Ron was rarely on time. And never early. But for Hermione, he always tried harder.
As he approached the door, Ron paused for a moment to organize his thoughts a little and straightened his hair a bit. Or tried to. As soon as his finger came off the button for the bell, the door was open and Hermione latched on to him. He returned her embrace with equal vigor and enthusiasm. She smelled nice. Hermione always smelled nice.
"It's good to see you! Good to be home." Ron flinched, hopefully unnoticed.
"I mean, London. This is your home. Not mine."
Ron could feel his face flush. It would definitely be noticed.
