Since Girl's Day has a lot of followers, I know that this post is really late from the time the teasers and the MV of Hello Bubble has been released. But of course, YURA is my bias [coming from watching her via WGM] so I might as well make my own gif and screen caps version of the MV and making film.
This is YURA Cut with Hello Bubble.
