Kim Jae Joong's mother Oh Seo Jin revealed the hardships she faced as the daughter of a surrogate mother.

In MBN "Human Theater" aired yesterday, JYJ Kim Jae Joong's mother Oh Seo Jin's life story was revealed.

In November of 1961, Oh Seo Jin was born into a wealthy family. But she was treated badly because she was a daughter. She had been born as the daughter of a surrogate mother to a family who desperately wanted a son.

In her generation, the treatment to a son and a daughter were distinctively different. Even though her family was rich, her older brother attended kindergarten but she could not. And when she was 10, she found out that she was born through a different lady who was paid to bear her parents' child, bringing her into shock.
