What couple from another TV show or Movie do you think DE most relate to?

Well I kinda think they are somewhat like Jack&Kate from lost in the case that both Jate and Delena had a lot of buildup. Jack told Kate he loved her first like Damon told Elena. Elena and Kate are both in a amor triangle. Elena is with Stefan First, Like Kate was with Sawyer first. Jack and Kate were only ever really a couple in like one episode in season 4. Damon and Elena may become a couple one day, IDK. Even though Elena and Kate are with other people, they still have this connection with Damon and Jack. Those are just a few of the similarties though. I really wanna here what couples you guys think DE can really relate to relationship and connection wise. =) thanks
