|| Old Friend || Xiao x Reader

There are various ways to check if a certain individual is immortal.

You can observe them for years to see if the progression of time have carved their way into their features. Maybe cut them yourself and see if they bleed and heal in the ways as a mortal human ought to. Or perhaps just ask if they're the none-secretive type.

And the look in your eyes had defied all logic.
