Lik Feb 24 2026 2:49 am Deserve the low ratings . So bad

laala Oct 22 2025 6:46 am LBY's worst drama T.T I really enjoyed drama Agency

Chamonks Sep 24 2025 10:28 am I had high expectations for this drama because I like this genre, but overall the drama was quite flat. What made it even worse was that the translator used Chinese names for the characters, which made it hard to identify them. I cried a few times, and I will watch it if it is given a second season, but since the ratings aren't that good, it is very unlikely.

Saranghae Sep 22 2025 2:31 pm I just started watching the series, I'm on the first episode, what bothers me is the hairstyle of the actress in the main role (Lee Bo-Young), I really don't understand why she has to have that messy hair and directly in her eyes?!! I wonder what the hair and make up designer wanted to demonstrate?? I like this actrice very much but watching her with the hair in her eyes all the time annoys me and ruinate the pleasure of watching the series?‍♀️

Silvia Valli Sep 16 2025 5:52 pm It's a good drama but it didn't get high ratings. The plot is a bit depressing, and many people can't deal with the situation presented. I liked it very much. People should have an option.

sf Sep 14 2025 3:18 am I wait for season 2.

Seliya Sep 13 2025 9:44 pm Watched it on illegal sites, but stopped at 3rd episode, I think i know reason why no OTTs take this drama. Interested because theme is euthanasia but turn out to be so controversial

susu Sep 13 2025 10:07 am This drama is good but the ending was a cliffhanger. It should have season 2 to elaborate Gu's sister character.

Eli Sep 05 2025 3:49 am I expect this drama to be controversial and it's obvious on how the rating drops. But it's really a good one, Boyoung script/drama choices were never questionable for me. But aside from physical terminal illness, I hope they include those battling with mental illness as well, it's even legal on other countries. Anyway, I really believe people should have their own choice to leave, than prolong the suffering.

Whatever Aug 29 2025 2:13 pm Wow so I’ve only finished ep 2 (have to watch this online in websites with not-so-great subtitles because none of the sreaming services have it ?) but I’m so in love!

To be fair I only started watching for Lee Min Ki, but this show is actually really really good? Like I’m totally invested in the doctor lady and actually like her character a lot, which is rare for me as I feel like FLs in kdramas aren’t well written but I’m actually super invested in her and her story going forward, I also really like the dude she does the euthanasia with, he brings a nice subtle comedic element which I really felt in ep 2 with the high school kid and the motorcycle. On top of that, I usually loathe romances of any sort, but I’m finding myself kind of liking the idea of a possible one between the main leads, it just kinda works and feels right, at least for now since it’s still early on. And the villains (the cops), are also great because wow I really hate them lol.

I really was not expecting much from this show but I was actually pretty blown away from the first two episodes. Solid characters, solid story.

I also want to say, the topic of the show may be controversial but it is one worth talking about and I’m so glad to see a show portraying it. For me, s***ide in general is a very personal topic for me and I really love the things this show has to say, it’s also very emotional at times for me but I love the different cases and people they deal with.

I hope some streaming service will pick this up as it’s very underrated I feel like and it deserves so much more attention, I’d also love to be able to see it on one but if it ever happens by then I’ll probably be finished with it ?

haha Aug 24 2025 1:54 pm Honestly, the most useless and selfish characters in this drama are the police. They literally have nothing better to do than arrest Mary and her friends without any evidence, throw accusations around, and lock them up for interrogation (especially Bu Cheol-Su). Like, hello? can you find the actual proof first?! stupid. poor story

Ena Aug 18 2025 2:03 am I am So excited to see this drama, does anyone know when it may be released in the US?

Mina Aug 16 2025 3:58 pm Actually “aid in dying” is only legal in 10 US states and each has its own interpretation and rules to follow. So hospices do not routinely help people to die.

Jillibean Aug 12 2025 9:00 pm Aren't there hospices in South Korea? In American hospices they routinely give patients pain relieving drugs, plus drugs to make them unconscious and to die peacefully while sleeping. Intense pain will eventually kill a patient anyway so why make them suffer needlessly?

Dee Aug 09 2025 2:46 pm I'm surprised no one is watching this show, it's quite amazing. They aproach a difficult subject very carefully, it's hard to watch and very emotional. Amazing cast too.

Duke hyda Aug 07 2025 5:25 pm A long time fan and watcher of kdrama, I have seen glimpse of episodes 1 and 2 hope this isn't woke

Star Aug 03 2025 10:53 am Lee bo young messy hair giving the same vibe as park eun bin in hyper knife

Bunna1704 Jul 13 2025 9:21 pm Mary Kills People is highly anticipating. Strong main leads and with bunch of great supporting actors. This is serious drama. Teasers were thrilling and suspenful. They made some differences from the original drama so we cannot predict how the story goes. Excited for Lee Boyoung and Lee Minki's pairing, can't wait!!

bucky Jul 04 2025 5:31 am Lee Sang-yoon cameo? watched their pair in two dramas before

Happy Jun 24 2025 4:26 am Lee Min Ki has a remarkable ability to bring characters to life in a way that feels incredibly real and authentic. I'm sure he will do a great project :)

Woah Jun 20 2025 7:32 am lee min-ki detective again lmao
