Promoting S Line at Cannes
The Cannes International Series Festival, held from April 24 to 29, 2025, invited S Line as the only Korean drama in its long-form competition category. The series, directed by Ahn Ju Young and produced by Sidus, premiered globally at the festival before its official release in Korea later in 2025.
S Line is based on a popular webtoon by Little Bee. It tells the story of mysterious red lines, called “S Lines,” that appear above people’s heads. These lines connect individuals who have had physical relationships, exposing private details and causing social chaos. The drama explores themes of privacy, judgment, and human connection in a satirical thriller format.
Lee Soo Hyuk stars as Han Ji Wook, a charismatic detective determined to uncover the truth behind the S Lines. His performance is expected to showcase his signature charm, seen in past dramas like Doom at Your Service and Tomorrow. Arin plays Hyun Heup, a high school student who has seen S Lines since birth. Her role marks a shift to a darker, more complex character compared to her previous work in Alchemy of Souls.
Lee Da Hee also stars as Gyu Jin, an eccentric high school teacher. The trio’s casting has generated buzz for their striking visuals and acting talent. Rookie actor Lee Kwang Hee joins as Jun Sun, a classmate of Arin’s character with a romantic interest in her.
