S Line is one of those dramas that keeps messing with your head in the best way possible. With every episode, the mystery deepens and the drama intensifies. S Line Episode 3 picks up right where it left off, and trust me, it doesn’t waste a single minute. Between emotional chaos, shocking betrayals, and the creepy glasses that show “S Line” (aka people who’ve had sex), this episode had me hooked till the end.

S Line Episode 3 Recap
The episode starts with Seon-A collapsing, and Hyun Heup is right there, clearly shaken. She’s rushed to the hospital, and when Detective Han shows up, Hyun Heup insists it wasn’t suicide. That one sentence sets off a whole chain of questions. Back at school, a teacher is suddenly missing. Everyone’s tense. Teacher Jung-woo drops a personal bomb, saying he’s canceled his wedding. Later, he shows up at his sister’s place to crash there for a week before heading to Canada.

Meanwhile, Seon-A is in the hospital, unconscious and hooked to machines. Hyun Heup quietly starts digging around, especially when she finds out Hye-yeong—Seon-A’s bully hasn’t shown up either. She’s suspicious of anyone wearing those round gold-rimmed glasses. And guess who finds a pair? Jung-woo. The second he puts them on, he sees those infamous red S Lines above people’s heads, and when he looks at Detective Han … let’s just say the guy has a lot of connections.

Han is still on his own investigation path. He meets Seon-A’s date, Ji-won, who’s just weirdly chill about everything. But he mentions that Seon-A got upset when she realized something of hers was missing. CCTV then catches Hye-yeong stealing her bag. Jung-woo, on the other hand, is going through a personal crisis. Turns out, his fiancée cheated on him with a friend. Then he discovers his brother-in-law is cheating too. He follows him to a hotel and, in a totally messy twist, thinks his sister is the “other woman.” But guess what? She actually is the other woman, and the man is already married to someone else who knows nothing. Messy doesn’t even begin to describe it.
Then another supposed? suicide” happens. Han reads the Will but believes the body was staged. It’s not adding up. He digs in his niece’s room and finds drawings of glasses and red lines. When he checks with Hyun Heup, she finally tells him: the glasses show who’s connected through sex — the S Line.
S Line Episode 3 Review
Episode 3 was straight-up wild. The story keeps getting more tangled, but not in a confusing way. It’s the kind of twisty drama that makes you shout at the screen — and I love that. Jung-woo’s storyline stands out in this episode. Watching him go through heartbreak, then accidentally blow up his sister’s life based on a misunderstanding, was intense. But the show did it in a way that felt real. You totally get why he thought what he did, especially since he was already hurting.
S Line Episode 3: Jo Han Chul
Detective Han is still the steady investigator trying to get to the bottom of things, even when everyone around him is ready to sweep it all under the rug. I like how the show isn’t rushing his discovery of the S Line. Now that he knows about the glasses, I’m curious how he’ll react when he sees himself through them. The red-line glasses are such a clever plot twist. They’re not just some gimmicky prop — they reveal dark truths and push characters to the edge. And there’s still a big question: who keeps planting the glasses in the perfect spot at the perfect time? Feels a bit too
S Line Episode 3:
The red-line glasses are such a clever plot twist. They’re not just some gimmicky prop—they actually reveal dark truths and push characters to the edge. And there’s still a big question: who keeps planting the glasses in the perfect spot at the perfect time? Feels a bit too planned to be random.
Final Thoughts
S Line Episode 3 was dramatic, emotional, and left me with more questions than answers, and I’m totally okay with that. S Line is doing a great job of blending suspense, emotional drama, and social commentary into one wild ride. The drama keeps introducing new layers and pushing characters into uncomfortable, revealing situations. With three incidents in three episodes, it’s obvious that something bigger is at play. And now that more people are finding the glasses, I can’t wait to see how things spiral from here.
If you haven’t started S Line yet, this is your sign to binge it. If you love unpredictable thrillers with a hint of dark humor and messy secrets, this one’s for you.
