On the August 11th installment of 'Knowing Brothers', Kang Ho Dong put the two friends on blast by saying, "When Son Dam Bi looks at Heechul, there's jealousy there." Lee Sang Min then added, "About 4-5 years ago, Heechul and I were eating BBQ in the early morning, and Son Dam Bi came over in 15 minutes after Heechul called her."
Kang Ho Dong also revealed, "Heechul calls Son Dam Bi 'my woman,' and she calls him 'my man.'" However, Heechul and Son Dam Bi denied everything, saying, "That was when we were young. We're just friends now. It's been 14 years."
She continued, "I've never thought of him as the opposite sex."
