INFINITE's Sunggyu recently guested on KBS 2TV's 'Hello', where he showed off his close relationship with MC Shin Dong Yup.

Sunggyu answered a question about his worries and said, "I don't usually have worries, but I started to have one when I met Hyosung not too long ago. When I came in, I didn't know this, she told me that my socks weren't matching," drawing out laughter from the audience.

Mid-episode, the idol was asked about what he does during his free time, Sunggyu said, "I like to go drinking and get massages. I recently met Shin Dong Yup at a sauna at Yeoyido, Seoul. I didn't want to greet him because I thought that he would be embarrassed." 

MC Lee Young Ja then asked, Sunggyu, "Did you see everything?" to which Sunggyu replied shyly, "I saw everything. He was good," putting two thumbs up. Shin Dong Yup then expertly brushed off the situation and said, "Don't be intimidated. Have more confidence."

Meanwhile, Hyosung, Hong Jin Ho, and Kim Ye Rim also appeared on this week's 'Hello'.
