Season 5 of Single’s Inferno is reaching its climax, and with each episode, the drama intensifies. The latest episodes premiered on January 20, 2026, and new episodes 8, 9, and 10 will be available on February 3, 2026. As the series unfolds, viewers have been keen to learn more about the contestants, including Lee Sung Hun, who is currently embroiled in cheating allegations. Recent reports have also drawn attention to his potentially high-profile family background.
Speculation regarding Lee Sung Hun’s lineage has emerged, particularly surrounding his alleged connection to former South Korean President Lee Myung Bak. A report by Koreaboo suggests that the 25-year-old contestant might be the maternal grandson of the former president. Online discussions within Korean communities indicate that his mother is claimed to be Lee Myung Bak’s eldest daughter, who graduated from Juilliard, while his father is said to hold a significant position at Samsung Electronics.
Fans of the show have pointed out striking similarities between Lee Sung Hun and the former president, noting their shared facial features and voice. These perceived resemblances bolster the claims about his influential family background. Additionally, Lee’s academic accomplishments—a degree in computer science from UC Berkeley and a career as a quant trader in New York City—are often cited as indicators of a privileged upbringing. Nevertheless, none of these familial connections have been confirmed by Lee or the show’s producers.
Before the attention on his family ties, Lee Sung Hun found himself in the midst of controversy due to allegations of infidelity. These claims surged on social media platforms such as Reddit, where users have circulated screenshots and anecdotes from his past relationships. He has faced accusations of cheating on his ex-girlfriend, popular social media influencer Hena Yang. The situation escalated when fans noted that Yang had removed all traces of Sung Hun from her social media following the show’s airing. Furthermore, Sung Hun changed his Instagram handle shortly after the premiere.
Adding to the drama, Lee Sung Hun’s social media account was reportedly deleted just a day after Single’s Inferno Season 5 launched. He has publicly denied the cheating allegations via Instagram, labeling them as unfounded. Despite his denial, online chatter continued, particularly after another influencer, FlawlessKevin, claimed to have met Sung Hun during his purported relationship with Yang. This meeting prompted further inquiries into the nature of his friendships.
Lee Sung Hun stated that his encounter with FlawlessKevin was merely a friendly outing, denying any romantic involvement. While some fans are convinced by his account and maintain that there is insufficient evidence to support the allegations, others suggest that the duo’s connection may have originated on a dating app. Some users allege that their meeting was a date and insinuate that they may have engaged in physical intimacy.
With ongoing speculation about both his family background and personal relationships, Lee Sung Hun remains a focal point of discussion among fans. The continuing narrative surrounding him raises questions about the balance between public persona and private life on reality television. How do you perceive Lee Sung Hun’s high-profile connections and the cheating accusations against him?
