On the October 10 installment of Mnet's 'EXO 90:2014,' EXO's D.O talked about the slapping scene he had to endure while filming his movie, 'Cart.'

While watching Lee Jung Jae's slapping scene on the show, D.O said, "I've been slapped before, and at the moment, I laugh if it hurts too much.  I wondered if he caused an NG because he was too taken aback from the pain.  I was slapped by Kim Hee Won [in the movie 'Cart'].  I bowed my head down because I was worried I'd cause an NG.  But to tell the truth, it is harder for the person doing the slapping. It was a really good experience."
