During a round of 'Yes or No' questions, the actor was asked, "I like Lee Kwang Soo more than girl groups." Song Joong Ki answered without a moment's hesitation, "No. I like girl groups more," bringing laughter with his honesty.
Song Joong Ki may prefer girl groups over Lee Kwang Soo, but since he can't really bring a girl group for his travels, Lee Kwang Soo will have to make do. Song Joong Ki said, "I absolutely must take Kwang Soo. Because I need someone to pay for me....just kidding. It's because he's a really close friend of mine so I have to go on a trip with him whenever I can."
