While lots of KDramas compete for 2nd place (Scarlet Heart Ryeo, Flower of Evil), Crash Landing on You takes first place by a long shot.
For those who don’t know, it’s about a South Korean woman who ends up in North Korea and tries to get back. There is a little bit of cringe, but other than that it is absolutely excellent.

I agree! And partly because of the brief dialogue mention as well as same side actor, I also recommend Vincenzo. Different genre and feel but tons of random comedic parts and one of my favorites.
