1. Song Joong Ki and Song Hye Kyo
The love story between Song Joong Ki and Song Hye Kyo (known as the SongSong couple), elevated fan feels to a whole new level. Way before the couple began filming mega K-drama hit Descendants of the Sun (DOTS) in 2015, Joong Ki was already dropping hints of being a fan of Hye Kyo's talent and beauty. He met her on the set of That Winter, the Wind Blows in 2012 when he made a surprise visit to see his close friend Jo In Sung, who starred alongside her. In one of her magazine interviews, Hye Kyo recalled their first meeting and talked about how Joong Ki greeted her as his sunbae (a Korean term for people with more experience). She also mentioned occasionally bumping into him by coincidence at cafés right after.
Joong Ki and Hye Kyo's OTL onscreen chemistry propelled the global popularity of DOTS and fueled well-wishes from supporters who kept their fingers crossed for the possibility of a real-life pairing. Shippers got their wish when news of the couple's relationship and engagement broke in July 2017. The revelation was proof that K-drama dreams can come true. Joong Ki and Hye Kyo tied the knot on October 31, 2017. Their wedding was a lavish, star-studded event that earned worldwide attention.
Just when the world was waiting for news of a SongSong baby, fan hearts broke when Joong Ki filed for divorce in June 2017. Hye Kyo's agency responded to news of the divorce right after by citing differences in personality as the main reason. By July 22, the Seoul Family Court approved the couple's divorce. On that same day, fans were shocked to discover that Hye Kyo deleted her photos with Song Joong Ki (including their wedding photo!) from her official IG account. Though fans can only speculate on what went wrong, it is undeniable that both were in love. It's sad to see how such love was not strong enough to be worth fighting for.
2. Ahn Jae Hyun and Ku Hye Sun
Ku Hye Sun of Boys Over Flowers fame met Ahn Jae Hyun (Cinderella with Four Knights) in 2015 while filming the K-drama Blood. The medical-fantasy drama, which marked Jae Hyun's first lead role, won viewers over with the couple's onscreen chemistry (the two stars played doctors drawn to each other by fate).
The couple got married in 2016, after a year of dating. Instead of spending on a grand wedding, Hye Sun and Jae Hyun shocked the world with their philanthropy by donating a significant amount to the pediatric ward of Severance Hospital in Seoul.
In an interview with Star Today, Hye Sun revealed how she avoided Jae Hyun at first and tried really hard to block her feelings for him. She talked about how her efforts failed and how he eventually won her over with his innocence and non-jaded personality.
The happily married couple are keeping busy with new projects. Hye Sun recently released a novel about love and relationships entitled, Tears Are Heart-Shaped. Jae Hyun, on the other hand, is gearing up for his new drama, People With Flaws.
Updated 18 August 2019: Another breakup is rocking the K-drama scene. HB entertainment, the agency of Hye Sun and Jae Hyun, released a statement announcing that the couple agreed to get a divorce. Unfortunately, the split was not amicable, and there was a lot of drama from either side.
3. Ji Sung and Lee Bo Young
Though the characters that Ji Sung (Kill Me, Heal Me) and Lee Bo Young (I Hear Your Voice) played in the 2004 drama Save the Last Dance for Me didn't end up together, the couple started dating a few years after the drama aired and went public with their relationship in 2007.
Ji Sung and Bo Young cemented a six-year relationship with marriage in 2013. The couple was blessed with a daughter, Ji Yoo, on June 12, 2015, and a son, Bo Ah, on February 4, 2019.
Ji Sung fans can catch him in new medical drama Doctor John, where he plays a genius but arrogant doctor of anaesthesiology.
4. Lee Min Ho and Park Min Young
Fans were not surprised when Lee Min Ho and Park Min Young admitted that they were in a relationship after the action K-drama City Hunter aired in 2011. Press statements from their agencies both echoed how both actors developed feelings for each other during the drama.
The couple dated for about five months before calling it quits. Their agencies announced that busy schedules and the pressure brought about by paparazzi following them wherever they go were the main reasons for the split.
Since their breakup, Min Ho has been linked to actresses Park Shin Hye (whom he starred with in The Heirs) and Bae Suzy (While You Were Sleeping). Though he denied reports of dating Shin Hye, Min Ho went public with his relationship with Suzy and dated her for approximately three years. Though she's been keeping herself busy by starring in dramas one after the other, Min Young has been strongly linked to her What's Wrong With Secretary Kim? leading man Park Seo Joon. Though both have denied their relationship, which was speculated to have started before the drama, their onscreen and behind-the-scenes chemistry have made some fans believe that their relationship goes beyond a purely platonic one.
5. Ki Tae Young and Eugene
Actor Ki Tae Young and former S.E.S idol-turned actress Eugene began dating after working together in manga-based drama Creating Destiny. The couple took things further and created their own destiny by tying the knot in 2011.
Eugene gave birth to their first daughter, Ro Hee in April 2015. The family of three was a viewer-favorite during their two-year stint in the family variety show The Return of Superman. Eugene and Tae Young welcomed their second child, Ro Run, in August 2018 and are still happily married.
6. Nam Joo Hyuk and Lee Sung Kyung
Models turned actors Nam Joo Hyuk and Lee Sung Kyung have been good friends since their modeling days. The YG Entertainment (YGE) actors were first cast as supporting actors in the 2016 drama Cheese in the Trap. On that same year, Joo Hyuk and Sung Kyung bagged their first lead roles and starred as a couple in breakthrough university drama Weightlifting Fairy Kim Bok Joo. The pair continued dating even after the show ended. Fan sightings of the lovely couple even include a concert date at Coldplay's 2017 show in Korea! Even if Joo Hyuk and Sung Kyung tried to keep their relationship low-key (by wearing face masks, sporting baggy clothes, and meeting in secret), paparazzi photos eventually surfaced forcing YGE to confirm their relationship.
A lot of fans cheered for Korea's best #swag couple and were super sad to hear about their breakup. Joo Hyuk and Sung Kyung sustained a very short relationship, which lasted for four months.
