ASTRO's Moonbin and Sanha have dropped their dance practice video for "Who".

In the dance practice video, Moonbin and Sanha dress in all black as they go over the choreography with their dancers. "Who" is the title song of their second unit mini album 'Refuge', and the lyrics are about running away from a shadow chasing you.
