Crash Landing on You (2019)

• Genre: Romance, Comedy, Drama
• Starring: Hyun Bin, Son Ye-jin
• The Hook: A South Korean heiress accidentally paraglides into North Korea and is found by a dashing army captain.
• Why Watch: This drama is the gold standard for romantic chemistry. The stakes are high, the side characters (the North Korean soldiers) provide incredible comic relief, and the “will-they-won’t-they” tension across the DMZ is legendary. It’s a beautiful story of love transcending borders.

Guardian: The Lonely and Great God (Goblin) (2016)

• Genre: Fantasy, Romance, Melodrama
• Starring: Gong Yoo, Kim Go-eun, Lee Dong-wook²
• The Hook: An immortal goblin needs a human bride to end his cursed life, only to fall in love with her.³
• Why Watch: Written by Kim Eun-sook, this show is a visual masterpiece. It features one of the best “bromances” in TV history (between the Goblin and the Grim Reaper) and a soundtrack that still tops the charts years later. It’s poetic, tragic, and hilarious all at once.

Reply 1988 (2015)

• Genre: Life, Family, Comedy
• Starring: Lee Hye-ri, Ryu Jun-yeol, Park Bo-gum
• The Hook: Five childhood friends and their families navigate life in a small Seoul neighborhood in the late 1980s.

It captures the nostalgia of youth and the complexities of family love better than any other production. You will cry, you will laugh, and you will definitely suffer from “Second Lead Syndrome.”

• Starring: Cho Seung-woo, Bae Doona
• The Hook: A prosecutor who has lost the ability to feel empathy teams up with a warm-hearted police lieutenant to uncover corruption.

• Starring: Lee Sun-kyun, IU
• The Hook: A struggling young woman and a middle-aged man form an unlikely bond as they deal with the hardships of life.
