Premiered on July 11, the Wavve original drama explores a world where red threads dubbed “S lines” become visible between people who’ve had sexual relations. These mystical lines reveal not only hidden connections but also dark desires and dangerous truths. In the drama, Lee Soo-hyuk stars as Han Ji-wook, a detective and the uncle of Seon-ah (played by Lee Eun-saem), who mysteriously falls to her death. Ji-wook, armed with glasses that can see the S lines, sets out to uncover the truth behind her tragic end.
