On September 9, 2025, outrage spread across social media after a video involving HYBE’s rookie boy group CORTIS went viral. The clip reportedly showed fans attempting to film the members while they were changing backstage, raising concerns about privacy and safety.The video, which surfaced on X, appeared to capture people filming through gaps in a backstage tent. In the footage, Martin, the group’s 17-year-old leader, seemed to notice what was happening and quickly moved away. Many online condemned the incident as invasive.Fans expressed that such behaviour was unacceptable, especially since four of the five members are underage. The incident comes less than a month after CORTIS debuted with their singles, Go!, What You Want and their EP Color Outside the Lines.Reportedly, just days earlier, the group was criticized online for using multiple umbrellas to shield the members backstage. At the time, some netizens called it "excessive." However, the latest incident led many to argue that such precautions were clearly necessary to protect the boys' privacy.Fans slammed the perpetrators and called out their behavior.

The group name CORTIS is an acronym that stands for "Color Outside the Lines." The name represents individuality and creativity, with all members partaking in songwriting, choreography, and production.Despite being new, the group has already gained attention for its talent. It has also received support from BTS' Jungkook and j-hope, who publicly endorsed their pre-debut track GO!.jade ✮ @218ACEHSKLINKno wonder j-hope gave an advice to cortis and even did a dance cover of their song, ace knows real talent. love how they are involved in creating their own music unlike a lot of newly debut groups nowTheir debut, however, has been shadowed by sasaeng (overzealous fan) activity. The viral clip of fans filming them while changing is the most extreme case yet. However, earlier incidents showed fans chasing the boys in public spaces. These situations have reignited debates about idol protection, especially for teenage groups.CORTIS’ popularity is rising steadily. Their latest EP includes tracks like Fashion, Joyride, and Lullaby. Fans are now urging BIGHIT Music to step in with stronger measures to ensure the safety of its youngest idols.As of now, the company has not issued an official statement about the viral video.
