Choi Si Hwan wants to work with Hwang Jung Eum again. That's not surprising. The two have so much onscreen chemistry that they have given "She Was Pretty" viewers a serious case of Second Lead Syndrome.

The actor called in on the November 3 episode of the SBS show Kim Chang Ryul's Old School. Fellow Super Junior member Kangin was serving as a guest DJ.

Kangin asked him if there was an actress that he wanted to work with.

At first Choi Siwon seemed to be focused on his upcoming enlistment, which takes place in November, shortly after the final episode of "She Was Pretty."

"I can't afford to think about that now," he said. "I need to prepare for my enlistment."

But then he could not resist putting in a good word for his co-star.

"If the opportunity presents itself I want to work with Jung Eum again. Jung Eum and I have a great synergy. Entertaining scenes become even more entertaining and emotional scenes go even deeper. She′s an actress who doesn′t stand out but keeps a good balance."

Perhaps when he finishes his two-year mandatory military duty, they could appear in a drama as the leads. That's what happened to Hwang Jung Eum and Park Seo Joon. They played stepbrother and sister in "Kill Me Heal Me" and had such good chemistry that producers for "She Was Pretty" saw them in leading roles together.

"I really like working with Park Seo Joon," Hwang said at the press conference for "She Was Pretty." "When I was working with him in "Kill Me Heal Me, I got the sense that he is a fun and talented actor, I think he has stepped up his game now."

She and Park are openly affectionate and friendly on set.

Choi Si Won is not the first actor to want a second chance to act with Hwang Jung Eum. She starred in two dramas with Ji Sung, "Kill Me, Heal Me" and the melodrama "Secret Love." She has praised him for being a considerate co-star and a fine actor.

He described her as a "good friend" and a "meaningful and precious partner."

She must be fun and supportive to work with.

K-drama producers take note. Viewers would like to see a drama with Choi Si Won and Hwang Jung Eum in the lead when his tour of duty is done. Anyone else agree?
