ASTRO is gearing up for their comeback with teaser videos for each member!

The group began the release of individual 'concept films' on January 8, starting with ASTRO's youngest member Sanha. In the clip, he appears particularly pensive, staring aimlessly at a goldfish as it flits around in a glass of water. With pale purple hair and dark green eyes, he boasts some striking visuals, ending the video by staring confidently into the camera.

Meanwhile, ASTRO's first full-length album 'All Light' is set for release on January 16.

Stay tuned for more concept films, and check out Sanha's above!
