As the girls get closer to their comeback, they recently released a highlight medley for their 5th mini-album 'The Blue'. Now, they dropped an "MV reaction" video of their own for "The Blue Bird", which is the title track. 

In the beginning, the members pointed out that this is the very first time they are watching the fully-edited video and gave their honest reactions.

'The Blue' is set to drop on March 12 KST. Are you excited for April's comeback?
