Sleeping on the couch wasn't pleasant.
Severus kept moving to find a comfortable position, but to no avail.
Hermione had put a pile of blankets and pillows on the couch for him, and locked their bedroom door to keep him out. Actually hexed it, since he had tried to open it with magic but couldn't.
Laying in the dark, empty living room he realized he missed Hermione's body warmth and her soft body next to his.
He missed his wife. He had already decided, but being on the couch only made him more determined.
He stood up and creeped to the door of their bedroom.
