The mystery-thriller K-drama S Line, starring Lee Soo Hyuk and Arin, is racing toward its gripping finale. As episodes 5 and 6 approach, fans are bracing for high-stakes revelations, dark twists, and the final unraveling of its central mystery.

When and Where to Watch S Line Finale

The final two episodes of S Line will stream on Wavve on July 25 at 11:00 AM KST (7:30 AM IST / 10:00 PM ET). Viewers can expect the conclusion to deliver both emotional weight and shocking developments as officer Han Ji Wook gets closer to the truth.

Recap: What Happened in Episodes 1 to 4?

The series follows Sin Hyeon Hop (Arin), a high school student who gains access to a unique pair of glasses that reveal glowing red lines above people's heads, indicating their number of sexual partners. While she initially uses the power to help others, things spiral out of control when another student, Kang Seon A (Lee Eun Saem), obtains a similar pair and misuses them to blackmail a teacher engaged in an inappropriate relationship.

This leads to tragedy—Seon A is found dead, having been pushed off the school rooftop. Her uncle, detective Han Ji Wook (Lee Soo Hyuk), takes over the investigation and soon discovers the disturbing truth behind the glasses.

What to Expect in Episodes 5 and 6

In the finale, Ji Wook dives into a sensitive r*pe case. The victim, unwilling to come forward, denies any abuse—but the mysterious glasses reveal a red line above her head, indicating otherwise. Ji Wook must uncover who the line leads to in order to bring justice to the victim.

Meanwhile, suspicion falls on homeroom teacher Lee Gyu Jin (Lee Da Hee), as Ji Wook investigates the origins of the glasses. Another twist awaits as a male teacher also acquires the glasses—potentially using them for sinister purposes.

As Ji Wook edges closer to identifying his niece's killer, viewers can expect a suspense-filled conclusion packed with emotional tension and moral dilemmas.
