The year 2025 has already proven to be one of the most explosive eras in the history of Hallyu. As the global stage prepares for the monumental return of the “Kings of Pop,” the atmosphere surrounding BTS’s upcoming Seoul comeback concert has reached a fever pitch. However, amidst the technical preparations and high-octane choreography, a single frame from a behind-the-scenes practice video has sent shockwaves through the industry. The center of this storm? A long-standing rumor involving BTS’s “Golden Maknae,” Jungkook, and aespa’s ethereal visual, Winter. For months, fans have whispered about the possibility of “WinKook,” but a new video has provided what many are calling the ultimate “confirmation” of their alleged couple tattoo.
K-pop fans are no strangers to the “detective” culture that permeates social media. When a high-profile idol is involved, no detail is too small to be analyzed. The dating rumors between Jungkook and Winter didn’t appear out of thin air; they have been building momentum throughout 2025 like a slow-burning fire. It began with “coordinated” fashion choices—pieces of clothing that appeared in separate schedules but shared uncanny similarities in brand and timing. Then came the accessories: rings and necklaces that seemed to mirror one another.
The speculation took a more intimate turn when fans noticed both idols sporting purple nail polish on their ring fingers at different times—a color deeply symbolic within the BTS ARMY and a finger traditionally associated with commitment. But even with these clues, the public remained divided. That was until the “Three Puppies” entered the conversation.

The most damning piece of evidence, according to netizens, is a specific tattoo design: three small dogs lined up in a row. For a while, blurry photos and low-resolution fan-taken shots suggested that both Jungkook and Winter had acquired this specific ink in almost identical locations—just above the elbow.
Lmao where are the Jungkook stans that are still in denial? Jungkook still has the couple tattoo with Winter 😭😭

In the world of K-pop, tattoos are deeply personal and often permanent markers of one’s journey or relationships. To have a matching design in a matching, relatively hidden spot is considered by many as a “loud” statement made in silence. For months, the “Puppy Tattoo” was a myth—a theory debated in the dark corners of X (formerly Twitter) and TikTok. That is, until the latest BTS practice session video went viral.
As BTS rehearsed for their massive Seoul comeback, cameras captured the members in their most raw and hardworking state. The video, intended to showcase the group’s dedication and the scale of their upcoming show, inadvertently became a focal point for relationship theorists.

During the rehearsal of the concert’s closing bow—a moment of gratitude where the idols raise their arms in unison—Jungkook’s sleeve shifted. For a split second, the area above his elbow was exposed to the light. Eagle-eyed fans immediately froze the frame, zoomed in, and enhanced the resolution. What they saw was unmistakable: the same three-puppy tattoo that had been linked to Winter.
The footage spread like wildfire. On platforms like Weibo and Instagram, side-by-side comparisons of Jungkook’s arm and previous glimpses of Winter’s alleged ink garnered millions of views within hours. The narrative shifted from “coincidence” to “confirmation” in the eyes of many supporters.
In the high-stakes world of K-pop PR, silence is often a strategic choice. As of now, BigHit Music (HYBE) and SM Entertainment have maintained a strict “no comment” policy regarding the dating allegations. In an industry where agencies are usually quick to deny baseless rumors to protect their artists’ commercial viability, this prolonged silence has only added fuel to the fire.
Jungkook and Winter themselves have remained characteristically quiet. They have continued their professional schedules with poise, neither confirming nor denying the whispers. This lack of a direct address has led to a fascinating divide in the fandom. One side sees the tattoo as a brave, subtle way for the two idols to share their bond with fans without inviting the chaos of an official press release. The other side remains skeptical, arguing that the designs could be temporary, different, or simply a popular trend among tattoo enthusiasts in Seoul.
Regardless of the truth, the “WinKook” phenomenon represents a shift in how modern K-pop fans interact with their idols. The focus on the “Three-Puppy Tattoo” highlights a desire for authenticity and human connection behind the polished image of a global superstar.
As BTS prepares to take the stage for their Seoul concert, all eyes will not only be on their vocal performances and choreography but also on every movement of Jungkook’s arms. Fans are waiting to see if he will choose to cover the ink or wear it proudly. Similarly, every appearance by aespa’s Winter will be scrutinized for a matching glimpse.
The latest video has undoubtedly restarted the conversation, pushing it into the mainstream media’s spotlight. Whether it is a coincidence of artistic taste or a genuine symbol of a secret romance, the “Three-Puppy Tattoo” has become a part of K-pop lore in 2025.
For now, the rumors remain “alleged,” and the tattoos remain a mystery shrouded in practice room shadows and stage lights. But in the world of BTS and aespa, where the fans see everything, a secret this “inked” might not stay hidden for long. The story has started again, and the world is watching, waiting for the next clue in what might be the biggest K-pop romance of the decade.
