Reality TV stars Lee Gwanhee and Yoo Sieun are dating in a relationship that began in December 2025, according to an exclusive report from Sports Chosun. Despite leaving the popular Netflix reality program Single’s Inferno 3 with different partners—with Lee choosing Choi Hyeseon and Yoo picking Choi Minwoo—the two stayed in touch, transitioned from friends to lovers, and recently confirmed their romance publicly through a joint Instagram post.
Single’s Inferno 3 Stars Turn Friendship Into Romance
Fans of the hit Netflix dating series first watched Lee Gwanhee and Yoo Sieun navigate the complex social dynamics of the show during its third season. While the pair did not couple up on screen, their connection persisted long after filming wrapped. According to Sports Chosun, they maintained regular contact, eventually meeting up at various events, including a public appearance by Yoo Sieun at the 2024 KBL all-star game where Lee Gwanhee played.
Over time, that post-show camaraderie grew into a romantic relationship. Media outlets and fans captured signs of their developing bond, including a spotted outing at an aquarium. Rather than keeping the romance private, the couple chose to address their supporters directly.
