King 2 Hearts (더킹2Hearts ) is a MBC Television series about a South Korean Crown Prince who falls in love with a North Korean Special Agent. Lee Seung-ki and Ha Ji-won star as the leading roles.
The King 2 Hearts is set in a parallel universe where modern day South Korea is governed by a constitutional monarchy descended from the Joseon Dynasty. Lee Jae Ha is a handsome yet materialistic crown prince who doesn't care about politics and bares total reluctance for being the second successor to the throne. Lee Jae Kang, the current king, tricked him into joining a joint military collaboration with North Korea as a means to help "make him grow up".
Meanwhile, Kim Hang Ah is a North Korean Special Forces Officer who is also the daughter of a North Korean military high command official. Both Jae Ha and Hang Ah meet at the joint military training, a crucial part in establishing friendly relations between the two separate countries. Although the two met each other with a fiery disposition, Jae Ha unwittingly sparks a friendship with Hang Ah and soon, he subsequently falls in love with her. Soon, an arranged marriage is set up between the two and they eventually become engaged. While they attempt to set their differences aside and kindle a growing relationship, things suddenly take a turn for the worse when King Jae Kang and his wife were coldly assassinated by the devious Club M, who are led by John Mayer/Kim Bong Gu, a mysterious magician who wishes to remove the Royal Family and rule in their stead. Now crowned the new King of South Korea, Jae Ha must take the reigns and protect the country before it is too late.
The main Protagonist - The Crown Prince of South Korea with an assumed IQ of 187. A arrogant and irresponsible individual who surprisingly displays a lot of charisma. Unknown to many, Jae Ha chose to be an arrogant man due to his reluctance to take the throne. When his brother, Emperor Jae Kang, ascended to the throne, he assumed that he can live an indulgent "playboy" lifestyle for the rest of his life. As his two years of conscripted service comes to a close, he was unknowingly tricked by his brother into participating in a joint military exercise between North and South Korea, organized by the Emperor and the North Korean Military Command. King Jae Kang also used this an a opportunity to teach his brother a lesson and "help him grow up". However, his personality did not sit well with his teammates, who eventually saw him as a royal pain.
As a means to whip him into shape, North Korean Representative and Captain Kim Hang Ah "threatened" him into submission right after their first encounter. After a bumpy ride through each undertaken mission and a love/hate relationship with Hang Ah, Jae Ha eventually realized he had an attraction to the hard yet innocent female, a fact he constantly denied. Long after the completion of their training, a rumour "King Jae Kang once considered North Korean born Captain Kim as a potential candidate for Prince Jae-Ha's consort." was spread against the Royalty's wishes. As a means to stem the rumours and assuage the public, Jae Ha decided to publicly state that he is "indeed in love with the North Korean" to ease the political fire targeted towards his elder brother. He was subsequently engaged to Captain Kim Hang Ah and now must somehow transform their "Marriage of convenience" into a real romantic relationship. However, before any of that could take place, Jae Ha only found himself in a bigger mess after the assassination of the Royal Couple was announced. Now crowned the King of South Korea, he must act fast and be "mature and responsible" like his so called "old-headed" brother, before everything he cherishes in his heart falls apart. Faced with the possibility of his future wife being responsible or remotely related to the assassination, Jae Ha must now choose to trust his heart or his advisor. Heart triumphed over logic and the two found themselves growing deeper affections for one another throughout the ordeal. Even though so, public sentiments could not rest and continual accusations unto Jae Ha's bride comes in waves. Succumbing to clever deceitful persuasion from His (the King's) most trusted old advisor, Hang Ah was forced to go on public persecution.
Jae Ha never once known to care for another being in his life didn't sense how much the persecutions were straining Hang Ah and his relationship. His lack of display of concern was wrongly translated as being un-bothered and un-caring which deeply hurt Hang Ah. Harsh words were spoken against him and Jae Ha being the immature and egocentric self he is ordered for her exile back to the North. All seemed to be lost in this relationship, Jae Ha seeming complacent and proud of his decision, not till time in separation brought him to terms with his own true feelings. Regret and remorse stemmed his very soul during these times but with Hang Ah far-away in the North, out of reach and sight, there is little hope for reconciliation.
The timing could not have been worse when a public news report came from The North reporting that Hang Ah suffered a miscarriage. Jae Ha's is now faced with a rotten name for a King who's not only an irresponsible and selfish person but a sex maniacal monster. In spite of the horrible accusations, Jae Ha can only think about how hurt and pained it must be for Hang Ah and immediately devised a plan against his adviser's wish.
All great men have their sidekicks and this came to be no other than Eun Shi Kyung who's loyalty would surpass familial relations. With courage behind their back, King Jae Ha heads North and crosses the borders with his life at stake. All this won him a chance meeting with Hang Ah but did nothing to impress her or soothe her wrath and pain towards the loss of her child. His 'clever and heroic' ways were scoffed by Hang Ah who believes with all her heart that he only knows to look good but it won't do for her, as her heart will never change for him again.
Though grossly misunderstood, Jae Ha insistently stayed in The North, knowing many enemies are after his head in the hope Hang Ah will believe in him again.
