Relationships in medieval times were different. I'm sure you didn't collect "ex boyfriends" then. Nor there were "dance contests".
And I'm sure then, teens were not breaking off every three days and getting together again, which I expect to be your next "great story"
Oh, and vampires were not sparkly, if you were about to add them to your idea.
