Fans claim that there is a strong possibility that MAMAMOO's Moonbyul has begun or already undergone a hair transformation for the group's upcoming comeback. In the Instagram posts from her fellow "Top Girl" soccer team members, the singer is seen holding a teammate's baby, who is cutely referred to as the unofficial mascot. Many fans gushed over the cuteness overload in the picture, while others were quick to point out the difference in the idol's hair color.

Many fans pointed out the fact that instead of black hair, the singer now dons a light ashy hair color. Reminiscent of when the singer went with an ash grey color for MAMAMOO's "Decalcomanie" (2016) music video. An era that is known by the group's fandom for being one of MAMAMOO's most iconic comebacks from the styling to the performances.

Although nothing is confirmed for sure, and a few fans did point out that this photo may have been taken during Moonbyu's "C.I.T.T (Cheese in the Trap)" (2022), others were quick to point out the difference in tone and shade of blond. Either way, many fans are excited about the possible return of the ashy grey-haired MoonByul this comeback, and since the singer is participating in the singing competition for "JTBC's "Second World." A weekly Korean completion show, the wait may soon be over for many impatient fans.
