In the first part of the King's King, which was broadcast last week, Lena Park, Sunmi, Kim Min-jong, Song Ga-in, Cho Kyuhyun, Zanabi Choi Jung-hoon and Uhm Jung-hwa were released. In the second part of the broadcast, Kim Dong-Hyun, who played the song of Shin Yong Jae, the king of the high-pitched end, Kim Hee-seok, who misunderstood Young Tak, Kim Ye-jin, who resembles Noh Sa-yeon from voice to appearance, and Kim Jong-han, who made the audience cry with the sensibility of Kim Hyun-sik. Prior to the confrontation, the active support of the Original Singers also attracted attention. Jessie Gifted her trademark ring earrings for the stage ahead. Jessie said, "This has been my confidence since I was a child," and Jo Ha-yul was thrilled, saying, "I'm going to put it by my bedside." Jessie responded, "Do it. The color rots anyway." Kim Dong-Hyun appeared with a cake celebrating the 14th anniversary of Shin Yong Jae's debut. Shin Yong Jae also told Kim Dong-Hyun, "When you call 'Reason for becoming a Singer', physical strength is important." Kim Dong-Hyun said, "I will take a three-point shot and take my brother's stamina." Young Tak also called Kim Hee-seok to the studio before the stage and was surprised to proceed with the Spatra special. Song Eun, who watched Young Tak's Spartan lecture, explained the reason for his extraordinary passion, saying, "Originally, Young Tak was a professor of practical music." On the other hand, Original Singer Kim Min-jong and Zanabi Choi Jung-hoon, who watched the perfect stage of The Capable Ones, attracted attention with the expression of tension as time passed. Since then, KIM Jong-jong has given a stage of 'White Nostalgia' with five talented people, and has also made the Christmas sensibility of the 90s white in the room.
