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 and slepping 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.
