Since D.O. filmed 'Cart' before 'It's Okay, That's Love', he commented on his acting debut; "I was nervous because they're veteran sunbaenims, but they all cheered me on so I learned a lot while filming... Yeom Jung Ah sunbaenim, especially, treated me comfortably like my real mother so I was able to loosen up."

'Cart' has already been invited to the 'Toronto International Film Festival' ('TIFF'), Busan International Film Festival ('BIFF'), and Hawaii International Film Festival ('HIFF'). It will premiere in Korea this November!
