Two love one, one loves two. (Fred and George Weasley x reader)

Sirius Black has a one night stand when he was drunk. And that led to him having his own baby on a door step. When the mother delivered their child to his door step, he took her in and raised till the age of 3. He named the little girl, Y/n Lilly Potter Black. Y/n had magic within her since always. To be exact she was a Pyrokinesis. Y/n also loved the potters especially baby Harry. He was her favourite. Y/n heard of Voldemort and wanted to protect Harry, he was like her own baby brother, she put a part of her life into him. She didn't create a Hocrexes but it worked like one. If Harry was tried to be killed a part of her would die...and he would live. When she did that the potters and her father were amazed by the little child. But when the potters were killed her father and she knew who betrayed their family. They went to find Petigrew. He got 'killed' but both of them knew he was alive. When that happened Hagrid came back and took the little girl to the Weaslys that then raised her as her own.

But what happens when Y/n finds love...very different and strong love, to two people...

But what happened when she falls for to mischievous red headed brothers and they fall for her?
