The singer disclosed that before he made his official comeback, he passed time productively by learning new hobbies such as yoga and cooking. He elaborated, "I took six classes and learned Korean, Western, and Japanese cuisine. I learned [one type of cuisine] per day and on the last day, learned a combination of different cuisines."�

Among the dishes he knows how to prepare, Lee Seung Gi chose ddeokbokki (spicy rice cakes) as his best dish. He boasted, "People around me tell me that [my ddeokbokki] is the most delicious." Yoo Hee Yeol saw this confession as a golden opportunity and seized it by asking the singer, "Who was the person most impressed by your ddeokbokki dish?", hoping for Lee Seung Gi to mention YoonA. The singer tentatively answered, "I don't know what you are all imagining but a lot of women enjoyed [my dish]," possibly implying that YoonA was one of the "many women."

Lee Seung Gi also put on a magnificent duet with his mentor Lee Sun Hee by performing an impressive rendition of Buzz's "Thorn" and an equally impressive solo stage with a performance of his song "Turning Back."�
