Is Na Dae-il from Doctor X a psychopath? Meaning of the initial DN, comparison with the original work

A shocking twist in Episode 4 of the drama *Doctor X*! Is the true identity of the kind surgery professor Na Dae-il (Jang Seung-jo) a psychopath? We will neatly summarize everything at a glance, from the chilling meaning of the initials 'DN' engraved on a patient's organs to the differences from the original Japanese drama characters.

1. Doctor X Na Dae-il's True Identity, Turns Out to Be a Psychopath?

He'd been buying Gye Su-jeong her favorite bread and drinks, and showing his affection by saying things like, "You looked like a god, or a monster?" while watching surgery videos, so I just thought he was a heartwarming rival. But it turns out it was all just acting for the broadcast...

In Episode 4, a patient named Kwon Chung-hyun, an employee of a pharmaceutical company, is rushed into the emergency room. The two are senior and junior officers from the military; in the past, when Kwon Chung-hyun suffered severe internal bleeding due to military hazing, Na Dae-il performed surgery and saved his life. That is why he intends to ask Na Dae-il to perform the surgery again, trusting only him in this case.

The problem is that even after seeing all the CT scans, Na Dae-il strangely postpones the surgery for a week and makes excuses. Eventually, unable to bear it any longer, Gye Su-jeong performed emergency open surgery on Friday night, and the real reason was revealed.

Na Dae-il was a psychopath who deliberately delayed and interfered with the surgery not out of concern for the patient, but because he was afraid his bizarre past deeds would be exposed!

2. The chilling meaning of the initials 'DN' engraved on a patient's organs

While operating on the adhesions in Kwon Chung-hyun's abdomen, Gye Su-jeong witnesses a sight that makes her doubt her eyes. The letters 'ND' were clearly engraved on the surface of the patient's organs!

Meaning of DN: It stands for the initials of Na Dae-il's name, 'N'a 'D'ae-il.

Creepy point: 15 years ago, when he was a military doctor, he committed the bizarre act of carving his own name into the internal organs of patients he operated on, as if they were his property.

this I deliberately avoided and postponed Kwon Chung-hyun's surgery because I was afraid that the evidence called 'DN' would be revealed to the world through the open surgery, but by the time I finally rushed to the operating room, Gye Su-jeong had already confirmed those initials. Now that the true psychopathic nature hidden behind the kind face has been fully revealed, I'm really looking forward to seeing how the two of them confront each other!

3. Comparison of Characters in the Japanese Original *Doctor X* and the Korean Version

Those who have watched the original Japanese drama "You must have thought, 'Huh? Was there a psychopath character like this in the original work too?'" To start with the conclusion, a significant amount of original spicy flavor settings unique to the Korean version have been added!

Original Corresponding Character: This is Professor Hijikata Ikuya from Season 1. In the original work as well, he appears as a star surgery professor brought in by the hospital director to keep Daimon Michiko in check and lower her salary. He appears as a fellow doctor who knows Michiko's past, and they subtly engage in a battle of wits.

Differences in the Korean version: While the original story involved Michiko cleaning up a mistake made during surgery, the Korean version introduced an original setting where he is a "former long-serving military doctor." On top of that, the shocking thriller element of a "psychopath who carves his own name into a patient's organs" was added to significantly heighten the tension of the plot.

Furthermore, Na Dae-il is presumed to be a character deeply intertwined with Gye Su-jeong's trauma, the 'scene of an overseas disaster one year ago,' so it seems he will become the key to unlocking the secrets of Doctor X's past.

Q&A at a Glance

Q1. Is actor Na Dae-il's role a regular appearance or a special appearance?
A1. Although the role of Na Dae-il, played by actor Jang Seung-jo, is known to be a one-time/short-term special appearance, he is a character directly connected to Gye Su-jeong's past narrative, so his role is being portrayed with tremendous weight and impact!

Q2. What exactly does the initial discovered by Gye Su-jeong mean?
A2. It is 'DN,' derived from the first letters of Na Dae-il's name. It is a chilling mark left by carving his signature into a patient's organ during surgery 15 years ago.

Q3. Is the Korean version of <Doctor X> very different from the original?
A3. The overall basic structure (a genius freelance doctor vs. the power of a massive hospital) is similar, but the Korean version adds a lot of darker and more intense thriller and medical drama elements to the characters' relationships, past traumas, and the villains' narratives, offering a unique kind of entertainment!
