Overview

• Adapted from Kkomabi’s 2011 webtoon, the six-episode thriller centres on Shin Hyun-heup’s ability to see red lines linking people who have had sexual relations through special glasses.
• Wavve released episodes one and two in mid-July and will roll out the remaining four on a weekly schedule through early August.
• Early reviews commend director Jooyoung Ahn’s stark portrayal of privacy erosion, technological paranoia and societal surveillance.
• Red line memes—ranging from clips of Lee Soo-hyuk’s character to user-generated edits of pets and pop culture figures—have amassed millions of views and likes on TikTok and X.
• Exclusive streaming on Korea’s subscription-only platform Wavve has limited immediate global access but has not slowed the show’s online footprint.
