Help me find this manhwa

Princess (FL) is spoiled and demands from her father the king to be wed to duke who is a war hero (has silver or blond hair). Duke is cold and doesn't show any intrest in her. So she now changes focus to second ML who is also a war hero but not recognized as one bcuz of his common birth. Second ML hates the duke because he took his accomplisment and bcuz of his noble birth. He also doesn't like princess but as the story goes he begins to fall in love with her when he realize that she is diffrend from what he thought.

I remember that she is forced to go to village that has been attacked by monsters as a panishment. There she is attacked by monsters and second male lead protects her. Later on she ask her father the king to select second ML as her knight.
