BTS’ Jin and BLACKPINK’s Jisoo have become the latest subjects of playful fan speculation, all thanks to a viral TikTok video that sparked a wave of imaginary dating theories. The buzz originated not from any direct interaction between the two idols, but from a coincidental fashion choice. Both were seen wearing similarly styled plaid shirts around the same time, which was all it took for fans to let their imaginations run wild. Given Jin and Jisoo’s status as some of the most visually iconic figures in K-pop, the idea of pairing them up—even jokingly—quickly caught on.
Jin, currently on his solo RUNSEOKJIN\_EP. TOUR, appeared on stage wearing a relaxed, countryside-inspired outfit featuring a checkered shirt and a straw hat. Meanwhile, Jisoo posted a series of photos from BLACKPINK’s ongoing DEADLINE world tour, one of which showed her in a similarly patterned checked shirt, worn off-stage in a casual setting. Though the prints weren’t identical, the overall vibe was close enough to spark attention. A fan compiled the visuals into a side-by-side TikTok clip, which rapidly went viral.
The video was meant to be humorous, captioned with exaggerated claims about the pair’s “matching couple looks” and a flood of light-hearted comments. Viewers jumped in with mock detective work, laughing over how quickly a shared fashion style could escalate into imaginary romance theories. One fan jokingly called for fellow “delulus” to rise, referencing the K-pop fandom slang for fans who knowingly indulge in far-fetched fantasies. Others tagged friends, declaring the two idols a perfect visual match, while some laughed at how little it actually takes to start a fake dating narrative in fandom culture.
It’s important to note that these reactions are meant to be fun and not taken seriously. There is no romantic connection between Jin and Jisoo. The trend is an example of fans engaging with idols in creative, humorous ways, fully aware that the scenarios are fictional. Many comments on the video even acknowledged how “delulu” the whole thing was, with fans lovingly poking fun at their own imaginations. In the world of K-pop fandoms, moments like these are part of the shared joy and collective amusement that keep fan communities vibrant and engaged—even if it all starts with something as simple as a plaid shirt.
