Lee Kuk Ju invited the Gong Myung-Jung Hye Sung couple over for the Lunar New Year holiday, and neither her onscreen husband Sleepy or Jung Hye Sung were fond of Lee Kuk Ju and Gong Myung's friendship. The young idol-actor called Sleepy to see where their apartment was, but Sleepy decided not to answer.
Gong Myung then called Lee Kuk Ju, asking sweetly, "Nuna, which building and number are you?" Sleepy responded, "Why are you giving aegyo to another man's wife?" Lee Kuk Ju quickly explained, "We're close friends."
Gong Myung's onscreen wife Jung Hye Sung was also displeased by the way he acted towards the comedian, expressing, "I want to go home now," when she saw him hug Lee Kuk Ju.
