Seo Se Hyun is actually the biological daughter of Yoon Jo Kyun (played by Park Yong Woo), a serial killer involved in a string of unsolved mutilation cases. Even more disturbing, Seo Se Hyun—originally named Yoon Se Eun—was forced to become an accomplice to her father’s murders as a child.

Here are 7 dark and heartbreaking facts about Seo Se Hyun’s childhood that serve as key turning points in Hunter with a Scalpel:

1. Seo Se Hyun’s Real Name Was Yoon Se Eun, Daughter of Yoon Jo Kyun

Before taking on her new identity, she was known as Yoon Se Eun, the biological daughter of Yoon Jo Kyun. Her mother tragically died as a result of domestic abuse, leaving Se Eun to be raised solely by her murderous father.

2. Raised in a Shipping Container and Made a ‘Murder Assistant’

From the age of 5 to 10, Se Eun lived in complete isolation inside a metal shipping container, where her father carried out his horrific crimes. In this twisted environment, Se Eun was forced to assist in the murders, even though she didn’t fully understand what was happening. She was a child caught in pure horror.

3. Completely Isolated From the Outside World

During those years, Se Eun had no access to school, no proper food, and no interaction with anyone else. To her, her father was the only person in the world. Despite the abuse, he was her only lifeline—creating a disturbing and unhealthy dependency.

4. She Meets Her Half-Sister, Go Eun Seo

Se Eun’s world began to change when she met Go Eun Seo (played by Shin Yeon Woo), her half-sister from Jo Kyun’s previous marriage. Eun Seo treated her with love and care, and became the first person to show her genuine affection. Eun Seo taught her how to read and write—sparking a light in Se Eun’s dark world.

5. Begins to Discover the Outside World Through Eun Seo

Through Eun Seo’s care, Se Eun started to become aware of life beyond the container. She began to hope for freedom and normalcy. However, this terrified Jo Kyun, who feared losing control over his daughter and being exposed.

6. A Failed Escape and Tragic Ending

Once Eun Seo realized the truth behind Jo Kyun’s murders, she tried to escape with Se Eun. But their plan was discovered. In a moment of rage, Jo Kyun pushed Eun Seo off a cliff, killing her. Se Eun, in a state of trauma, buried her sister at the foot of the mountain before collapsing. She was later found unconscious by hikers.

7. Adopted by Nun Seo Won Hee and Given a New Life

After being rescued, Se Eun was adopted by Seo Won Hee (played by Kang Myung Joo), a kind-hearted nun who took pity on the child’s broken mental state. Under her loving care, Se Eun transformed into Seo Se Hyun, a compassionate and emotionally resilient woman—the complete opposite of her psychopathic father.

Seo Se Hyun’s Tragic Past Shaped Her Strength

Seo Se Hyun’s storyline in Hunter with a Scalpel isn’t just a chilling crime tale, but also a story of survival, redemption, and emotional healing.
