Name the Drama HELP

Hello out there,

So I am trying to find a drama i watched a while back and I cannot remember the name. What i remember most is the ending: FL gets married to ML's brother by order of the emperor (aka ML's father). ML's brother forces himself on her after immoblizing her, but she is able to fight through it and escape. However FL dies in the arms of ML who barges in too late.

...if you know it or think you know it, I'm all ears (eyes).
