About her character in 'Doctors', she said, "Honestly, Jin Seo Woo's character is the complete opposite of my true personality. I worried a lot about how I would portray Seo Woo's weakness without making it hateful, but thankfully, she was able to show a more mature, grown side of her in the end, so I was sincerely happy."
For her role in her new drama, Lee Sung Kyung revealed, "I already gained 4kg. I wanted to healthily gain weight by exercising, but I ended up increasing my weight by eating."
Lee Sung Kyung's new drama 'Weightlifting Fairy Kim Bok Joo' begins airing September 21.
