Billlie’s AI-Plagiarism Controversy Just Made '$ECRET NO MORE' Bigger Than the Comeback Teaser

Billlie (빌리) is heading into its May 6 comeback with a far messier storyline than Mystic Story likely wanted. After the group released the animated cartography of the unconscious film for B-side “$ECRET NO MORE,” fans and the creators of the French short film Niccolò accused the teaser of leaning on generative AI and borrowing too heavily from another work, according to Soompi’s April 25 report and the Niccolò creators’ own social posts quoted in that report. Mystic Story later said it reviewed the film and found no intentional appropriation or copyright violation, while also promising greater caution around AI use going forward, as reported by Soompi. That matters more than one pre-release clip because Billlie was supposed to be building clean momentum for its first full album, the collective soul and unconscious: chapter two, due May 6 at 6 p.m. KST per Mystic Story’s teaser rollout and our earlier coverage of the comeback schedule.

Why the “$ECRET NO MORE” backlash hit harder than a normal teaser complaint

The backlash became a real comeback problem once the conversation moved from whether the teaser looked unusual to whether it crossed an authorship line. According to Soompi, fans first flagged the film’s stylized animation as possible generative AI before the creators of Niccolò, a 2025 French student short, publicly said on social media that their work had been used without permission or credit. That is the point where this stopped feeling like routine stan outrage and started looking like a credibility issue around process, originality, and respect for artists outside K-pop’s own system. We have seen teaser debates come and go, but allegations about how a label built a visual are different. They stick because they hit the exact thing fans want from a concept-heavy group like Billlie: intention, authorship, and a world that feels handmade instead of machine-assisted.

Mystic Story’s response tried to close the issue, not erase it

Mystic Story’s current position is clear on paper, even if it has not fully cooled the room. According to Soompi, the company said the film was created as an original work and that its internal review found no intentional appropriation and no copyright violation. allkpop separately reported that CEO Jungsu Han had first defended the possibility of AI as an artistic tool before later apologizing and promising there would be no unnecessary AI use in work connected to Billlie or Mystic Story artists. That shift is the real story inside the statement cycle. It tells you the label understood the fan pushback was not just about optics. It was about trust. When a group trades on lore, atmosphere, and visual authorship, the audience expects every part of the rollout to feel deliberate. Once that trust gets dented, even a polished apology reads less like closure and more like damage control before release week.

Billlie’s May comeback now has a sharper stakes question

Billlie’s album is still scheduled for May 6 at 6 p.m. KST, according to Korean coverage from StarNews and allkpop’s teaser updates, so the release itself is not the uncertain part. The bigger question is whether the music can outrun the rollout discourse fast enough to reset the mood. That is possible. K-pop fans will absolutely lock back in if the songs hit. But this controversy changed the frame from “Billlie is finally back with its first full album” to “can Billlie and Mystic Story restore confidence before the album lands?” That is a much tougher headline to wear in comeback week.

There is also a broader industry angle here. Billlie has always sold a carefully built universe, and that is exactly why this story traveled beyond the group’s own fandom. When labels flirt with AI-adjacent visuals, they are not only making a production choice. They are testing how much ambiguity fans will tolerate around authorship. The wider K-pop commentary ecosystem, including outlets and podcasts such as The Kpopcast, keeps rewarding acts that feel specific, intentional, and human in their creative identity. That is why this moment matters. If Billlie’s full album delivers, the group can still turn the conversation back toward music. If it does not, this teaser controversy becomes the story people remember first.
