When September Ends

Summary:
Harry's green eyes slowly blinked open to stare blearily up at the ceiling overhead before turning his head to one side to take in the unfamiliar room in which he found himself lying on his back, lovingly tucked into a large and comfortable bed. The raven didn't have the slightest idea where he was; the last thing that he could remember was leaving the corner grocer near his house with the half-gallon of milk his mother needed in tow and setting off towards home. His head was muddled and his thoughts were confused.
The bedroom door swung open with a quiet creak and a man stepped into his line of sight holding a metal breakfast tray in his large hands. Seeing him awake his handsome face broke into a kind smile, dark eyes overflowing with love.
"Did you sleep well, my darling?" he purred, crossing the room towards him. "Have you any idea how much I've missed you, Harry?"
