A paragliding mishap drops a South Korean heiress in North Korea -- and into the life of an army officer, who decides he will help her hide.

'Crash Landing on You' offers a restrained romantic storyline, focusing on emotional connection rather than physical intimacy, which some find unusual. This approach is attributed to its conservative Asian audience. Despite the lack of passion, the series is lauded for its strong chemistry and subtle expressions. Some appreciate this restraint, claiming it deepens the romance, while others feel it lacks realism. The series balances this with frequent, albeit cheesy, love songs.
