More than just the storyline, we’ve all come to love the actors and the characters they portray in dramas. At times, their chemistry is so intense that we never get over them, and we hold out hope that they would be cast again in a new series.

While it seldom happens, it is possible for two actors to work together again in a new drama, which was the case for Guardian: The Lonely and Great God second lead co-stars Lee Dong-wook and Yoo In-na in Touch My Heart, Secret Love lead actors Ji Sung and Hwang Jung-eum in Kill Me, Heal Me, and Criminal Minds‘ Lee Joon-gi and Moon Chae-won in the recently concluded crime thriller Flower of Evil.

Over the years, we have witnessed a number of Korean actors reunite with previous co-stars in K-dramas. Let us look back on 10 of the most-loved reunion projects of some celebrities.

Lee Joon-gi and Moon Chae-won


Starring as the loving husband with a dark side, Lee Joon-gi reunited with Moon Chae-won, who played his detective wife, in the 2020 mystery-thriller series Flower of Evil. It centers on the married life of the characters and the secret that the husband is willing to hide from his wife, no matter what happens. Back in 2017, Lee Joon-gi and Moon Chae-won also starred in the crime series Criminal Minds as colleagues in a team of highly skilled profilers who track down criminals in order to solve cases. The series also featured stars Son Hyun-joo, Yoo Sun, Lee Sun-bin, Go Yoon, and Kim Yeong-cheol. Criminal Minds was a remake of the popular US series of the same name that first aired in 2005.

Lee Seung-gi and Bae Suzy


Gu Family Book is a 2013 fusion action-historical drama starring Lee Seung-gi and Bae Suzy. It tells the story of a half-beast, half-human in search for an ancient book that would help him become fully human. Seung-gi played the half-man, half-gumiho who falls for Suzy’s character, a martial arts instructor at her father’s school. Six years later, the two were cast again as lead characters of the action thriller Vagabond, which follows a stuntman on a mission to uncover the truth behind the plane crash that killed his nephew and seek revenge. Lee Seung-gi played a stuntman, while Bae Suzy played an NIS agent working undercover at an embassy in Morocco. The two cross paths and help each other uncover a more sinister conspiracy.

Ji Sung and Hwang Jung-eum


Ji Sung and Hwang Jung-eum first starred together in the melo-thriller Secret Love back in 2013. Ji Sung played the second-generation chaebol heir who drowns in his chase for revenge following his girlfriend’s death. Jung-eum, on the other hand, goes to prison for a crime after she takes the blame for the incident caused her boyfriend, who eventually betrays her. In 2015, the two reunited in the medical drama Kill Me, Heal Me, where Ji Sung once again portrayed a chaebol heir. But this time, his character has dissociative identity disorder and has seven different personalities inside him. In the drama, Hwang Jung-eum played a messy and short-tempered resident doctor who becomes his secret psychiatrist. Later on, Jung-eum reunited with Park Seo-joon, who played her brother in Kill Me, Heal Me, in another series.

Nam Joo-hyuk and Lee Sung-kyung


In 2016, both actors were part of the cast of Cheese in the Trap, which starred Park Hae-jin and Kim Go-eun. The drama follows the odd romance between a hardworking college student and her rather mysterious senior. Nam Joo-hyuk played the best friend of Go-eun’s character, while Lee Sung-kyung played the dramatic, obnoxious childhood friend of Hae-jin’s character, whom she’s madly in love with. Later that same year, Nam Joo-hyuk and Lee Sung-kyung were both cast for the lead roles in Weightlifting Fairy Kim Bok-joo, a coming-of-age romance drama about a female weightlifter who discovers love and self-acceptance. The following year, reports came out that the co-stars were dating, which they both admitted a little later on. However, news of their split-up came after a couple of months, citing conflicting schedules and personal matters as the cause.

Park Seo-joon and Hwang Jung-eum


This particular pair might be the oddest reunion of this list. In Kill Me, Heal Me (2015), Hwang Jung-eum played a resident doctor, alongside Ji Sung, who played a man who has dissociative identity disorder and has seven personalities. In the drama, Park Seo-joon played Jung-eum’s twin brother and a mystery novel writer who follows celebrities and chaebol heirs and exposes their scandals and secrets.

The main female character, however, is ashamed for she finds herself unattractive, so she asks another friend to pretend as her and meet him. However, things take a different turn when she discovers that the friend she’s hiding from is her new boss at a fashion magazine company. From siblings to lovers, both stars impressively showed their chemistry in both roles.

Song Joong-ki and Kim Ji-won

When he does find her, things start going wrong as he falls for her. Lee Dong-wook and Yoo In-na’s onscreen chemistry in the series was so intense, they were comparable to the lead couple’s. They were eventually given a project together as leads, still as lovers, in the tvN romance series Touch Your Heart (2019), which follows a celebrity who has to leave the limelight due to a scandal and ends up becoming a lawyer’s secretary.

Jin Goo and Kim Ji-won


Not only did Kim Ji-won reunite with Descendants of the Sun co-actor Song Joong-ki, she also reunited with her then love interest Jin Goo. In the 2016 drama, Kim Ji-won portrayed a military doctor who is also the daughter of the high general, and Jin Goo played a a sergeant major. Ji-won’s and Jin Goo’s characters started to have conflict in their relationship after Ji-won’s father threatens the sergeant major for dating his daughter. Although he strayed away, she never gave up on him, constantly following him in wherever country he was assigned to. In 2018, the two met again on the set of Mr. Sunshine, this time, with supporting roles as the lead female character’s parents. Mr. Sunshine centers on a boy born to slavery who was able to escape to the United States. Years after, he comes back to Korea as a captain in the Marine Corps and falls for an aristocrat’s daughter. He also uncovers a plot of foreign forces attempting to colonize his home country. It starred Lee Byung-hun and Kim Tae-ri and was spearheaded by Descendants of the Sun makers, director Lee Eung-bok and screenwriter Kim Eun-sook.

Kim Jung-hyun and Seo Ji-hye


Before they starred in Crash Landing on You and broke our hearts, Kim Jung-hyun and Seo Ji-hye previously worked together in the romance series Jealousy Incarnate back in 2016. It follows the competition of anchors in a broadcasting company and the relationship between a weather caster, played by Gong Hyo-jin, and a co-anchor, played by Jo Jung-suk.

Ji-hye played an heiress from a reputable family in North Korea and is engaged to Hyun Bin’s character. Due to unexpected circumstances, she falls for a professional con artist, played by Jung-hyun. Although their love story was brief and tragic, the stars met again months later in Seo Ji-hye’s new project Dinner Mate with Hallyu star Song Seung-heon. Kim Jung-hyun made a cameo appearance as Ji-hye’s onscreen ex-boyfriend. Sad to say, the two never seem to end up together.


It was Princess Lulu who first introduced her to Korean dramas but it was Yoon Ji-hoo from Boys Over Flowers who enticed her to stay in K-dramaland. She writes news and features for Kdramapal, which combines two of her most favorite things in the world—writing and K-dramas (look who's living the dream). The name Luna literally translates to "moon" and nothing special; she just likes writing at night.
