare and so expensive~"

Childe says, caressing your chin, looking at you while a collar hangs around your neck, preventing you from going further than ten feet from your master.
