Marryed to gray??

(Copywrite) Lucy and juvia are getting married on the same day but Lucy and juvia have switched rolls in weddings! Lucy is now marrying gray and natsu is now marrying juvia! But the only person who seems to notice is Lucy! What will she do? Does she eventually fall in love all over again with a new person or does she stay faithful to natsu? (Storyline is mine but I do not own fairy tail or the characters in this story)
