You were the sworn enemy of George Fabian Weasley, why? just because your father was none other than Sirius Orion Black and Sirius was in Azkaban - because he was a "criminal" - Nevertheless, you were the bestfriend of George's twin, Fred Gideon Weasley, since first year.
Even now, in seventh year, George still hated you even after he knew that your father was innocent. In sixth year, you and George shared a little kiss at the Black Lake, you both didn't know why, it was so sudden.
It's all started after George, in sixth year, said that he hated you and saying horrible things about you to his friends, George was just angry that everyone thought he loved you.... Even if it was true he's too stubborn to admit it.
George was apologizing at the Black Lake, you were there too. In no matter of time, you both shared a closed lips kiss. But after that kiss, George was angry at you, all the time now.
George just thought that you didn't liked him like he does and just kissed him for fun. And now... In seventh year... A heated argument started by the Black Lake.
"You don't even love me! You just kissed me for the sack of your own fun! You didn't ONCE think of my feelings!"
George yelled at you, you never saw him like that it was caughing you off guard. His fists were clenched, a vein on his forehead breathing heavily. After some seconds that seems like hours, you finally spoke, your voice as soft as honey.
"George..."
You whispered softly, your voice calmed George instantly, his breathing showing down, his fists relaxed, the vein on his forehead disappeared as he looks at you with soft eyes. Looking at you like you're the only star in the sky.
