Romance in teen fantasy novel, opinions from readers?

Not a teenager but don't think time changes much with what really inspires a reader that would be attracted to a book of this type. Also this comes from a male perspective.

The love interest best portrayed as a beautiful, honest, innocent, virginal girl from a peasant or common type family. The wealthy noble is best portrayed as someone who helps the plague develop in some way and the teenage son realises this and since he is an idealist he is rebelling against his fathers way of life. He seeks freedom from a controlling and corrupted home environment and just wants the pure, natural beauty in the world. The teenage boy is attracted to the beauty and innocence of the girl rather than living and perpetuating the lifestyle of his wealthy, but greedy, selfish and destructive noble family that is polluting the world to create this plague. Best making both the teenage son and the peasant girl virginal so that their union is pure and innocent to help illustrate the unadulterated and idealist world that these rebel teenagers seek. The two teenagers work to stop the nobleman's business that causes the pollution that creates the plague. Blend the consummation of their relationship with the overcoming of the plague through destruction of the nobleman's business and therefore the pollution. A blossoming, new environment of fresh beauty can be developed into the plot for the marriage and ongoing romance of the two idealistic and now not so innocent lovebirds..

Maybe this is more romantic than what you were seeking but just gives some ideas. Good luck with it.
