On March 21, Kim Hee-won guested on JTBC's talk show 'Knowing Brothers'.
Kim Hee-won said, "In 'Cart', there was a scene where I had to slap D.O. in his face. As D.O. was really into his character, I slapped him hard in order to look more real."
He continued, "At that time though, there were a lot of his fans on the site, watching us."
He went on, "When I slapped him, they screamed and shouted, 'No!' So, we had to retake the scene a couple of times.
He said, "In the end though, I had to explain the situation to his fans and ask for their understanding."
