On August 26, 2018, it was announced that lead actor Kim Jung-hyun dropped out of the cast due to health concerns. His agency revealed that there would be no replacement for him and the production crew was working on revising the script for his character to naturally fall out of the story.[11][12] He officially finished filming on September 3.[13]
In July 2018, Kim Jung-Hyun was involved in a controversy over his "emotionless" behavior during a press conference.[14][unreliable source?] His agency, O& Entertainment, defended him by stating that "Because [Kim Jung Hyun] is spending a lot of time thinking about his character, immersing himself into the life of someone terminally ill every day, he had difficulty maintaining his [physical and mental] condition, and unintentionally made a mistake."[15][better source needed] In 2021 Kim released an apology letter regarding his behavior during that period, after a local tabloid claimed that he allegedly requested to remove several scenes that included physical contact with his then co-star.[16]
