Early on August 26, a source tipped off the press about the actor potentially not appearing in the second half of the series. The news was later confirmed by a representative for MBC later that day.

"Kim Jung Hyun was forced to leave due to health problems," the representative revealed, adding that despite the actor's efforts to continue working until the end of production, he required both mental and physical rest. "We hope he gets well soon, and he is able to return to working in better condition."
