SEE ALSO: Which 'Roommate' Are You?

On the upcoming episode, we'll get to learn a little bit about Jo Se Ho's background as his parents tell the roommates some of their stories about the past. According to the preview articles released by the show, we'll find out that comedian's father was a former employee at IBM's South Korea branch, and the explanation behind the rumor of their family being a '3 billion KRW (~3 million USD) chaebol'. Judging by the video preview released, it seems some of the stories behind the family may be a sad one as everyone got teary. 

The roommates also prepared a coming-of-age party for the maknae of the bunch, fighter Song Ga Yeon, who previously revealed on the past episode that her father had passed away when she was younger and did not see her mother and sibling often. The touching gesture by the roommates brought the fighter to tears, showing that despite her tough exterior, she is still a young girl at heart.
