K-Drama S Line Sparks Viral Red-Line Meme Craze



Evanne Evans, 20 Jul 2025

Korean dramas are no strangers to setting social media on fire, but the latest phenomenon comes from the new psychological thriller S Line. The show, starring Lee Soo-hyuk, has ignited a viral trend with its now-famous red line visual, a glowing connection seen floating above characters' heads, symbolizing their past romantic entanglements.

In S Line, Lee Soo-hyuk plays a man who mysteriously gains the ability to see these red lines. But here’s the twist: not everyone can see them, and the lines don’t necessarily lead to happy endings. Instead, they expose complicated romantic histories, secret affairs, and emotional baggage, turning love into something visible and, at times, unsettling.

Fans quickly latched onto the imagery, turning screenshots into memes across platforms like TikTok, X, and Instagram. Some have humorously edited the glowing red lines onto photos of celebrities, ex-partners, or even themselves, imagining what their own romantic networks might look like if life were to mirror the show.

According to outlets like India Times and Soompi, the trend has sparked deeper discussions. Viewers are debating whether they’d want the power to see such connections in real life. Would it lead to greater honesty, or just more heartache?

The meme’s popularity has also drawn attention to S Line's broader themes, which go beyond the supernatural element, as the show explores emotional vulnerability, trust, and the invisible ties that linger long after relationships end.

With its blend of sleek storytelling and social commentary, S Line has managed to achieve what many dramas aspire towards, to captivate audiences and spark global conversation.
