The K-Drama series S-line premiered on July 11, 2025, following its debut at the 8th Cannes International Series Festival. Based on a popular webtoon, the series intertwines the lives of four central characters: detective Han Ji Wook portrayed by Lee Soo Hyuk, homeroom teacher Gyu Jin played by Lee Da Hee, student Hyun Heup from Oh My Girl, and Seon A acted by Lee Eun Saem. The narrative explores the disturbing concept of connections between individuals, represented as red lines, which become visible through special glasses worn by some characters.
The plot takes a dark turn when Seon A discovers the glasses, leading to a tragic accident that leaves her hospitalized and reliant on a respirator. As Han Ji Wook, her uncle, investigates her fall—initially deemed a potential suicide by authorities—he stumbles upon the glasses, which he uses in a quest to solve a series of murders.
In a shocking twist, Han Ji Wook learns that the red line connecting Seon A to another individual leads back to his own father. This revelation implies that his father has committed an unspeakable act against his granddaughter. The dramatic moment culminates in a violent confrontation between the detective and his father, leaving viewers both shocked and disturbed.

The intense storyline has sparked significant reactions on social media, with many viewers expressing their discomfort and drawing parallels to real-life abuse cases. One viewer tweeted, “Oh the mother of plot twists… I’m disgusted but not surprised… Men are f*cking trash in this drama.” Another remarked, “The hardest pill to swallow is that this really happens in real life. Most of the time it’s at home, and it’s someone in the family you thought would protect you, not hurt you.”
Conversations surrounding the show have highlighted the importance of awareness regarding such sensitive topics. Many viewers are calling for more open discussions about familial abuse, emphasizing that these stories, while fictional, resonate with numerous real-life experiences.
