During the ad filming for the "Turkey Collection," members of DAY6, including Young K, were amazed as he devoured an impressive total of 11 Subway sandwiches. Subway Korea organized a contest where fans could guess the number of sandwiches Young K ate, with ten winners selected to receive prizes from the brand.

In a social media post, Subway Korea revealed the winners of the competition, praising Young K's voracious appetite. Fans were taken aback by Young K's capacity to consume such a large quantity of food in one sitting, with one fan even calculating that the total length of the subs was equivalent to 165 cm.

Korean netizens and fans expressed their astonishment at Young K's eating prowess, marveling at the fact he managed to finish 11 sandwiches. Some joked that he could have easily polished off one more sandwich, making it a total of 180 cm long. Despite his remarkable eating abilities, fans marveled at how Young K manages to maintain his slender figure, with some suggesting he could have pursued a career as a Mukbang YouTuber if not for his singing talent.
