Jooheon premiered the stage of the title track "STING (Feat. Muhammad Ali)" from his second mini album "光 (INSANITY)" on Mnet's "M Countdown" broadcasted on January 15. Through this performance, Jooheon showcased his unique presence.

In the comeback interview, Jooheon demonstrated his skilled wit as a former "M Countdown" MC, leading the atmosphere on site. He introduced himself as the "20s Prince" of "M Countdown" in line with the broadcast concept and drew great cheers from fans with his signature aegyo "Kkukku Kkakka." Regarding the new song "STING," Jooheon explained, "It is a song inspired by Muhammad Ali's phrase, 'Float like a butterfly, sting like a bee,'" expressing his ambition by saying, "I will shoot rap into your ears."

On stage, alongside special MCs Kang Daniel and ZEROBASEONE Park Geon-wook, he presented the "STING" challenge, exuding intense charisma. As the main stage began, Jooheon appeared wearing a striking red hood and pants setup, commanding attention. Against a background reminiscent of a boxing ring, he delivered a powerful performance, perfectly controlling tempo with choreography incorporating actual boxing techniques such as "weaving" and "swaying."

Jooheon's stage presence was explosive. The cheers from Monbebe, who attended the venue, further heated up the stage. Having served as an "M Countdown" MC in 2023 and gifted Monbebe with a special stage before his enlistment, Jooheon responded to fans' passionate support on this solo comeback stage with sharp rapping and live skills.

Jooheon announced a successful comeback with a catchy melody and relaxed stage manner. He will continue promoting the new song "STING" by appearing on KBS 2TV's "Music Bank," which airs on January 16 at 5:25 PM. Attention is focused on Jooheon's next stage.
