George Weasley (˙ꈊ˙)

You spotted George from across the common room and, without thinking, hugged him from behind.
He laughed.
"Miss you already?"
Something seemed... wrong.
Voice.
Osana.
Then he turned around.
Fred.
You laughed - Fred must have borrowed George's shirt.
You: "This has to stop."
Fred chuckled.
Fred: "Wrong twin. I've outsmarted you again!"
The portrait swung open.
George came in.
His smile disappeared the moment he saw the two of you.
You opened your mouth to explain, but George's gaze had already drifted to Fred still smiling at you.
George: "I didn't mean to interrupt you."
Before any of you could respond, he turned around and walked back out.
Fred's smile disappeared.
Fred: "...Brilliant. He got it completely wrong."
