MAMAMOO+, a subunit of the group MAMAMOO made up of Solar and Moon Byul, are back with their 1st single album, "ACT 1, SCENE 1," and the title track, "Good Girl, Bad Boy, " much to the delight of fans. The subunit made sure to release a guide to their moomoos in regards to how to cheer for the title track, several hours after the MV was released. So that fans can get into that comeback spirit. 

Much to the delight of fans, the cheering guide is just as energetic and colorful as the title track. Allowing the idols and fans alike to show off their goofy energetic side while cheering during the girl's performances. 

The song also sounds like an absolute dance bop, perfect for a sugar rush in the spring! It's nice to see the girls so excited and cheerful, as proven in the "GGBB" dance challenge choreography video posted so that the fans can dance to the song as well.
