TVXQ's Yunho responded to Kwanghee's questions about a girlfriend.

On the November 3rd episode of 'King of Invention', Yunho introduced a new invention for those who can't sleep well. He expressed to Kwanghee, "The theme is 'I can't sleep well.' There are things you have to try, so you can sleep. Or someone can let you lay your head on their arm." 

Kwanghee then responded and laughed, "I think Yunho hyung is dating someone these days. He said that someone could just let you lay on their arm. What does that mean?" The TVXQ member then said, "I can talk openly about this. I don't have a girlfriend."
