One of the last scenes in the drama required Kim Se Jung to do some cringy aegyo in front of her boyfriend. Regarding the viral scene, Kim Se Jung revealed, "That was actually the last filming, and I was extremely tired at the time because I wasn't able to sleep almost every day."

She continued, "I would've said 'I can't do it' if it was on any other day, but I was so tired that I said, 'Yes!' and carried on with the aegyo."
