The King 2 Hearts

The series' title, 'The King 2 Hearts,' deliberately echoed the sound of the sponsor Dunkin' Donuts, which drew criticism for the intentional resemblance.

The premiere was postponed by one week, from March 14 to March 21, 2012, because director Kim Do-hoon's previous drama 'Moon Embracing the Sun' had its final two episodes delayed due to the MBC general strike.

The show is set in an alternate reality where modern South Korea is governed by a constitutional monarchy descended from the Joseon dynasty, a premise unusual for contemporary Korean dramas.

Lee Yoon-ji won the Best Actress award in the miniseries category at the 2012 MBC Drama Awards for her role as Princess Jae-shin.

Jo Jung-suk received the '20's Booming Star' award at the 6th Mnet 20's Choice awards for his performance as Eun Shi-kyung.

The series was later rebroadcast starting February 18, 2019, on the newly launched channel MBC ON.

On April 11, 2012, the broadcast was skipped due to live coverage of the 19th general election results, and the show aired two consecutive episodes (7 and 8) the following night to make up for it.
