What Is S Line About?

Social. Sex. Secrets.: The S-Lines (stylized as S Line) blends dark fantasy with crime thriller elements. The drama imagines a world where people’s past sexual relationships appear as glowing red lines hovering above their heads — called S Lines.

At the center of the story is Hyeon-heup (played by Arin), a high school student who has been able to see these S Lines since birth. When special glasses are developed that allow everyone to see the same connections, hidden affairs, betrayals, and shameful truths come to light, shattering lives and relationships.

According to Prime Video’s synopsis, the drama explores themes of desire, betrayal, privacy, and morality, raising haunting questions about how much of one’s secrets should remain hidden.

Cast and Characters of S Line

The star-studded ensemble cast adds depth to this provocative narrative:

• Lee Soo-hyuk as Han Ji-wook, a detective entangled in cases linked to the S Lines.

• Arin (Choi Ye-won) as Hyeon-heup, the student with the rare ability to see S Lines since birth.

• Lee Da-hee as Gyu Jin, a teacher with no visible S Lines but a mysterious past.

• Lee Eun-saem as Kang Seon-ah, another student whose fate ties into the central mystery.

• Kim Dong-young as Oh Dong-sik, Ji-wook’s junior officer.

Together, they navigate a narrative filled with dark secrets, blurred moralities, and shocking revelations.

Global Recognition and Controversy

Based on a popular Naver webtoon, S Line drew massive attention even before release for its daring premise. The show premiered at the 8th Cannes International Series Festival, where it won the Best Music Award.

Its treatment of sexuality and relationships through the eerie metaphor of red lines has been labeled both “bold” and “controversial,” sparking debates among viewers and critics.
