No matter how hard he tries, actor Joo Won continues to have a problem with kissing scenes. He may just need more practice.

On a recent episode of the show "Witch Hunt," Joo Won and his co-star Kim Ah Joong talked about their kissing scenes in the film "Catch Me."

He said that he put a lot of effort into the films' kissing scenes, but she seemed to think that he still lacked some confidence.

"Joo Won hasn't had a lot of kissing scenes," said Kim Ah Joong. "He's like a baby, But his character in the movie is like that so I made suggestions as to how he should approach me and told him how I would react."

That seemed to help them achieve the desired effect.

Kim Ah Joong is not the first actress who Joo Won has asked for or received kissing advice from. When he was filming "Level 7 Civil Servant" with co-star Choi Kang Hee, he asked her how they should do the kissing scenes.

"I waited for the first kissing scene and shot it with anticipation but there were so many, I became tired of them," he said. "I wondered if I should move with our lips touching or not. "

Choi Kang Hee suggested that he improvise, which he did. When he watched the final episode together with the drama's cast, he could not watch the kissing scenes out of embarrassment. But then he admitted that he was attracted to Choi Kang Hee and she told him that she never dated actors.

But "Level 7 Civil Servant" was not even his first embarrassing kissing incident. When he filmed "King of Baking, Kim Takgu," he confessed that those kissing scenes made him nervous too.

In his defense, kissing on dramas can be complicated by the fact that the actors don't really know each other, might actually be attracted to each other, lack experience, and because they often have to be filmed over and over again.

"You have to consider the camera angles," said Joo Won. "It must give viewers the right type of feeling."

On a KBS show "Win Win," Joo Won once confessed that he watched videos to learn how to perform kissing scenes.

"I watched a lot of different kiss scenes," he said. "And it helps that I always fall a little bit in love with the girl I kiss."

Practice makes perfect, Joo Won. Keep trying. It will get easier.
