S Line: From Getting Recognition At Cannes To Breaking Records On Wavve

For 12 consecutive days, Wavve, a popular OTT platform, has seen the highest number of subscriptions since S Line premiered on July 11. In the second week, with episodes 3 and 4, the drama garnered the No. 1 spot based on the viewership count and total watch time within Wavve’s drama category. On July 19, after the broadcast of episode 4, it broke Wavve’s 2025 daily paid subscribers’ count and proved that this series is here to dominate the small screens.

Based on the popular webtoon of the same name by Kkomabi, who also wrote Netflix’s The Killer’s Shopping List, the drama was officially invited to the long-form competition at the 8th Cannes International Series Festival, and in the Best Music category, S Line was the first Korean Drama to win the award.

The drama has the signature impact of Kkomabi’s world-building theme and suspense. Although S Line sparked a lot of buzz for having bold and nude scenes in the initial phase and has been rated 19+, viewers are loving the plot and the twists and turns. Talking about the depiction, the director of the drama, Ahn Joo-Young, said during a press conference (via KBIzoom), “It was difficult to visually depict a world where everything is covered by the S Line. We maintained the universe but reimagined it through the lens of glasses as a storytelling device. I wanted to explore how humans change when they gain the ability to see the S Line.”

S Line features a stellar cast, including Lee Soo-Hyuk, who plays the detective of the drama, Han Ji-Wook, Lee Da-Hee as Kyu-Jin, a mysterious high school teacher, Arin as Shin Hyun-Heup, who can see the lines since birth, and Lee Eun-Saem, who portrays the high school student Kang Seon-Ah, who starts to see the lines after getting the special glasses.

The limited six-part series will release its final two episodes on July 25. Have you started watching it? Let us know.
