#Q ORIGINAL QUESTION

Did Joo-yun's father know she was pregnant in I Saw the Devil?

What a correct answer would look like:

Yes, Joo-yun's father (Squad Chief Jang) knew she was pregnant, but only after her death. He was unaware while she was alive, as she had planned to surprise her fiancé with the news. The pregnancy was revealed to her father and fiancé through the autopsy/investigation after her dismembered remains were recovered. This revelation served as a devastating 'double blow' to her father, compounding his grief over the loss of his daughter with the loss of his unborn grandchild.

What the LLM said (errors and omissions annotated)

Based on internal knowledge of the film I Saw the Devil:

Yes, Joo-yun’s father (Squad Chief Jang) did know she was pregnant, but only after her death.

Here are the specific details regarding how and when this is established:

  1. He did not know while she was alive: Joo-yun had only recently discovered she was pregnant. On the night she was murdered, she was on the phone with her fiancé, Soo-hyeon, and was planning to tell him the news. It is implied that her father was entirely unaware of the pregnancy at that time.
  2. Discovery via Autopsy: After Kyung-chul murders her and disposes of her body in pieces, the police eventually recover her remains (specifically her torso). The medical examiner performs an autopsy and informs Chief Jang and Soo-hyeon of the pregnancy.
  3. The Emotional Impact: There is a specific, somber scene where the autopsy results are discussed. The revelation that she was pregnant serves as a "double blow" to Chief Jang—he realizes he didn't just lose his daughter, but also his unborn grandchild. This discovery is a primary factor in the overwhelming grief and eventual resignation he feels as he watches Soo-hyeon descend into a cycle of brutal, extrajudicial revenge.
  4. Confirmation in Dialogue: Later in the film, during conversations between Chief Jang and Soo-hyeon regarding the hunt for the killer, the loss of the "baby" is treated as a known fact between them, fueling the intensity of their hatred for the killer, Jang Kyung-chul.
