Faith (Korean: 신의; Hanja: 信義; RR: Sin-ui; also known as The Great Doctor) is a 2012 South Korean television series starring Lee Min-ho and Kim Hee-sun. It was broadcast by SBS from August 13 to October 30, 2012, on Mondays and Tuesdays at 21:55 (KST) for 24 episodes. It is about a modern-day plastic surgeon, who is kidnapped and brought back in time to the Goryeo period, 700 years in the past, where she falls in love with her kidnapper, a warrior who is the leader of the royal guard.^[1][2][3]

The title Sin-ui, can mean faith, as in belief in justice. The Hanja 神醫 means Divine Doctor, but in Hangul it also means divine healer or great doctor.^[4][5][6]

After King Gongmin of Goryeo (Ryu Deok-hwan) marries the Yuan princess, Noguk (Park Se-young), they return to Goryeo. On their way, they are attacked, and the queen is fatally injured. According to the advice of his royal advisor, the king orders the Captain of the Royal Guard, Choi Young (Lee Min-ho), to pass through a mystical portal ("heaven's gate") and find the "heaven's doctor". Choi Young travels to the future and brings back Yoo Eun-soo (Kim Hee-sun), a modern-day doctor from Seoul, to save the queen's life. He promises that he will return her to her world once she saves the queen, but the royal advisor schemes and persuades King Gongmin to force Eun-soo to stay as she can be useful to him.

As Eun-soo accustoms herself to her new surroundings, she and Choi Young gradually fall in love with each other. But problems arise as others become fascinated with her as the "Heaven's doctor", and Eun-soo becomes a pawn in the political power plays between King Gongmin, the Yuan overlords, the sociopathic nobleman Ki-chul (Yu Oh-seong) and Prince Deok-seung (Park Yoon-jae), King Gongmin's uncle. Constantly risking his life, Choi Young thwarts numerous attempts by Ki-chul and Deok-seung, who are out to have Eun-soo in their possession.

The series follows how Choi Young and Eun-soo evade and overcome impending problems and whether or not they succeed in getting her to heaven's door in time before it closes for good.

Faith was '90s drama queen Kim Hee-sun's comeback project, her first TV appearance in five years after her marriage and childbirth. The production of Faith was riddled with problems. The initial budget was 10 billion won (about US$10 million) but the series got its budget slashed, and was pushed back multiple times because of the leading actor. The drama was announced in 2009 with Lee Joon-gi as a main lead. However, the actor had to be replaced because he was drafted in the army. Born in 1982, Lee would normally have time to enlist until the end of 2010 but he received his papers early, shortly after beginning his new film project. This forced him to drop Faith, as well as his horse-racing movie Grand Prix, which had already begun shooting. Lee had tried to postpone enlistment to finish these two projects by the end of the year, but was unable to do so.^[17]

He was replaced by Kang Ji-hwan (Coffee House) who, however, had to withdraw after a request by the Entertainment Management Association because of his ongoing contract dispute and legal fight with his former and current management companies.^[18] The antagonist, Kim Seung-soo, also left, with the majority of the original cast at that time. This was a severe blow to the budget, as 10 million won had reportedly been spent on promotion with Kang as the lead.^[19] Actors like Oh Ji-ho and Lee Sang-yoon were considered for the main role, before finally deciding for Lee Min-ho.^[20] It seems that at that time the story itself was rewritten to some extent. A released trailer with Kang Ji-hwan showed a different atmosphere, much darker, more epic and dramatic than what was finally filmed.^[21]

Filming for Faith began on May 24, 2012 and it aired from August 13 to October 30, 2012. The ratings were mediocre but rarely dropped below 10%.

On October 19, a little before the end, the news was published that Lee Phillip (who played Dr. Jang Bin), sustained an eye injury and had to pull out of the drama. The injury did not arise during drama filming, but because he was scheduled for surgery next week he would not be able to continue shooting. Many viewers agreed that "It's too bad that he leaves so close to the drama's finale without getting to be a part of it. On the other hand, it's both fortunate for the drama and a damn shame for him that he's barely a presence in the show to begin with, despite the setup hinting at a much meatier role".^[22]

The writer Song Ji-na uploaded the original script on her website and it was obvious that there were considerable changes in the final product, some of them because of lack of money. However, Faith had financial problems almost from its start and they did not finish after the drama wrapped. Six months after the end of its airing, many of the cast and crew of that drama had not been paid. The acting, editing, and producing salaries which had not been paid amounted to 1.7 billion won. Drama producer and direction Kim Jong-hak, whose credits include Eyes of Dawn, Sandglass, Daemang (2002) and Legend (2007), was accused of double-contracting the Faith OST rights (to two separate companies) in the fall of 2012 became the subject of a police investigation for embezzlement and breach of trust. Kim was sued in February 2013 under the charge that he had embezzled 2 billion for personal use and summoned by police for ongoing investigation. He took his own life on July 23, 2013, by carbon dioxide, in a gositel room.^[23][24][25] This tragic death and many of the "ills" of Korean dramas have been attributed to the outsourcing of production to independent companies which struggle to cover the exorbitant cost of writers and stars.^[26]

Faith was sold to 6 Asian countries including Japan, Indonesia, Singapore, and Malaysia, with 90% of the total pre-sales amount of ₩4 billion coming from Japan.^[27]
