In “Master in the House” (집사부일체), butlers singer / actor Lee Seung Gi (이승기), BTOB’s Yook Sungjae (육성재), actor Lee Sang Yoon (이상윤) and comedian Yang Sehyung (양세형) visits the secret sanctuary of ballad singer who is considered an "Icon of Korean pop" Lee Moonsae (이문세) to experience the singer's double life as a mountain biker in Bongpyeong, Gangwon-do. Master Lee Moonsae took up mountain biking to overcome his timid and shy nature and the secluded resort villa referred to as the "Stable" that he religiously retreats to helps him to relax in order to be able to perform at his best as a singer, since "if you do not relax, you can not always be the best. If tension persists, energy is discharged, then 60% is mistaken for the best, and the audience feels it too". Master Lee Moonsae explains to the butlers that in contrast to the hectic digital life in Seoul, Bongpyeong represents the analog life as he prefers to interact with the villagers at the markets rather than via mobile apps, and it is where he can truly slow down and relax.
