Kim Eun-sook

Following the success of Descendants of the Sun, Kim Eun-sook wrote her next two dramas, Guardian: The Lonely and Great God and Mr. Sunshine for cable network TVN in 2016 and 2018. Both dramas held the highest average nationwide ratings recorded for cable dramas—12.955% for Mr. Sunshine, and 12.428% for Guardian: The Lonely and Great God—until the former's two-year long record was broken by The World of the Married in 2020.

Kim said she wrote the hero of 2013 drama He Who Wishes To Wear the Crown Endures Its Weight: Heirs (also known as The Heirs or The Inheritors, 2013) specifically for actor Lee Min-ho. He starred opposite Park Shin-hye in a Gossip Girl-esque trendy drama set in a high school populated by the uber-rich. Kim said the biggest difference was writing about 18-year-olds when her previous characters had been in their thirties and forties, calling The Heirs "a teen romance for grown-ups". She admitted that she utilizes clichés, "but all my previous works used plenty of cliches and were embraced by audiences. The key is making characters that are different, so the audience forgets the cliched setting. That's what I'm good at, and that is what I find fun. I want people to think, 'I've seen something like this before, but still this is strangely fun.'"

By this time, the writer-director duo of Kim and Shin had gained a reputation for making hits, and their projects attracted high-profile actors. In 2012, after 12 years of acting in films, superstar Jang Dong-gun made his television comeback in A Gentleman's Dignity. Jang said that Kim and Shin's involvement in the project influenced his decision. After repeatedly alluding to him in On Air, Kim confessed her "ulterior motives" that she had really wanted to work on a drama with Jang. She and the crew were so determined to cast him in the lead that not only was the airdate moved back from March to late May to accommodate his schedule, but Kim, in the hopes of getting him to take the role, lied to Jang's wife, actress Ko So-young that there would be no kissing scenes. Instead, Kim wrote racy and sexy scenes, as befitting what has been called a "40-year-old, male version of Sex and the City." The drama portrayed the humorous love lives of a group of close-knit male friends played by Jang, Kim Min-jong, Kim Su-ro, and Lee Jong-hyuk, and previous On Air star Kim Ha-neul played Jang's love interest.

In 2012, she received a Lifetime Achievement Award at the SBS Drama Awards.

A love story between the rich, arrogant and eccentric president of a department store (Hyun Bin) and a brave but sweet stunt woman (Ha Ji-won) whose bodies switch souls whenever it rains, Secret Garden (2010-2011) became one of the biggest hits of Kim's career. After writing six dramas, Kim said she "contemplated on whether to write a drama that benefits the world or one that will garner good ratings" and decided to "abandon the depth I showed in City Hall" (which recorded solid, if unimpressive, ratings in the high teens). Instead, she "made an easy, light drama for the whole family to enjoy on weekends," and intentionally wrote it "to be fun." Secret Garden won Best TV Drama at the 2011 Baeksang Arts Awards, as well as Best TV Screenplay for Kim, Best New TV Actress for Yoo In-na, and the Daesang for Hyun. Kim also won Best Writer at the Seoul International Drama Awards, the Korea Drama Awards, and the Korea Content Awards.

In City Hall (2009), Cha Seung-won played an elite deputy mayor with presidential aspirations who unexpectedly falls for an unwitting female government employee-turned-town mayor (Kim Sun-a). Though she left space in the script for Cha and Kim to ad-lib, Kim Eun-sook called it her funniest work. She said she used politics as a backdrop for the romance to show her idealism regarding public officials.

Kim's next drama, On Air (2008), revolved around four entertainment industry figures - a newbie TV director (Park Yong-ha), an established screenwriter (Song Yun-ah, as Kim's alter-ego), a diva actress (Kim Ha-neul), and her struggling manager (Lee Beom-soo), whose personal and professional lives intertwine during the shooting of a fictional TV drama. Filled with cameos and a gossipy, insider look at stars behind the scenes, On Air was a hit, and director Shin Woo-chul (in his fourth collaboration with Kim) won Best TV Director at the 2009 Baeksang Arts Awards.

Kim tried her hand at writing for the big screen in the 2006 melodrama Fly High (also known as Loving is Okay). Directed by Kwak Ji-kyoon, it starred Ji Hyun-woo as a high school student who falls for a girl with a terminal illness (Im Jung-eun). The film was a critical and box office disappointment, and Kim soon returned to her milieu, television.

Despite overseas shoots in Hainan, China, the conclusion to Kim's loosely named "Lovers trilogy" was simply titled Lovers (2006-2007). Based on the Lee Man-hee stage play Turn Around and Leave (that also inspired the 1998 film A Promise), Kim again cast Kim Jung-eun, this time opposite Lee Seo-jin, as they played a plastic surgeon and a gangster entering into an unlikely romance. Though not as successful as its predecessors, Lovers recorded solid ratings in the high teens to low-20s.

Kim chose another European setting for her next drama, Lovers in Prague (2005). In a gender reversal, Jeon Do-yeon played a diplomat in Prague, Czech Republic, who falls in love with a police detective, played by Kim Joo-hyuk. Kim Eun-sook said she wanted to feature a romance in which the woman's social status is higher than her partner, and wanted to make the social difference between the two main characters as extreme as possible by also making the heroine the daughter of the president of South Korea. Kim added, "Although some might say it is another unrealistic story, a drama is a drama. I just want to make people enjoy the fantasy." Jeon won the Daesang at the 2005 SBS Drama Awards, and Kim Joo-hyuk won Best TV Actor at the 2006 Baeksang Arts Awards.

Kim first gained attention when her television drama Lovers in Paris became a major hit in the summer of 2004, with viewership ratings averaging 41.3% and a peak of 57.6% (#11 highest rated of all time). The cast and crew flew to France to film several scenes in Paris and Nice, igniting a trend among Korean dramas for overseas location shoots. A Cinderella-like story of a cheerful, ordinary girl who becomes the housekeeper of a cold and suave businessman, lead actors Park Shin-yang and Kim Jung-eun shared the Grand Prize ("Daesang") at the 2004 SBS Drama Awards. Then at the 2005 Baeksang Arts Awards, Lovers in Paris won the following awards: the Daesang, Best TV Actress for Kim Jung-eun, and Best TV Screenplay for Kim Eun-sook and Kang Eun-jung. It also became popular internationally, and Kim Jung-eun was named Best Actress at the 2005 Asian Television Awards.
