After the hilarious teaser with Jung Hyung Don a couple days ago and Gayoon's yesterday, 4minute's sub-unit�2YOON has unveiled a another MV teaser this time featuring Jiyoon!

This is for the music video of the girls' title track "24/7", which is described to be a country pop dance track off their upcoming album 'Harvest Moon'.
