Lee Hyeon Jeong Aug 27 2025 10:57 am @d The actor who portrayed Seo Han Yu is Kim Jun Hyung.

paimo Aug 27 2025 10:42 am wtf with the ending? its baffled me, they try hard to build up the story but end up destroy them miserably. so dissapointing with the ending

Sunflower seeds Aug 11 2025 11:59 am Watched the show 'cause I love Lee Soo Hyuk oppa. He really deserves a solid main lead. This drama is so weird and ending gave me creeps. No offense but this drama wasn't upto the expectation.

Shin Aug 10 2025 7:45 am Episodes 1 to 5 - 10/10 Episode 6 - What The Hell Did I Just Watch?!

Perfect example of the when the ending of a movie/show ruins the entire experience I thought it was just me but 90% of the reviews on IMDb say the exact same thing Watch at your own risk

Mild spoilers ahead:

Q1: why did the demon do all that? I know she’s a demon but what was the end game? Chaos for the sake of chaos? Q2: what happened to Kim Hye-young? (the bully) Q3: assuming it was no accident (it would be a huge coincidence if it was), why did the demon kill Yoo Joon-sun? (Her “boyfriend”) Q4: why did the demon wait until she was 17 to realize her plan? Seems kinda arbitrary

Just an observation: the helmets are a silly touch, as if there aren’t any people who would see you put it on/take it off…

Nony Jul 29 2025 8:45 am Oh wow its something… the last ep was questionable?? But i read the comments that said the drama is a prequel to the webtoon. As in they explain on how the s line was introduced in the webtoon. I just felt that some scenes weren’t necessary. But okay?

Jojo Jul 27 2025 4:00 am Woah so this is the prequel of the original S Line webtoon! I think the ending might be confusing for people who didn't read the webtoon. In the webtoon, the S Line suddenly appears on the first episode. People were flustered. They wear helmets to hide their face because they are embarassed of their visible S Lines. Not showing the top of the heads of news anchors on the television become the norm, to protect their privacy.

I think 1-5 were so good. Episode 6 is also good, but I didn't expect the genre would suddenly switched to a full fantasy. I wish they had more bridging to prepare us for this, for example like hinting us about the homeroom teacher's mystery. I wish it has 7 or 8 episodes.

Overall I enjoy watching this!

Ideamachine Jul 26 2025 11:21 am It's amazing that SK writers have infinite ideas Who would have thought red line above the head and body count as an idea?

April Jul 25 2025 11:10 pm And I'm back after the finale. S-Line cemetery scene made me realize how Suzy and Arin look like each other. She's prettier without makeup.

Of course, the last episode followed the original plot of the webtoon, so the drama is like a prequel to the webtoon. It's a bit chaotic, but it really had a potential, 6 episodes is really not enough.

I've been watching Lee Soo Hyuk for years, but I think this is the first time to see him cry that much, and to see him defeated made me realize he's really more than his pretty face. Great acting everyone!

Disappointed Jul 25 2025 6:02 pm I was really interested in watching this kdrama until I saw what happened with Sun A. I can tolerate most terrible things but situations like hers make me really uncomfortable

d Jul 25 2025 12:07 pm do you know the "seo hanyu" actor's name?

Anonymous Jul 25 2025 10:05 am The ending doesnt make any sense lmao worst plot twist ever! 4/10. The beginning was good tho.

Ashley Jul 25 2025 8:52 am

SPOILER!!!!!*

Whatever happened to the bully that was with the teacher? He died in the car, but I don’t remember anything about her.

kdrummer Jul 25 2025 8:29 am SA'd, yes. I guess that was what I meant. And I hate that my theory is right.

James Jul 24 2025 10:40 am I think Kang Sun A might have been SA'd as a child.

A minor can't be an adult's "lover".

kdrummer Jul 23 2025 9:31 am Theories: Kang Sun-A's lover is her father. Yoo Joon-Sun is in cohorts with Lee Kyu-Jin. Someone is someone's mother... or some dumb twist like that. I don't know what the point of the story is yet, but my guess is that it's an extreme commentary of the hook-up culture.

Watermelon Jul 23 2025 8:39 am Why only 6 episodes

jeana Jul 22 2025 12:40 am i thought language teacher already died in his car (suicide??) why in ep 4 they said he is missing?

Luna M Jul 20 2025 7:50 am hi can someone explain to me the ending of eps3? so is it true that jungwoo’s sister is actually the mistress? or she just said that because her husband chose that woman?

Bea Jul 20 2025 7:34 am Lee Soo Hyuk is freaking gorgeous here, he reminds me of seventeen Jeonghan. Another male actor added to my crush list lol. Guys with androgenous beauty are really my style.

Also, congrats to Arin! Her first main role big project as an actress!

AMAN Jul 19 2025 2:31 am Dammm.... the twist in the ep03 was quit unpredictable. i like the idea that they have one different story line going along with the main story.. very unique concept

AMAN Jul 18 2025 9:38 pm that actress Lee Eun-Saem (Kang Sun-A) is either being pushed from the building or watching someone being pushed from the building since her last 3 dramas...

Justitia Jul 18 2025 3:46 pm Always here to support My Queen Lee Da Hee ! Villian or not always gonna support her roles and the Lee Couple is so sexy together. Although if they are ending together or not, fans are ready happy to see them both cast together !

April Jul 18 2025 12:45 pm This drama have 6 episodes, but I'm so intrigued I've search for spoiler only to get none which is good. So they actually deviate from the original plot. This is actually a good idea, on the webtoon, there's no glasses and everyone can actually see the red lines, not innate like Arin, but mysteriously appeared and gone all at once.

So I really have no choice but to wait for episodes 5 and 6 hehe minus the s*x part, it's really a promising story. The production might be punching in the air now for making it 6 episodes only.

Ashley Jul 18 2025 8:48 am So far, I find this drama boring and it lags. However, episode three was interesting. Personally, I feel like Koreans are just too nosy and always trying to be in other’s business. Who cares about who’s sleeping with who. Honestly, this drama has everything I can’t stand about Korean culture, which makes this very hard to watch. The hive mind / conformist mindset, the attempted murder disguised as “bullying”, the unnecessary hierarchy, and the idiot police upper management who are completely incompetent.

TTO Jul 17 2025 1:41 am I feel has something to do with those glasses.

AMAN Jul 17 2025 12:14 am Lee Kyu-Jin character seems fishy to me.. i feel she has something to do with those glasses..

Marga Manuel Jul 16 2025 1:06 am Super duper highly recommended! This first 2 episode will give you really an intense feelings and the story line was very interesting! Must watch this...

Gee Jul 15 2025 9:35 pm I recommend watching this drama. The plot is different from the others. In my opinion, maybe the teacher is the mastermind, maybe she can also see the line.

Molly Dash Jul 15 2025 9:36 am A Must See Drama !!!

Paula Jul 14 2025 3:06 pm The drama has an unusual, strange approach to skills, but also an interesting plot. I'll be watching until the end and hoping for a second season. The drama's flaw is Kang Sun-A, who's an irritating character. Her uncle helps her and raises her, and it pisses her off? Sure, her classmates are mean, but they're known to be bad people. Kang Sun-A, on the other hand, is supposedly a positive character and a victim, but she's annoying.

miho9 Jul 14 2025 1:33 pm I actually watching this right now ep2 so exciting more s life who with detective charr !

pinkonmonsta Jul 14 2025 9:06 am I thought Arin was Roh Jeong Eui at first... looks so similar

player 457 Jul 13 2025 1:09 am Bruh I watched this without looking at synopsis, I was shocked at the intro but the first 2 episodes were interesting. Highly recommended

M Jul 12 2025 5:07 am Arin kinda looks like Suzy here.

leon Jul 11 2025 3:46 pm Just finished watching the first two episodes. I am glad I didn't have to wait 2 years to watch this.. hope people below me and the one who waited for that long know this just released today :)

thrillme Jun 08 2025 11:02 am definitely seems like it was tossed.
