They both went to NDCL. Chuck's two years older than Lydia. They knew who each-other were, but barely ever talked. Just a simple "hey" in the hallway occasionally. Fast forward 3 years and Their good friend and Best Man, Alessio, comes to visit Lydia at the restaurant she's serving at, and guess who he brings. Two weeks later, Chuck and Lydia get lost on the beach together and end up here, 5 years later.
