The new K-drama S Line, adapted from a successful webtoon, promises to be a fantastic thriller as original as it is disturbing.

The plot is based on a singular concept: red lines, visible only to some, appear overhead, linking individuals who have had intimate relationships. These invisible threads, called S Line, suddenly reveal truths that many would rather hide.
The teaser begins with Hyun Heup (played by Arin from the band Oh my girl), a high-school student who has been able to see these lines since birth. In voice-over, she confides that she feels cursed. The images that follow reveal a tangle of intimate and embarrassing connections, bringing the deepest secrets to light.
The detective Han Ji-wook (Lee Soo-hyuk), at the heart of a murder case, discovers a wall covered in these red threads and conjures up a mysterious pair of glasses linked to this phenomenon. Last but not least, Gyu Jin (Lee Da-hee) warns: for some, these revelations will be a flaw, for others, an opportunity to be exploited... A promising drama mixing tension, desire and disturbing truths.
S line is a 6-episode series to be broadcast in July by Wavve.
