On the 3rd episode of KBS 2TV drama 'Secret' (Script Yu Bora, Choi Ho Chul, Production Lee Eung Bok, Baek Sang Hoon), which was broadcasted on October 2, 2013, Kang Yu Jung (Hwang Jung Eum) gave birth to a child in prison.
Kang Yu Jung voluntarily undertook her lover An Do Hoon (Bae Su Bin)'s crime and went to the prison, leaving her father (Kang Nam Gil) in dementia alone. On the first day in the prison, she was beaten nearly to death, passed out, and was moved to the hospital.
It had later turned out that Kang Yu Jung was pregnant. An Do Hoon, who at the time of the news of Kang Yu Jung's pregnancy was sending Kang Yu Jung's dad, who had been suffering from terrible pain, into the surgery room, shed tears at the news.
Kang Yu Jung gave a birth of An Do Hun's child in prison while living her five year sentence. Kang Yu Jung cried tears of joy and sadness while holding the baby.
