The "oppa Jaejoong" mentioned here is none other than singer Kim Jaejoong. Kim Jaejoong's appearance filled the recording site with great cheers.

Kim Jaejoong has experience not only as a singer but also as an actor in various works. On this day's "Gag Concert," he showcases his acting skills. He expresses the bittersweetness of first love with Jo Sooyeon and forms a rivalry with Shin Yoonseung, completing "Defconn Some How About It" like a weekend drama. Attention is focused on whether Shin Yoonseung can win the heart of "some girl" Jo Sooyeon in the competition with Kim Jaejoong, and whom Jo Sooyeon will choose between the two.

Additionally, in the "I Live Alone" segment, Oh Jungyul and Yoon Jaewoong, who are enjoying a Christmas party, encounter Grim Reapers Kim Yeowoon and Uh Youngjin. In this episode, the Grim Reapers bring something other than the ledger with the names of the deceased, causing laughter. In a situation where only one of the two can go to the afterlife, the Grim Reapers begin to recall the characteristics of the deceased based on memory. Uh Youngjin remembers the trait, "The living person said they liked luxury brand clothes." Upon hearing this, Oh Jungyul and Yoon Jaewoong hurriedly seek ways to transform their ordinary clothes into luxury brands. Curiosity grows about how they managed to create luxury brands on the spot.
