Upper Room has issued an official apology after photos showed Mark wearing a T-shirt featuring the Confederate flag, a symbol widely criticized for its historical links to racism. The Mark apology came after the images circulated through online communities and social media, prompting criticism over the clothing choice and its public exposure.1
The agency said the item was selected as a vintage T-shirt but acknowledged that it should have recognized the historical meaning and sensitivity of the symbol before the photos were shared. Reports said the images were later deleted after the controversy developed.1
Mark Confederate Flag T-Shirt Photos Draw Criticism

The controversy began after photos of Mark wearing the Confederate flag T-shirt appeared online. Xportsnews reported that Upper Room, Mark’s one-person agency, posted an English-language apology through an official account on June 23, 2026, after the images drew concern and criticism.1
The Confederate flag has long been associated with the Confederacy during the American Civil War and with slavery, making its use in fashion and entertainment especially sensitive in international contexts. Hindustan Times described the backlash as tied to that historical background, while Korean outlets framed the symbol as one connected to racism.2
Upper Room said the clothing had been chosen simply because it was vintage. JoongAng Ilbo reported that the agency explained the item was not intended to appear in official content, but that the image was nevertheless shared externally.3
The agency’s statement included a direct apology to those affected by the images. Upper Room said it “sincerely apologizes for causing concern, discomfort, and disappointment” over the vintage T-shirt seen in the recently released photos.1
Upper Room Says It Takes Full Responsibility
In its official response, Upper Room said it recognized the issue only after the photos were seen publicly and criticism followed. The agency said it had not properly understood the historical meaning and sensitivity of the symbol at the time the clothing was selected.1
OSEN reported that the agency said the matter should have been handled with greater care and that it accepted responsibility for the mistake. Upper Room also said it would strengthen procedures for selecting outfits and reviewing content to prevent similar incidents.4
A separate part of the statement emphasized accountability. Upper Room said it “fully recognizes responsibility for this mistake,” according to OSEN’s report on the official statement.4
The agency’s explanation has remained focused on the styling process, the vintage nature of the clothing, and the failure to identify the symbol’s meaning before the photos were shared. No additional schedule change, disciplinary measure, or separate statement from Mark himself was included in the provided reports.
Several outlets reported the apology as coming from Upper Room rather than as an independent personal statement from Mark. Soompi reported on June 23, 2026, that Mark came under fire after the newly established label posted photos of him wearing the T-shirt, and that Upper Room apologized afterward.5
Background On Mark’s Current Agency Status
The controversy comes during a period of transition in Mark’s career. JoongAng Ilbo reported that Mark left NCT after the end of his contract with SM Entertainment in April 2026 and has since been active through his personal agency.3
Star News also reported that Mark parted ways with SM Entertainment in April 2026 and established Upper Room earlier in June 2026.6 Soompi similarly reported that he left both NCT and SM Entertainment in April and announced Upper Room earlier in June.5
That timing made the agency’s response central to the public handling of the issue. The available reports describe Upper Room as the party that posted the apology, explained how the clothing was selected, and promised stronger checks for future content.4
The reports do not provide details about where the T-shirt was obtained, who selected it, or whether the photos were part of a specific official project. The confirmed facts are limited to the appearance of the images, the criticism that followed, the deletion of the photos, and Upper Room’s public apology.

Upper Room’s apology addressed the immediate controversy by acknowledging the harm caused, explaining that the T-shirt had been selected as a vintage item, and promising stronger review procedures. The issue now stands as a public content and styling controversy centered on the Confederate flag T-shirt photos and the agency’s response.
