Broadcasted on February 10, the singer went to work along with MC Lee Kyung Kyu, actress/singer Chae Jung Ahn and construction expert Mr. Yang.  Their mission was to transform a mice-infested makeshift house, that used to be a warehouse, into a beautiful home.  On the living conditions, the teenage girl commented, "I'm afraid to go to the restroom."

Soon, the house was completely demolished as Kim Jong Kook put all his energy into creating a safe and sanitary environment for the developing teenager who is a huge fan of BTS.  He stated, "I don't feel like a stranger to Min Young's family.  I just want to present a comfortable home for them."

Afterward, seeing the brand new modern home brought a smile on everyone's faces.  The grandma was overwhelmed and shed tears, thanking everyone for the new beautiful home.
