The red string theory has always symbolically empowered the heartfelt belief in the existence of soulmates. However, this year, South Korea put out a psychological crime thriller series that forever perverted that vision to make way for a bold switch-up no one saw coming. That daring, or as some like to call it controversial, move was made by none other than the K-drama entitled S Line.
Starring Lee Soo Hyuk (Tomorrow), Oh My Girl’s Arin (aka Choi Ye Won), Lee Da Hee (The Beauty Inside), Lee Eun Saem (All of Us Are Dead) and Kim Dong Young (River Where the Moon Rises), the six-part series originally premiered in July 2025.
Despite its limited release on the South Korean streaming platform Wavve, the show went on to soar to the stature of a global sensation. Based on a Naver webtoon, it stole the spotlight at the 8th Cannes International Series Festival this year. After securing a historic Best Music Award win at the prestigious international ceremony, the show is now coming to our screens at home in a bid to win the hearts of its Indian audience next.
Thanks to Amazon Prime Video India’s relatively new add-on subscription to Channel K, fans back home can now get a good look at the mini drama series that startled everyone due to its subject matter even before its official debut. With all its red lines-filled chaos, the Lee Soo Hyuk-starrer chases dark secrets while especially playing mind games like never before.
S Line K-drama India release schedule
Having premiered on Indian OTT on September 10, the first two episodes of the viral K-drama are already live on Prime Video India’s Channel K. Meanwhile, the remaining episodes will be released on a weekly basis. The release timings for all episodes remain 12 PM.
S Line plot
According to Channel K, the series log-line reads: “Hyeon-heup has been able to see the mysterious ‘S lines’ since birth, a secret only she could perceive. But when the special glasses allow others to see it too, long-buried secrets and hidden connections surface, pulling her into a web of desire, betrayal, and dangerous truths in this haunting thriller.”
S Line K-drama characters
- Lee Soo Hyuk is Han Ji Wook – a detective and a “flirt”
- Lee Da Hee is Lee Kyung Jin – the “mysterious” high school teacher
- Arin is Hyeon Heup – the student who “sees the S lines”
- Lee Eun Saem is Seon Ah – a student and Ji Wook’s niece
- Kim Dong Young is Oh Dong Sik – Ji Wook’s junior
As always, there’s a lot more to the story than what appears on the surface. Do the red ‘S lines’ merely dictate one’s sexual history, or do they tell a different story altogether? Countless other theories are on the rise about them. Want to know the truth for yourself? Tune in to the brand-new show made even more accessible to the Indian audiences on Channel K.
