Actor Kim Jung-eun's first foray back onto the entertainment scene in three years was in recently ended drama series "My Dangerous Wife.”

She took on the role of Jae-gyeong, a wife that initially comes across as a dangerous character with devious plans to take revenge against her cheating husband. The drama, which depicts what’s important to make a marriage work, ends on a positive note with the couple reconnected. Jae-gyeong's husband was played by actor Choi Won-young.

The actor, who lives in Hong Kong with her husband, came to Korea in March to start filming from mid-May, and lived as Jae-gyeong for seven months.

“There is always this kind of loneliness and emptiness an actor feels after each work is done, but I’m acting my best as if I’m not one of them,” said Kim, during an interview with Ilgan Sports, an affiliate of the Korea JoongAng Daily.

Below are edited excerpts from an interview in which she shared how she felt about the drama, and how it has been working in the entertainment scene over the past 25 years.
