On December 15, the staff of the new tvN drama attended the press conference at Imperial Palace Seoul.
The male lead actor Lee Seung Gi brought laughter as he made an unusual promise for the drama's viewer ratings. He stated, "If the first episode surpasses 10% viewer ratings then I'll re-enlist in the military." He continued, "If we pass 10% then all of us will receive special permission from the Republic of Korea Army Special Warfare Command and experience training."
To this, netizens commented, "He's saying that because he knows it won't reach 10%", "Well, we know it's impossible to hit 10% on the first episode lol", "Lol you never know."
