"Respond 1997" Jung Eunji gave a very realistic childbearing performance.

On the finale of "Respond 1997," Sung Si Won (Jung Eunji) gives birth to her baby. This is March 2013, because she began labor earlier than predicted, husband Yoon Yoon Jae hurries upt to Seoul from Daejeon.

Yoon Yoon Jae runs into the room and panics saying, "You're almost there, almost there, huh?"

Then in the throes of labor, she explodes in anger, "What do you mean I'm almost there you asshole! This is all because of you, you ****!!" and cursed him out, pulling out his hair as well. He apologizes profusely. 

Just before this scene, the couple had attended their school reunion, where Do Hak Chan (Eun Ji Won) said "Don't be around for her giving birth. Knowing her personality, she'll throw a fit and swear to high heavens." To that Si Won says, "I'm not a mobster, I won't do that. Don't be scared, I won't do that to you." However, she had changed 180 degrees in actual labor.

Viewers responded positively to her realistic portrayal of labor and childbirth.
