It's only weeks since Lee Sung Kyung and Nam Joo Hyuk proclaimed their relationship to the public. Fans are surely waiting for the actress to spill a little bit of secret about her dating life with Nam Joo Hyuk.

On a recent interview with GRAZIA Korea, Lee Sung Kyung finally spoke up how she developed a romance with Nam Joo Hyuk in the filming set of "Weightlifting Fairy Kim Bok Joo". According to Korea Portal, Lee Sung Kyung described her boyfriend as someone who helps her get into the character of Kim Bok Joo. Nam Joo Hyuk's charm apparently helped her to create the best circumstance while filming.

"Nam Joo Hyuk and I are very close long before we met in the drama. It was nice and comfortable while filming. He helped me to be at my best conditions," said Lee Sung Kyung when asked how it felt to work with Nam Joo Hyuk.

Lee Sung Kyung also admitted that portraying Kim Bok Joo was never an easy thing to do until Nam Joo Hyuk convinced her that she can pull off the character just well. Her antagonist character in "Cheese In The Trap" was the thing that made Lee Sung Kyung not sure about the outcome of "Weightlifting Fairy Kim Bok Joo".

Lee Sung Kyung and Nam Joo Hyuk announced their relationship to public on April 24, Soompi reported. The actors under YG Entertainment decided to go public after pictures of them on dates leaked on the internet. However, fans had been suspecting them as a real-life couple long before the pictures leaked.

Lee Sung Kyung reportedly will be portraying a wrestler for her upcoming project "Love Sling". If she accepts the role, she will be Yoo Hae Jin's co-star in the movie. As of now, Lee Sung Kyung hasn't confirmed if she's going to take the offer since she's very selective about the roles offered in for both big screens and televisions.
