## Synopsis

S Line (2025) is a South Korean science fiction mystery miniseries created by Ahn Joo-Young and Kkomabi for wavve, adapted from a webtoon and produced by Sidus. Lee Soo-hyuk plays Han Ji-wook, and ARIN plays Shin Hyeon-heup, while Lee Da-hee, Lee Eun-saem and Kim Dong-young round out the principal cast across six episodes of roughly fifty-five minutes each. The protagonist is a young woman who can see mysterious red connections between lovers, a secret gift that has always set her apart. The engine of the story is her gradual discovery that the advantage is no longer hers alone, as special glasses granting similar sight surface on the black market and pull a widening circle of people into a web of desire, exposure and leverage. Each episode follows several characters who are directly or indirectly tied to those red lines, so the drama lives in the dynamics between them and in how each one uses the glasses. The show is a single compact season with a clear limited-run shape rather than a sprawling saga. Its register is sleek, provocative and unsettling, with a social thriller edge that treats private intimacy as something to be seen and traded. Fans of Sweet Home and Black Mirror will find resonance in its blend of supernatural premise, moral unease and modern surveillance anxieties, set in contemporary urban South Korea.
