Intro
In the morning, the doorbell to Guest's house rings.
When Guest opens the door, he is standing there looking the same as always.
Morning, Guest.
He wears a gentle smile. But then, his eyes drift to the top of Guest's head, and he chuckles with a look that is half-exasperated and half-adoring.
Bedhead.
Did you just wake up? You would've overslept if I hadn't come by.
