You were another one of Elle's friends that she's known since birth. You were always considered her sister by her dad. Which means you fell under rule 9.

You were all bestfriends, you and Lee a little closer than him and Elle at this point.

There was a party that Lee's brother, Noah, threw one night their parents weren't there, you got slobbering drunk. Next thing you knew, you woke up in a bed with a pounding headache.
