First baseman for the Lotte Giants of the KBO League and former Seattle Mariners first baseman, Master Lee Daeho (이대호) shares his experiences with the butlers - singer / actor Lee Seung Gi (이승기), BTOB’s Yook Sungjae (육성재), actor Lee Sang Yoon (이상윤) and comedian Yang Sehyung (양세형) in “Master in the House” (집사부일체). Over two days, the butlers get a first-hand glimpse into what life as a professional baseball player entails under the strict guidance of Master Lee Daeho, who is nicknamed “King” for his incredible drive and determination. The butlers are first set on a gruelling hike up to Baegunam, a small temple around the Tongdo temple in the breathtakingly scenic mountains in Yangsan, Gyeongsangnam-do. Once they have reached Baegunam, Master Lee Daeho sets the butlers on a taxing fitness regime with just an apple for lunch, which are typical of his intensive winter training sessions. His home exudes warmth and cosiness as he displays his other side as a family man and doting father of two young children. The special room inside his home is a museum displaying his incredible collection of personal memorabilia including signed gloves, balls and trophies.
