HIGH4 get ready to drop sub-unit called... HIGH4:20

Yup, you read that right.  They pretty much covered all the bases with that name.

HIGH4 members Alex and Youngjun will be coming together to create HIGH4:20, which will release song "Hook-ga" on October 3.  They dropped a teaser image of the two members wearing matching jackets with their names on the back as they point at each other.  Looks like it'll be an edgy release!
