The hit Korean drama S Line has officially wrapped up its six-episode run, leaving behind a plethora of reactions, theories, and questions. Starring Lee Soo Hyuk, Lee Da Hee, and Arin, the series drew attention for its provocative concept and dark fantasy tone. With elements of satire, mystery, and psychological horror, S Line dove deep into how people hide, fear, or succumb to their desires.
What is S Line really about?
The story revolves around Sin Hyeon Hop (Arin), a young girl born with the ability to see 'S-lines,' glowing red threads that connect individuals who have been sexually involved. After a traumatic past and the murder of her father, she lives in isolation until others gain the same ability through mysterious glasses. As more people begin to see the lines, hidden secrets surface, leading to chaos across her high school, with her teacher Lee Gyu Jin (Lee Da Hee) hiding a mysterious past. As greed consumes the wearers, she teams up with Detective Han Ji Uk (Lee Soo Hyuk) to halt this crisis and find the person behind it.
S Line ending decode: A cycle that never truly ends
The finale of S Line takes a turn many didn't see coming. In the final episode, Sin Hyeon Hop confronts Lee Gyu Jin, the woman who masterminded the distribution of the glasses and manipulated people's desires. Gyu Jin represents the embodiment of 'bad desires'—not just temptation, but the kind that pulls people into irreversible choices. Dressed like an angel in the real world, she lured individuals into surrendering their self-control under the guise of truth and transparency.
The climax unfolds on a rooftop where Sin Hyeon Hop fatally stabs Gyu Jin. But Gyu Jin's death isn't a clean ending—it becomes a trigger. Her blood rises into the air, transforms into red light, and bursts into glowing S-lines visible to the entire world. What was once a private curse becomes a universal revelation.
This shift reveals the show's core message: people often fear their past, but true collapse begins when they cannot accept it. The red lines, once symbolic of shame, now become a mirror forcing society to confront the hidden. Characters who couldn't come to terms with their own histories—like the teachers and the idol trainee—spiralled into violence, guilt, or denial. Meanwhile, those who did, like the detective, managed to remain in control.
Sin Hyeon Hop's arc also reflects this transformation. For most of the show, she believed she was responsible for her father's death, but her mother's confession changed everything. Her journey ends with her appearing emotionally stable, yet in the final moments, she hears Gyu Jin's voice again, implying that desire, guilt, and temptation never fully die. The return of a new red thread in her vision suggests that even if one source is gone, another always lurks within. Desires can't be erased. They can only be recognised, resisted, or accepted.
Fans' reactions: 'Wasted potential'
The bold concept of the drama, paired with its unique fantasy element, had fans raving early on. The ability to see red lines revealing past sexual encounters was unlike anything K-drama viewers had seen before. However, by the finale, many felt the story lost its grip. While the emotional depth and moral dilemmas were compelling, several viewers believed the plot would have been stronger had it focused more on the "killer line" narrative rather than expanding into a full-blown S Line universe.
Some users expressed that the final scenes felt unexpectedly comical, undercutting the tension that had built up over the episodes. There was also a shared sentiment that the show introduced too many subplots that were never fully resolved.
Over on the K-drama community on Reddit, one fan wrote, "What was the cult/dystopian ahh ending? Extremely disappointing. The concept of the S line had such great potential. The drama was such a wasted potential. They could have just gone with the serial killer storyline."
Another fan highlighted, "I could accept that they leaned a bit too much into the fantasy element in the last episode, but it felt too rushed and too open-ended for my taste. Especially after that 5th episode. I would consider this as a wasted opportunity."
"The concept is so cool they could've made many interesting seasons. But no, they wasted it," a third fan complained.
"I really liked the drama in the beginning, but what was that ending? Like seriously, after finishing the drama, I thought it was such a bummer. It could've been much better. Hated the ending and didn't expect it to end this way," one mentioned.

Will there be S Line season 2?
Though the ending provided emotional closure for several characters, it also introduced enough ambiguity to leave the door open for another season. The reappearance of the S-line, paired with Gyu Jin's lingering voice, hints that the curse—or perhaps the consciousness behind it—is far from over. Fans are already speculating on potential new storylines, including deeper dives into the origin of the glasses or a broader exploration of how the S-line affects society on a mass scale.
As of now, there's been no official confirmation about a second season. But with the series gaining popularity both domestically and internationally, the chances for S Line Season 2 remain strong.
