you and fred weasley are best friends, and i mean you two are inseparable. however he seems to have liked you for quite a while now. he gets on your nerves in a good way. however you seem to have interest in another boy in your year which goes horribly wrong. so molly weasley invites you to xmas dinner, which fred tells her your dating. so then you have to fake date throughout this dinner, and for the next school year as his siblings now believe you are dating. but it seems it stopped being fake for both of you.
