The castmates / butlers of “Master in the House” (집사부일체) singer / actor Lee Seung Gi (이승기), BTOB’s Yook Sungjae (육성재), actor Lee Sang Yoon (이상윤) and comedian Yang Sehyung (양세형) spend a night with Master Jeon Ingwon (전인권) in order to learn from the legendary rock singer-songwriter and former lead singer of the band Deulgukhwa (들국화), who were known as the "Beatles of Korea". The butlers are in for a surprise as they discover that Master Jeon Ingwon lives a rather ordinary life in the same small house that he was born in the mountains. The humble house is situated in Samcheong-dong, Seoul which means three clean things – clean air, clean mountains and clean man. Master Jeon Ingwon explains that the house is a part of him and the place where he wrote most of his lyrics after his wife passed away. He has no intention of leaving as everything in the house has a meaning to him, such as the weeds growing in the garden, which gives him inspirations for his songs. The eccentric Rockstar lives a very un-Rockstar lifestyle, having quit drinking 7 years ago as well as going to bed at 9pm and waking up at 4am, whilst subsisting on a diet of mainly rice crusts and honey powder in order to avoid stomach aches before concerts. The house contains an eclectic mix of items he has accumulated over the years including a beautiful French rococo style bed.
