South Korean television series W - Two World came to an end on 14 September. In the drama, Lee Jong Suk and Han Hyo Joo played the lead roles and portrayed Kang Chul and Oh Yeon Joo, respectively.

Following the finale, the show's writer Song Jae Jung held a press conference on 20 September, and expressed her apologies to the 29-year-old South Korean actress for giving her the tough part. Jung said: "I gave her the hardest emotions to express."

"There are two intertwined stories in this drama. One is a romance where [Oh Yeon Joo] goes into a comic book, and one is [Kang Cheol's] conflict with his creator. Being involved in both worlds, Oh Yeon Joo was the one thrown into the most confusion," she added. "The character felt really sacrificial, so I was really sorry to Han Hyo Joo. I apologized to her so much at the final party. I'm wondering how I can ever pay her back."

Jung continued: "Oh Sung Moo (Kim Ui Sung) had a sad ending, and Kang Cheol (Lee Jong Suk) had a happy ending, but Oh Yeon Joo ending was not happy. They're a couple, but he was happy and she was not, and I'm sure that was hard for her. I believe that was my mistake. Forcing two [worlds] together, it just happened. Thank you [to Han Hyo Joo] for all your hard work, and I'll most definitely repay my debts to you."
