S LINE ties people together in eerie live-action adaptation trailer

Sex might be a behind-closed-doors matter, but S Line is kicking that door wide open.

Wavve has unveiled a new trailer for its upcoming live-action drama adaptation of S Line, starring OH MY GIRL’s Arin and actor Lee Soohyuk. The high-energy teaser reveals a world where red lines appear above people’s heads to indicate their number of sexual encounters. These lines are invisible to most—except for high school student Hyun Heup (Arin), who can see what’s called the “S line.” Meanwhile, detective Han Jiwook (Lee Soohyuk) stumbles upon a disturbing clue in the middle of a murder investigation: a wall completely covered in those red lines.

Two teaser visuals accompanied the trailer. One features a cryptic, chaotic spread of lines obscuring most of the poster, while the other offers a clearer look at the main cast.

Lee Da Hee will join the cast as Gyu Jin, a quirky high school teacher, while Lee Eun Saem plays Sun Ah, Hyun Heup’s classmate and Jiwook’s niece. The drama is already making waves internationally, having won Best Music in the long-form competition at the 8th Cannes International Series Festival in April.

Based on the webtoon by kkomabi, S Line explores the mystery behind these red lines, which seem to be linked to sexual activity, but may carry deeper meaning. The original webtoon premiered on Naver Webtoon on December 16, 2011, and concluded on November 15, 2012, with 49 episodes. Although S Line doesn’t have an official English translation, international fans can check out A Killer Paradox, another of kkomabi’s works, which is available on WEBTOON and was also adapted into a Netflix series.

S Line premieres on Wavve on July 11.
