Acting together for the musical 'Bonnie and Clyde', the two idols portrayed a romantic love interest, but Hyungsik said that the romance didn't manifest itself in real life. "Honestly, when I was doing it, I didn't feel any emotion at all," he said during an interview on 'Section TV'.

"Instead of thinking about the kiss, I'm focused on thinking about what emotions I should portray, so I don't have the time to think about anything else," he said. "I just did my best."

Despite his focus, however, Hyungsik revealed he still made mistakes! "Once, I was singing and I forgot my lyrics onstage. It's a really huge mistake," he said. "I got really punished for that backstage."
