Solo singer IU released the official MV teaser of her upcoming hit song Good Day!

I have no idea whether her new hit song is a ballad or pop song,but i prefer to see her with some cute dance steps on the stage,showing more energetic side of this 17 years old girl.

By the way,the parrot in the MV teaser reminded me of KARA's Wanna,kindly take a look at the MV below!
