It turns out, the mysterious new Instagram the label opened a month ago belongs to this new unit! Called Y-Teen, it consists of all 7 of the MONSTA X members, and Cosmic Girls's Exy, Cheng Xiao, SeolA, Soobin, Eunseo, Yeoreum, and Dayoung, for a total of 14 members!

Y-Teen's main purpose is to act as the brand models for KT's phone fare service, also called 'Y-Teen'. The unit group will be promoting the phone fare service through a variety of activities and promotions, including music releases, MVs, and more!

Y-Teen will begin promoting toward the beginning of August, after releasing a single and a MV. If you haven't started following their Instagram already, you can find it here. 

Stay tuned for more from Y-Teen!
