Kdrama Suggestion!!! - Crash Landing on You...

A South Korean heiress, Yoon Se-ri, gets caught in a storm while paragliding and finds herself blown off course into North Korea. Se-ri then runs into Ri Jeong-hyeok, Captain of the North Korean Special Forces and a member of the North Korean elite family. Captain Ri eventually hatches a plan to get Se-ri back to South Korea with the help of his squad, but not before they all tackle the obstacles that come their way—and then some. This drama mixes romance with comedy and ultimately tells the tale of two star-crossed lovers. It's currently the highest rated tvN drama and the second-highest Korean drama in cable television history.

(Also, stars Son Ye-jin and Hyun Bin have since gotten married and are expecting a baby!)
