ChoA has dropped her music video for "Yesterday".

In the MV, ChoA slowly falls asleep and wakes up in a dream that makes everything look different. "Yesterday" is an acoustic ballad track about wanting to return to the past when you were with someone you can't forget, and it's the former AOA member's first official release since returning from her hiatus.
