Simply, I'm sick of Cinderella stories. Why does the nobility always have to be the ml? And why does the fl have to be some random, ordinary girl who catches his eye? Of course, not all stories run this course, but it's still painfully common.
Are there any about a princess? Extra points if her love interest has a really humble background.
It doesn't need a happy ending, because when is there ever a happy ending between a princess who elopes with a nobody - although that could make an interesting story. Princess elopes with her love when they're young, impulsive and ignorant, experiences the harsh reality, regrets it, but needs to grow up and come to terms with her life decisions. Unfortunately, I don't think that exists.
