On JTBC's 'Witch Hunt' on August 14, Sunggyu talked about a variety of things, one of which was the age he wanted to marry.

He said, "I will marry after I turn 40," grabbing attention. �Sung Si Kyung said, "There are 13 years left before you turn 40, so are you trying to enjoy it more during that time?" Sunggyu didn't take the bait, simply saying, "I don't yet want to marry quickly."

Lee Sung Min brought up his theory:�"His fans' love is so big that he has yet to meet a woman whose love is as big. �I had also compared my fans' and my girlfriend's love once in a while."

Sunggyu, however, replied, "That's not it," making everyone laugh. �He also revealed in this episode how he approached women. �When Sung Si Kyung asked, "If you like her, are you the type to ask for her number right away?" �

He replied, "You can ask if you like her." �Sung Si Kyung continued, "I feel like you'd just say, 'I like you.'" �Sunggyu confirmed this and Shin Dong Yup seemed pleased as he said, "That's what you should do."
