Young and Beautiful

I know this song is from the Great Gatbsy movie and I haven't seen it yet. But I feel like adding my interpretation from personal experience.

To me it's a beautiful and soft cry. It reminds me of longing for someone in the initial stages of a relationship, and sensing something from them, almost knowing something about them that prohibits you from believing in their love. Yet, you give in all the same without knowing. Almost convincing yourself "I know you will (be true)". The phrase "young and beautiful" is just an excuse, a fitting one, in the circumstances that shapes your limits with them as well as your hope in them. It helps you enjoy and live the moment (away from a truth you sense from them). That sentence "until I've got nothing but my aching soul" sums up how much hope she's investing just to love him. A cry of hope, almost to the Universe, to carry them through. She's trying to be positive for both of them because his attention brings her so much joy as if it's as genuine as it could get. It could be enough for both of them to escape into it forever. But that's the problem, they're escaping in every senese.. which is why she can't help asking till the end of the song "will you still love me?..." but there's no bitterness between them, as so much has been opened up and understood between that there is no room for bitterness. They understand each other. That's the blessing and problem. In her voice... you can almost here a positive hoping that the soul transcends and all will be right but at the same time that is what's sickening and draws them to the grave, each other... that sadness, lesson, betrayal. Those are the things that will make sure they will be. No other way is there a positive glimpse into the unanswerable.
