Hwang Jung Eum said she would like to get married before she stars in another drama with Ji Sung.

In a recent interview with Korean media outlet Joongang Daily, Hwang talked about her working partnership with Ji Sung. "Kill Me, Heal Me" was their second successful drama together as they were previously paired up in the surprise hit melodrama "Secrets."

She had nothing but praise for her co-star saying that she has a lot to learn from him as an actor. In "Kill Me, Heal Me" he played a corporate heir with seven different personalities. She played his psychiatrist and an important part of his cure.

Not only did Ji Sung have to switch personalities in the blink of an eye but Hwang Jung Eum's character also had to react to and treat each of them.

Hwang said that Ji Sung was very helpful on set and she praised his patience.

"One thing I really like about him is that he always patiently explains things I don't get," she said. "For me, I can't act when I don't understand. He always explains so patiently and kindly."

And she also praised his talent in delivering so many relatable personalities.

"It must have been really challenging, but seeing him act I could see he's in that level," she said. "If it were me, I wouldn't be able to do that, especially given that we slept about 30 minutes to an hour every day during filming."

Playing against the different personalities was a challenge because it was difficult to control the situation. When asked if she saw herself co-starring with the actor again, she said yes but with one condition.

"Definitely, but maybe in four years' time," she said. "He's married now. So maybe we can play a couple after I get married, too."

The 30-year-old actress, who debuted with the girl group Sugar, has no immediate marriage plans.

"I want to go with the flow and let things happen naturally. I want to get married at 33 or 34 with someone I'm dating then. I think it could be Yong Jun."

Hwang has dated Kim Yong Jun of the ballad trio SG Wannabe for almost a decade. The couple met in 2005 when the actress starred in the SG Wannabe music video "My Heart's Treasure Box." They went public with their relationship in January of 2008.

Ji Sung is married to actress Lee Bo Young and the couple is expecting their first child this year.
