After seeing the red lines all over in the social media, you may wonder why on earth red lines are trailing over people's heads. The trend on social media is simple and blunt—"More “red lines = more body counts”. That means the number of people you had sexual connections with are now visible to people. In blank eyes it might seem funny and pointless. But what if the actual story behind those red lines is far more disturbing, unsettling, and far more human?
This is the story the director Ahn Joo-young is trying to tell us in the “S-LINE” k-drama. This Six episode ongoing series premiered on July 11 with its four episodes running on Wavve. This thriller series is going viral for all the wrong reasons in Bangladesh, hiding its actual message.
S Line takes place in an uncertain future in which a new technology—or possibly a curse—causes red lines to emerge over people's heads, physically connecting them to everyone with whom they have had a sexual experience. Some people are born with the ability to see these lines, while others employ "S Glasses" to access a visual map of their intimate history. However, the show does not stop at shock value. Instead, it focuses on the ethics of visibility, privacy, obsession, and society criticism. What happens to human connections when our most intimate decisions are on public display? What happens to women, teachers, teenagers, and law enforcement officers in a society when privacy is no longer a right but a luxury?
The story started with a teenage girl named Shin Hyun-heup, a high school student who was born with the curse of seeing red lines above people's heads. On the other hand, the high school teacher named Gyu-jin with no red lines on her head builds mystery and suspense through her actions. The main attraction was brought by the actor Lee Soo-hyuk, who played the role of detective Han Ji-hook, who is connected to the murder cases, which are possibly linked to the S-line phenomenon.
The real suspense rises, however, not in the series thriller mechanism, but in the characters moral integrity and emotional aspects. How do people treat each other when their deepest, darkest secret becomes data? Can empathy be replaced by judgement?
This thriller series pushes the viewers to confront unsettling or disturbing truths: Are we really ready to learn and see everything about each other? If so, what will be the price for it?
In just six episodes, S Line has been shown to be more than a gimmick. This series is a timely and thought-provoking exploration of surveillance culture, psychological trauma, gender politics, and the delusion of transparency. So next time a meme pops up on your screen with this red line, it's time to rethink.
