Obsessed Royal or Villain?

The Grand Prince is exactly what I'm looking for as an example. Also liked The Kings Woman for this reason. I'm basically looking for a royal or above the FL in status that is obsessed with her and will use force or whatever to get her {and she doesn't like him back} historically only! :) 

Loved:

• The Kings woman
• The Grand Prince
• Empress Ki
• 'Till the end of moon

Heard of:

- red sleeve but I dunno if that'l scratch the itch

- Mr queen, I don't like gender reversals like that

- trying queen for 7 days

Prefer Korean but will do Chinese too -- they're jus so long! Lol

• One and Only (SML)
• Colourful Bone (SML)
• Buried City to Shut All Lights (SML)
• Unchained Love (SML)
• Renascence (SML but in her first life she did love him before she realized how evil he was)
• Fighting for Love (ML, later on FL does love him at first but once he gets the throne he becomes evil)

Not obsessive or toxic or the kind of vibe I was hoping for.

Ah, that kind of obsessed.

Any other recs that are a little bit shorter than the Chinese ones?

Maybe Moon Lovers, ML threatened to kill his brother because his brother wants to marry FL.

Or ML in Queen Seon Deok (this one is long), he wants both FL and the throne so he's-half-forced-rebelling but you may think he's pitiful.

I may not watch enough Korean historical dramas. I can't think of others.
