April 28, an episode of the SBS weekend drama "The Secret of Birth" featured Jung Yi Hyun (Sung Yoo Ri) falling into a state of shock when she becomes confused about her own identity.

In this episode, Jung Yi Hyun goes to her friend Lee Sun Young's (Lee Jin) house but she is not able to meet her. Instead, Jung Yi Hyun tries to speak to Lee Sun Young's older sister Lee Hye Young but she just says that she is extremely busy and leaves after handing her some money.

Later in a hotel room, Jung Yi Hyun begins to wonder about why Lee Hye Young gave her money. She then tries to think of an event when something bad had happened to her. Regardless of her efforts, she is unable to remember anything.

Further into the drama, Jung Yi Hyun tries to visit her father but she cannot meet him as well. Jung Yi Hyun sits down in the middle of the campus and tries to remember all the things in the year 1997.

How is it possible that she cannot remember anything from 1997 to 2007? What happened during those 10 years? Did she get into a car accident? She then looks at her chest and yells out, "I had a baby? Am I married? With who?!?"
