Lee Soo-hyuk, Lee Da-hee, and Oh My Girl’s Arin Entangled by Desire in New Drama
The upcoming fantasy thriller drama S-Line has revealed its intense main poster, raising anticipation ahead of its premiere on July 11, 2025, exclusively on Wavve. Based on the popular webtoon by Murderer’s Puzzle (also known as A Killer Paradox) creator Kkomabi, S-Line explores a provocative premise: a red line—known as the S-Line—mysteriously connects people who have had sexual relations, exposing hidden truths and forbidden desires.
The poster features a visually arresting image of the three main characters—Lee Soo-hyuk, Lee Da-hee, and Arin—set against a backdrop entangled in red lines. Each character gazes in a different direction, visually reflecting the tangled emotions and complex relationships that drive the story.
Arin plays Hyup, a girl born with the rare ability to see the S-Line, who lives in isolation because of her power. Lee Soo-hyuk stars as Ji-wook, a detective entangled in both a murder investigation and the secret of the S-Line. Meanwhile, Lee Da-hee portrays Kyu-jin, a mysterious homeroom teacher whose lack of visible connections raises further intrigue. The poster’s bold contrast of restrained composition and vivid red threads hints at the dark secrets and emotional tensions that will unfold.
With its unique concept and star-studded cast, S-Line promises a gripping mix of mystery, fantasy, and psychological drama that pushes the boundaries of conventional K-drama storytelling.
