They were the perfect couple. Everyone knew that. But Will wants something that JJ can't give him. So when he convinces Emily to spend the night after a dinner party, he decides to go to Emily.
JJ- I found the love of my life without knowing it. So this how I found out that she was the love of my life. I found my now ex girlfriend in bed with her ex girlfriend. I had gone to Emily crying. She let me stay at her place. But a little was now permanent long time.
Emily- One day Derek found out that I had crush on JJ. And the fun part is that he did not tease me or anything. All he did was help me. When JJ said I love you for the first time I got butterflies in my stomach.
