[ENG SUB]Behind the scenes video of Jang Nara and Alec Su in My Mischievous Princess

Made a compilation of them during the behind the scene filming of My Mischievous/bratty princess. It's interesting to hear their real voice which you wouldn't be able to hear in the actual drama due to the dubbing. Jang Nara speaks Korean while Alec Su speaks in Chinese, how did they even communicate...
