Uploaded on the Empress Ki official website back in December 2013, Ji Chang Wook talks about his character Ta Hwan, filming in the cold, and working with his co-stars in this video. Note that he gave this interview when they were still filming the first half of the series, so whatever he said was only based on what he knew back then.

JCW never ceases to amaze me! He has a very mature and sincere attitude about his character acting for a young actor. Because of his attitude and mind set about his profession, he’ll go far~ ❤
thanks a lot for the english sub.thank u Gabby and Cherkell
I love how he described his rival character who basically can do everything, BUT TH’s charm is the innocent, childlike, “well-rounded” character.. i understand well-rounded here as a character with transformation.. >,<
Many thx! He is soooooo cute, handsome and smart boy! Saranghae chang wook ah.
thank u ❤
I also watch this video long time ago and then got blocked. Thanks for the subs!
