Regarding their acting chemistry, IU said, "Byun Woo-seok and I briefly worked together about 10 years ago on another project, but this time we are properly partnering in this drama. It felt comfortable from the reading session. We shared many ideas on set and encouraged each other, building great chemistry." Byun Woo-seok also said, "Every time we filmed, IU and the staff showed great consideration and support, which really helped our chemistry."
