Hongjoong of the group ATEEZ showcased his presence with a self-composed song. On December 27, Hongjoong released the video for his solo track "NO1" on ATEEZ's official YouTube channel. The released video harmonized warm colors with a game-like mood, emphasizing Hongjoong's trendy sensibility. The dynamic choreography unfolding over a rhythmic beat perfectly matched the atmosphere of the song. Hongjoong's visuals, witty subtitles appearing at just the right moments, and unique effects added fun for the viewers.

"NO1" is a solo track included in ATEEZ's 12th mini album, "GOLDEN HOUR: Part.3 'In Your Fantasy Edition'." The song conveys the meaning that "on this stage right now, I am the only No.1, and no one can be like me." The intense chorus and sound of the club house and EDM genres combine with a confident message to create a strong addictive quality.

Through ATEEZ's 2025 world tour "IN YOUR FANTASY," Hongjoong delivered a stylish performance holding a DJ box on his solo stage. In each city, he exploded the audience's adrenaline with powerful rapping and unrestrained energy through different productions. Hongjoong has steadily participated in album production as a member of ATEEZ, building his musical foundation. In his solo track "NO1," he demonstrated his lyric-writing and composing skills, firmly establishing his identity as an "all-rounder artist."

As expectations for Hongjoong's diverse musical spectrum grow, ATEEZ is set to appear on the "2025 MBC Gayo Daejejeon Mutt" broadcast at 8:50 PM on the 31st, marking the pinnacle of the year-end stage. Through this performance, ATEEZ plans to strengthen communication with fans and further solidify the group's presence.
