What is Korean Drama S Line About? – A Unique and Gripping Plot

The premise of S Line is unlike any other Korean drama you’ve seen. The story centers around an extraordinary phenomenon: red glowing lines appear above people who have had intimate, physical relationships with each other. These lines are visible only to a select few, and they instantly reveal hidden connections that were meant to stay secret.

The protagonist is a young woman with a special ability to see these “S Lines.” However, her unique gift loses its exclusivity when special glasses that grant the power to see these mysterious red connections start circulating in the black market. Suddenly, more people can witness the invisible webs of past relationships, turning everyday social interactions into tense confrontations.

Amidst this supernatural backdrop, the plot thickens when a shocking murder is discovered — one that may be linked directly to the secret lines and the people connected by them. As the story unfolds, viewers are taken on a suspenseful journey filled with twists, deception, and a hunt for the truth.
