Seoul: The upcoming fantasy thriller "S Line" departs from its source webtoon by limiting who can see the story's mysterious red lines, director-writer Ahn Joo-young said Monday.
According to Yonhap News Agency, the series is based on the popular webtoon by Kkomabi, known for Netflix's Korean original series "A Killer Paradox." It depicts a world where a visible red line-the "S Line"-appears above people's heads, connecting them to those they have had physical relationships with.
The story centers on Hyun-heup, portrayed by Arin of the girl group Oh My Girl, who was born with the innate ability to see the lines. She is joined by her high school friend, Sun-ah (Lee Eun-saem), whose world is turned upside down after acquiring mysterious glasses that enable her to see the lines.
The ensemble cast also includes Lee Soo-hyun as Ji-wook, a determined detective investigating a murder, and Lee Da-hee as Gyu-jin, a teacher whose friendly demeanor hides a piercing gaze.
Ahn, a big fan of the original webtoon, noted that changes were necessary to adapt the concept for a drama series. "In the original, the red lines appear on the head of everyone, but in the drama, only a few people can see them and often with the help of special glasses," she explained during a press conference in Seoul.
She further elaborated that the main theme of the series explores how people would change if they could suddenly see those lines, describing it as being "fundamentally about people and their desire."
"S Line" has already generated a lot of buzz ahead of its local release after winning Best Music at this year's Cannes International Series Festival (Canneseries) in April, where it held its world premiere. This award marked the second time a Korean series has won at Canneseries, following "Bargain," which won Best Screenplay in 2023.
"I was incredibly honored," Ahn said, reflecting on her drama director debut with "S Line." "At the premiere, the audience filled the auditorium, and they applauded when it was finished. I was so moved by the response," she recalled.
The six-episode series, "S Line," will premiere this Friday on the Korean streaming platform Wavve.
