I'd love recommendations of dramas or movies like The Love By Hypnotic in which the FL is sent to another kingdom as a political or peace keeping marriage to marry the royal ML. Any country is fine, happy endings preferred but I'll take a tragedy occasionally. Thank you for any suggestions!

Rebel Princess
Heart2King  - this is not per say a princess but it follows a similar logic. Girl from NK and guy from SK have to get married for peace but welp they don't actually like nor want one another. 

Truth or Dare - arranged marriage by a king (right groom, wrong carriage)
The Starry Love - similar settings like the one above, but xianxia
The Princess and the Werewolf - princess is not sent, but kidnapped if that counts

edit: oh, sorry... you saw them already.

New Life Begins (C-drama)

Thank you, everyone! :)
