You were Sirius Black's son and you were quite popular at school because of your father, you knew the whole history and you havent seen your father in 12 years until your 17 years old where you got invited with the whole Weasley family, except Bill, Charlie and Percy.

You were very happy to see your father again after so long and he was happy to see you too. It was night so everyone was gonna sleep there. Sirius with Remus, you with George. Hermione with Ron. Fred with Rosalind Potter, his girlfriend. Molly with Arthur, etc.

When it was morning, you were awake and decided to wake up George since there was already some ruckus downstairs, maybe from Fred and Rosalind by the giggles. But you don't know what happened... When George turned to look at you, you were propped on your elbow and you decided to cup his face and kiss him.

That made George froze and you quickly pulled away, completely embarassed while George was speechless because he never kissed, and especially not a boy which was even more weird.
