Oh My Ladylord (Korean: 오! 주인님) is a 2021 South Korean television drama starring Lee Min-ki and Nana. Directed by Oh Da-young, the series tells a story of romance between a man who 'does not' love and a woman who 'can't' love. It aired on terrestrial television channel MBC from March 24 to May 13, 2021, on Wednesdays and Thursdays at 21.30 (KST) for 16 episodes. It is available on iQIYI as "Oh! Master" with subtitles in multiple languages globally.Oh My Ladylord's average rating of 1.6% is the second lowest ever recorded for a Korean drama airing on a prime time slot on a free-to-air television network, with KBS2 drama Love All Play setting the new record low of 1.4% a year later in 2022. The first half of the twelfth episode of Oh My Ladylord drew a 0.9% rating, tying with the penultimate episode of Love All Play to become the second-lowest single-episode rating ever (KBS2 drama Welcome saw a lower figure of 0.8% in 2020). Additionally, Oh My Ladylord was the first full-length prime time drama on free TV to never have rated above 3%. Media observers have cited Oh My Ladylord as an example of the downfall of MBC, which used to be regarded as the "Drama Kingdom" in the 1990s.
