New sub-unit HIGH4:20 tease for debut with featured artist

HIGH4's new sub-unit, HIGH4:20, consisting of Alex and Youngjun, dropped their first teaser video for their debut.

The teaser is simple and dark, with both members dressed in casual street attire and looking either at each other or over their shoulders as if running away from something. The song is titled "HookGA" and will feature an artist, whose name has yet to be revealed!

Excited?
