forgotten OG historical / fantasy

not many details to go off but the manhwa had

- forgotten royalty marrying ml
- ml was known to be like bad shit crazy
- everyone thought fl was going to get killed
- there was something with a dragon

I believe the fl was. one from a maid and had no one taking care of her and then she was given to ml to marry cs her dad didn’t want to marry off one of his more valued daughters, she decides she’s going to survive and like kinda acts crazy to match mls crazy this is also like an older manhwa that’s most likely completed
