The World of the Married remains to be the most-watched Korean drama in April as it beat the premiere of the highly-anticipated fantasy romance series The King: Eternal Monarch starring Lee Min-ho and Kim Go-eun.
The TV ratings of the two dramas cannot be directly compared because The World of the Married airs on cable channel JTBC while The King: Eternal Monarch airs on free-to-air broadcaster SBS.
However, data from Nielsen Korea show that the seventh episode of The World of the Married on April 17 pulled in 3.8 million viewers nationwide, which is higher than the 2.3 million people who watched the premiere of The King: Eternal Monarch on the same night.
In terms of nationwide ratings, The World of the Married obtained 18.5 percent, which is slightly lower than the 18.8 percent it achieved in the previous episode. Meanwhile, The King: Eternal Monarch recorded 10.1 percent and 11.4 percent, becoming the second drama in 2020 to obtain double-digit ratings on its first broadcast, next to Dr. Romantic 2.
Both dramas air every Friday and Saturday on prime-time.
The small decrease in ratings of The World of the Married can be seen as a result of The King: Eternal Monarch‘s premiere. The two dramas do not start at the same time, but since Eternal Monarch airs between 10 p.m. and 11:15 p.m. Korean Standard Time (KST) and The World starts airing at 10:50 p.m. KST, the broadcast of the two dramas still overlap.
Starring Kim Hee-ae and Park Hae-joon, The World of the Married is a psychological thriller about a successful doctor who finds herself navigating challenging situations after she learns about her husband’s love affair. The series already surpassed the peak ratings of Reply 1988, Goblin, and Mr. Sunshine and is now the third highest-rated Korean cable drama of all time. It is on track to become the third series in cable TV to exceed the 20 percent mark in viewership, following SKY Castle and Crash Landing on You.
Meanwhile, The King: Eternal Monarch tells the story of the King of the Kingdom of Corea, played by Lee Min-ho, who ends up in a parallel world where Korea is a democracy, similar to present-day South Korea. It focuses on his relationship with a feisty detective (Kim Go-eun) and their fight against those who pose a threat to their worlds. The series also includes Woo Do-hwan, Kim Kyung-nam, Jung Eun-chae, and Lee Jung-jin in its main cast.
