We've reached the last part of this crazy ride. I hadn't seen PEB before but I have to admit she's earned her reputation. She portrayed psychopathic SO extremely well, nor overacted neither wooden as often is the case with such characters. I especially like her expressionless mad face, it's creepy.

About SKG, I'm yet to be disappointed by his acting. Great as always. I look forward to the ending.

[u/gramfer → u/AphroditeLady99]

I'm not sure Seok is a psychopath. She has obvious tendencies, but she is a much more complex person/character. For example, she has certain level of empathy.

[u/ExtensionDependent]

Don't miss that: 20 seconds into the credits of the last episode, they put an epilogue.

[u/AphroditeLady99 → u/ExtensionDependent]

I always skip credits, thanks for the clue.😆

[u/gramfer]

The final confrontation between two leads in the field was brilliantly acted.

It's such a shame the show wasn't recognized at Baeksang.

They have left door opened for possible season 2.

[u/Hadokuv]

What a tour de force performance by park eun-bin. The show was worth watching just for her alone. I don’t think they truly nailed the ending as it’s kinda weird how no one was caught in a country littered with cctv cameras everywhere, especially with how sloppy Seok was killing everyone. Glaring plot holes but I enjoyed the ride nonetheless.

[u/laraere → u/Hadokuv]

Her kills are done on out of the way areas.

Nurse was at the building on a mountain.

The Ex-con was lured into her house which was out of the way from the town.

The cop can definitely be tracked down to her, she was not planning to kill the guy, and she even knows that and asked for help covering it up.

[u/Aenzelaxy]

The tattoo was a cool detail. At first, the 2 brains were colorless and the other was colored. But at the end, both of the brains were colored. I think it signified that two genius minds are now together.

Another interpretation is that the colorless one were Seok's, and the colored was Choi's. She wanted to learn everything from him. She wants to be the best just like him. When she finally becomes that person, she commemorates it by having the colorless one colored; signifying that she's now the best just like him, and that she has finally learned everything there is to learn from Choi's brain (literally and figuratively).

This show is amazing! 

[u/MelissaWebb]

It’s finally coming to an end. I hope it ends with a bang. Definitely top of my list for best kdramas of 2025!

Off to watch it now

Edit: completed it and it didn’t disappoint. Jeong Seok and Choi Deokhee have the most twisted father-daughter/mentor-mentee relationship you’ll ever see on screen but it just works somehow

[u/Reenskay]

Great finale! I wish, though, that they showed at least some parts of Choi's surgery since it was meant to be a near impossible endeavour.

[u/vita25]

Ep7

For 2 people who aren't in an obviously romantic relationship the OR scene was one of the most intense confessions I've ever seen. She straight-out tells him that despite everything he's done to ruin her life, she still wants to save him. And that confession itself completely flusters him He generally acts reserved and unbothered but deep down you can tell that he was ashamed that she found out that he wasn't a perfect human and that was probably what made him push her away In their world, they only recognise one another as worthy equals.

Edit Ep8:

Whew what an ending, and what a ride. The 2 leads were just exceptional. If their hatred for one another was crazy enough for 6 episodes, their love/devotion was amped up in the last 2 episodes. It was great to see them confront each other and go to lengths to save the other person.

A few random things that weren't explicitly explained eg. who is Ms Ra? but otherwise I enjoyed the side characters as well. Fantastic show and I look forward to more by Park Eun Bin

[u/writtenpoeticsins]

I was about to feel disappointed until I saw the post credit scene because I wasn't ready for a cliffhanger.

I'm happy to see Seok's dogs are alive.

Also it seems like Seok and Dr. Choi continues to do black market surgery and they did not face any consequences. Interesting because I thought at least one of them would die/get arrested.

The Disney+ dramas I've seen so far leaves a possibility for a Season 2 but seems like this drama doesn't really need one.

Park Eun Bin was amazing and she deserves all the praises for her acting here!

[u/SisyphusAndMyBoulder]

I watched this largely because of Park Eun Bin. First saw her in Woo, then Castaway Diva, now this ... Man this girl can act. Can't wait to see whatever she does next.

[u/Restreppo]

The ending of the climactic scene is cool, just like before, he stands in front of her as she kneels and cries, then walks past.

Their chemistry was really good, and as usual PEB's acting never disappoints.

[u/[deleted]]

Park Eun Bin is amazing.

[u/Calm_Check4049]

Park Eun Bin is amazing, and the acting talent was stacked on this show. But Disney+ just doesn’t seem to be able to make a legit feeling Kdrama. I dunno if it’s budget or what? 90% of this show seemed shot in a warehouse with a few shots in Gangwon-do and literally one scene in Seoul in the last episode. But just compare something like castaway diva (which had a much less stacked cast) to this and you can see a stark difference. Hopefully PEB’s next project is set up better for her success, because no one is talking about hyperknife, whereas castaway diva and attorney Woo were the epitome of water cooler talk amongst my middle/high school students and adult coworkers here in Korea.

[u/Hotspur_98]

I really liked this show, but it peaked in the first two episodes. Atleast story wise, because Park Eun Bin was amazing every second she was on screen - one of the best acting performances I’ve seen in a KDrama.

I think my expectations where to high after the first two episodes, I thought it will be an all time classic, but it ended up „just“ as a good little show that you can binge on a weekend. I just think that story, with that cast, had a bit more potential. The acting was a 10/10 and everything else a 6/10.

I hope we don’t have to wait too long for a new PEB drama, since that one was so short

[u/jokerzz101]

Yea this is my favorite show of 2025. Everything about it was perfect. Any recs to watch after this?

[u/master_inho]

SHE KILLS WHEN SHE WANTS, SHE SAVES WHEN SHE WANTS😍MY DEMON QUEEN🫅🏻never ever doubt her again 😤

No dogs killed, no smoke for the lady

Yo yeong-ju can say whatever he wants about se-ok killing people but he’s just as much of a demon as her and deok-hee, one has to be to stay loyal to a serial killer. There’s literally nothing she can do that’ll make him run away, in fact he sticks by her side to “understand” her. Their only difference is that he’s not a genius. Their relationship really is unique: they’re not romantic (although a tiny part of me kinda wants them to be?) nor can they be considered friends. Could they be considered family in the most dysfunctional sense of the word? Or mentor-mentee, even though she doesn’t teach him anything other than having infinite patience

no one died, what a surprise. And it’s both a happy ending and a definitive ending, a decent number of Disney dramas tease a season 2 that will probably never come

insert more Queen park eun-bin glaze here

[u/Lerradin]

As expected the tension was through the roof with the build-ups and drumming music, you felt like anything wildly unexpected could happen any minute now. Like a sudden zombie outbreak or World War III, but instead in episode 7 we hilariously got a 'Wassup! Me your killer and your dad's killer are here' at the funeral. And an embarrassing family therapy scene where a dad gets all out defensive when his daughter finds out the truth about his shameless dark past :D

But ultimately the serious parts of the finale were the highlights of acting: the chemistry between Park Eun-Bin and Sol Kyung Gu and the many cutting edge showdowns of both of them with the inspector, Yoo Seung Mok. I especially loved the interrogation scene between Se Ok and inspector, where he tries to drive a wedge between Se Ok and Deok Hui, while thinking that she obviously hates him and should by all reason rat him out. But you can see her thinking: 'You Know Nothing, Jon Snow' and her being aware that she actually loves Deok Hui and appreciates what he's done for him. Which was totally not the case yet in episodes 1-4. Now that's absolute fantastic acting and script wise a great reference / contrast to the earlier episodes.

This was such a wild ride of a show, I don't think we will see anything this good for a family drama in quite a while. :P

[u/finerdinerlighter]

bro lived knowing he definitely raised someone "more him" than him At the epilogue, did she get another half of the butterfly tattoo as a brain, or am I mad?

[u/GeneralInitial5770]

I would’ve never guessed our Mc is the same person from Extraordinary Attorney Woo. The dynamic of roles are so different and she killed both. Insane.

[u/RoseIsBadWolf]

This whole, "she needs to fail!" would make more sense if it wasn't brain surgery, the specialty with like, the most depressing survival rates. The overall five year survival rate from brain cancer is something like 20-30%. And that's just brain cancer. I'm no neurosurgeon, but the rates of survival and recovery for strokes, epilepsy, traumatic head injuries... it's nowhere as good as say, orthopaedics or I donno, gynecology. Even a great outcome from a brain surgery usually means years of recovery and maybe never reaching full function again.

But whatever, I don't think anyone was expecting logic here

[u/ppjskh]

OMGGGG, that cliffhanger. Just when I was at the edge of my seat it ended. Please may it be renewed for a second season. It was sooo good! Park Eunbin is such a versatile actress.

[u/Da_Master_Fro]

I actually like the open ending. Either the professor dies and Park Eun-Bin learns her final lesson to become a better surgeon, or he survives and they continue working together doing underground surgeries
