ASTRO's Moonbin and Sanha have dropped their music video teaser for "Bad Idea".

In the MV teaser, Moonbin and Sanha fall into a nightmare of broken glass, shadows, and rain. Sanha and Moonbin are grouping together as ASTRO's first unit, and their mini album 'IN-OUT' and title song "Bad Idea" drop on September 14 KST.
