AU where Merlin is a secretary of a very successful law firm and Mordred is that grunge kid that hangs out across his flat.
He holds out until the last second, until the wind blows hard enough against the window that Merlin feels the cold seeping through the walls, and the snow slowly blankets thick layers across the ground and anything laying on it
It's past midnight when he leaves the half-drunken wine bottle on his counter and thrown on a pair of slippers before padding his way down the stairs to the bottom level of the apartment building, before pulling open one of the thick double doors.
He's sitting there, curled up on the stoop with a thin jacket wrapped around his shoulders, and for just a second, Merlin feels awful that he's been left out here for who knows how long. Mordred looks up when he realizes it's Merlin standing over him, and Merlin nods once, gesturing over his shoulder, and leaves the door open before heading back upstairs
Two seconds later, he hears the door close and Mordred follow
"Shoes off," Merlin says when Mordred finally catches up, slipping through his flat's door seconds before it closes. "Eat the leftovers in the fridge." He snatches the wine bottle off of the counter and glares. "Don't touch the alcohol."
"I can do that," Mordred says, inclining his head, heavy boots slipped off by the front door. "Thank you."
"Don't," Merlin mutters, and turns up the heat a few degrees. "I just know how it feels to be cold."
He leaves, heading towards the hallway and makes sure he doesn't look back.
