The relationship between the two began in 2016. Lee Sun-bin appeared on MBC's Radio Star and picked Lee Kwang-soo as his ideal type.
"I like a pleasant man, so I want to go to SBS Running Man'. I am a track and field athlete. I like to run. I'm confident that I'll do one good thing on the run," he said.
Lee Sun-bin's wish became a reality. He appeared on "Running Man" that year and played a Game with his ideal type Lee Kwang-soo.
Lee Kwang-soo asked Lee Sun-bin, "Is my ideal type really Lee Kwang-soo?" Lee Sun-bin replied, "Yes" without hesitation. The results were falsely judged as the alarm sounded.
Even at the end of the broadcast, Lee Kwang-soo said, "We decided to date from today. We will announce marriage next week."
In 2017, Lee found "Running Man" again, and Lee was delighted to cheer as soon as Lee appeared as a guest.
Kim Jong Kook and Haha said, "Lee Kwang-soo has not slept for two weeks." He said, "I really want to love."
Lee Sun-bin said, "Have you been keeping your mind about the light water?" Yoo Jae-Suk asked, "Yes."
Lee Sun-bin, who once again raised his hand to the lie detector, was asked, "I am still interested in Lee Kwang-soo." Lee Sun-bin replied, "Yes." The result of the lie detector was "sincere." The panel did not admit that it was "a lie detector."
The two men who have built up a relationship will develop into lovers between the line and juniors. On the 31st, Lee Kwang-soo's agency, King Kong Entertainment, said, "Lee Kwang-soo and Lee Sun-bin are in love."
"The two have been in good mood for five months through the Running Man'," Lee said. "The two are meeting with good feelings. Please look pretty," she said.
Lee Kwang-soo, a former fashion model, made his debut in 2008 with MBC TV sitcom "He Comes." He appeared in many works and became popular as a member of "Running Man".
Lee made his debut in the Chinese drama 'Seosung Wang Heeji' in 2014 and appeared in the drama 'Missing Nine', 'Criminal Mind' and the movie 'Goodbye Single'.
