+ Hyun Ah (현아) (4 Minute 포미닛)
& UEE (유이) (After School 애프터스쿨)
HyunAh & UEE are not singing, only featured in the music video.
Baah, I'm not fond of Hyunah's voice but she's super cute in the MV! I was hoping UEE would do something... interesting, but I guess it's okay. But it's another catchy Mighty Mouth song~
