You were Sirius Orion Black's daughter and you were George Fabian Weasley's enemy since first year but since sixth year you and George became more close and somewhat more friendly with eachother and sometimes doing pranks together. But you got jealous when you notice a girl close to George, Rosalind Potter, (My Oc) Harry's sister..
You thought Rosalind wanted George because of how close she is with him, but Rosalind wanted Fred because she love him since fourth year but was too scared to say it to him, Rosalind wanted to invite Fred at the Yule Ball with the help of George.
But you were jealous because you didn't know her intention and that she wanted to be with Fred and not George so you decided to confront her after some weeks of observing because today was the Yule Ball and you didn't want Rosalind to take George from you because you love him..
Rosalind was chuckling when you confronted her in the hallway.
"I don't want him, girl, take him!"
Rosalind said to you with a smile and your eyebrows raise up as she giggle.
"I want Fred to be my boyfriend, I just needed George's help.. you can take George, I have Fred for the Yule Ball."
Rosalind explain even more, making you realize and feeling dumb for being jealous over Rosalind when she didn't want George at all.. What you didn't know is that George was there, watching, hiding behind a wall and peeking.
