Astro is a kpop boy band, that debuted in February 23, 2016 with their mini album 'Spring Up'.
They had already went public before that date. They had there own reality show called 'Astro Okay, Ready' in January 2016, and before that they were leads in the drama called 'To be Continued" in August 2015. I watched both the reality show and the drama, and I was already excited about this boy group before they I even heard there music. I have watched most of there V live broadcasts (they are really fun), and most of us that watched 'Unpretty Rapstars' season 2 knew a little bit more about MoonBin, because of his sister Sua which was a contestant that year and went to the finales.
This is him with his mother at the finales to support his sister.
