Should Have Been Mine - Best Friend's Brother, Age Gap, Secret Marriage

Who knew that weddings could be a place where you could get a second chance? Elijah and Charlotte have history that runs too deep between the two of them. Five years ago, Charlotte thought Elijah was her endgame love until he broke up with her out of the blue. Now five years later, they are attending a wedding and run into each other. The problem? Charlotte was Elijah's brother's best friend and childhood crush. The other problem? Charlotte and Elijah never told anyone about their two year relationship. Is it too late for them to have a second chance or has there been too much damage that can't be repaired? Oh, did I mention they are still technically married?
