South Korean actor Lee Kwang-soo and his girlfriend Lee Sun-bin have enjoyed a stable relationship since publicly confirming their romance at the end of 2018, now marking their eighth year together. Recently, Lee appeared on an online show hosted by Yoo Jae-suk, where he sported a beaming smile—only to have Yoo reveal a behind-the-scenes secret: he proudly claimed to have played matchmaker for the couple. “I’m the reason they got together!” Yoo joked, prompting Lee Kwang-soo to nod in agreement.
During the show, Yoo recalled his past interactions with Lee, describing himself as a “love coach” who actively guided him, ultimately leading to his romance with Lee Sun-bin. Co-host Ji Seok-jin teased, “Didn’t you ruin it?” to which Yoo replied, “Not at all—they’re still going strong. Saying I helped them get together isn’t an exaggeration.” He described witnessing the entire journey from the couple meeting on Running Man to becoming partners.
Lee Kwang-soo and Lee Sun-bin first crossed paths in 2016 while filming Running Man, with Lee Sun-bin appearing as a guest and Lee Kwang-soo as a regular host. At the time, Lee Sun-bin had already mentioned in interviews that Lee Kwang-soo was her ideal type. The show even arranged a “Lee Kwang-soo One-Day Date” segment, bringing them closer together. By December 31, 2018, media reports revealed their relationship, which they openly confirmed had already been ongoing for five months.
Their romance remains strong, with both supporting each other’s careers. On the show, Lee Kwang-soo even promoted Lee Sun-bin’s new film Noise Kill, sharing affectionate moments that delighted fans.
