To TV Report, the producer said, "Key is a friend who works extremely hard. He prepares thoroughly beforehand and is an actor who studies his character in depth. He also receives a lot of love from the staff."
The producer then revealed the reason he chose Key, who had no acting experience in the past, for the drama. Choi stated, "During the audition, he didn't have any drama experience, but that actually made him fresher. Also, his acting and sound were good, so that got me to cast him."
