ZE:A drops surprise BTS video of 'Step by Step'

On October 4th, ZE:A dropped a surprised video on their official YouTube channel.

They released the BTS video of their song 'Step by Step,' which was part of their 'Illusion' album in 2013. The video was named 2014 Happy ZE:A’s Day on the "1004 Day." The reason behind their surprise is that the numerals 1004 (October 4) and 'angel' (천사) have the same spelling and pronunciation.
