The arranged marriage {S.B}

Sirius black was known resident fuckboy of hogwarts, that is up to the second term of his fifth year when he received a letter from his parents reminding him that he was still betrothed to one of his childhood friends (who was from a pureblood family of course). He forgot completely about her up until his parents told him about his soon to be wedding which would take place as soon as he turned sixteen after sixth year, and even though he didn't want to get married he couldn't help but feel guilty that he had been messing around with so many girls over the past year especially as he started to fall back in love with her through the past memories he had of them together when they were little.

Fiona Yaxley part of the noble Yaxley house and was one of the most famous witches in the wizarding world due mainly to her father being a famous duellist and her mother being an amazing astronomer. She did used to have friends, well one friend but they were split up a long time before she went to an all girls school in France now she just pretends to have friends while they are basically just a bunch of basic pure blood bitches which she secretly despises. Except for her best friend which transferred schools a year ago. Now her mother's dead and she's cast out as a blood traitor but she doesn't care; she has money and new powers to explore and no one to get in her way.
