The model-turned-actress said, "In my previous work ['Cheese in the Trap,'] because Baek In Ha has such a strong personality, when I'm standing still, viewers commented, 'It looks like Baek In Ha is standing still,' and, 'Baek In Ha is pretending to behave herself,' when I'm behaving myself. In a way, I'm also thankful that they see me as In Ha," addressing the viewers' opinion that her portrayal of Baek In Ha wasn't convincing enough.
Lee Sung Kyung continued, "[Baek In Ha] was a character with a long history but I lacked the time to really make her multi-dimensional and I didn't get to show those sides to her in the beginning of [Cheese in the Trap']. I had to show an impactful acting that would leave a strong impression and I worried that the character would not be explained well in the beginning. It was a good experience for me because I got to feel responsible [for my character] knowing that she'll appear a lot in the latter parts of the drama, and I think it was a thankful moment for me because I learned of my shortcomings and tried to improve them."
The actress then determined, "This time Jin Seo Woo (Lee Sung Kyung's character in 'Doctors') can't show any hints of In Ha. I wanted this character to seem different from In Ha because she is a different character. I hope [viewers] will understand [Jin Seo Woo] as a different character. She's not a weak character but she acts hurtful because she was hurt. She acts like that because she doesn't know [any better]."
Sounds like Lee Sung Kyung really wants to move on from her Baek In Ha character; we'll have to see if she succeeds when 'Doctors' starts airing!
