Rumors surrounding Korean entertainment icons Lee Sung Kyung and Nam Joo Hyuk often surface online, frequently confusing fans who mix up past real-life dating history with false marriage reports. To clear up the confusion immediately: Lee Sung Kyung and Nam Joo Hyuk are not married, nor are they currently dating. They were a real-life couple for a few months in 2017 after co-starring in the hit television series Weightlifting Fairy Kim Bok Joo, but they broke up later that same year due to busy schedules.
Understanding why fans still obsess over this pairing requires looking back at their mutual rise from fashion models to global Hallyu stars, the reality of their brief romance, and why internet rumors continue to circulate.
From Runway Models to Leading Actors
Long before capturing international attention as actors, both stars built successful careers in the fashion industry under YG Entertainment. Standing out in South Korea's competitive modeling scene, they transitioned into acting around the same time.
Their professional paths first crossed on screen in the 2016 tvN drama Cheese in the Trap. While they weren't romantic partners in that series, the shared experience laid the groundwork for a close friendship. That friendship transformed into undeniable chemistry when MBC cast them as the leads in Weightlifting Fairy Kim Bok Joo later that year.
Portraying collegiate athletes Kim Bok Joo and Jung Joon Hyung, their playful banter and organic emotional depth resonated deeply with viewers. That on-screen dynamic didn't stop when the cameras turned off.
The 2017 Relationship and Breakup Timeline
In April 2017, South Korean media outlet Dispatch published photographs of the pair, prompting their agency, YG Entertainment, to confirm that the co-stars had transitioned from close friends to a romantic couple. According to statements released at the time, they officially began dating in January 2017 after growing closer during the final stretches of filming their drama.
For fans of Korean dramas, seeing an on-screen ship become a real-life couple felt like a fairy tale ending. However, the high-profile romance was short-lived. In August 2017, just four months after public confirmation, YG Entertainment announced that the couple had broken up.
Both actors cited conflicting schedules and demanding career paths as the reasons for the split. Since then, they have pursued independent professional trajectories, starring in separate film and television projects without any official reunion.
Why Fans Still Hope for a Reunion
Despite years passing since their breakup, internet forums, social media platforms like TikTok, and fan communities regularly revive theories that the two might be secretly together or planning to marry. This phenomenon stems from several distinct factors:
- The Power of Nostalgia: Weightlifting Fairy Kim Bok Joo remains a comfort watch for millions globally. The emotional attachment viewers have to characters Bok Joo and Joon Hyung often transfers directly to the actors.
- Retained Social Media Traces: Unlike many celebrity couples who scrub their social media profiles clean after a split, old photos from their working days and modeling collaborations remained visible online, fueling endless speculation from optimistic fans.
- Absence of High-Profile Public Exes: Neither actor has heavily publicized a major subsequent relationship that captured the public imagination in the same way, leaving room for wishful thinking.
