Shitty mom discovers her daughter's relationship with the "dirty commoner girl", sells her out to the cops.
Young cop gets a hold of her, bla bla yadda yadda "you're mine now" type of possessiveness he mistakes as love.
Forced marriage/pregnancy, she dies (maybe in childbirth), guy blames daughter for her death.
This is my prediction too, I don't see the 'commoner' ending up with the noble girl with how the mom is, nor do I think she will willingly get with the cop (but damn what do I know)
