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) spend the night at the home of Master Lee Sunhee (이선희). The singer (and Lee Seung Gi's former mentor) continues to devote her life to her career and will go to extremes to preserve her voice which is her asset. Not only does she wear scarves to protect her voice from the cold elements, she talks in a barely audible tone when at home and chooses not talk at all in the morning prior to her vocals warm-ups, preferring to write on a notepad.
