On the March 22 airing of MBC's 'I Live Alone', Yunho and Changmin joined as the guests and revealed their single life. 

The 'I Live Alone' members asked Changmin if the two members visit each other's home often. He answered, "We lived separately for about 6 years now but we have never visited each other's home." 

Surprised at the answer, the 'I Live Alone' members asked, "Did you guys fight?" Changmin replied, "It's not that we had a fight but it's just because we lived together in a dorm for 15 years. We also lived together in Japan."
