I'm really enjoying this! I was hoping for a sexy concept, but I like this mature concept a lot more. I was getting tired of the same cute concept over and over again, its refreshing to see this. They all get to show how beautiful they all are, instead of making cute/funny faces and bouncing around all over the place. Hyeri looks especially good in this video, she had my heart fluttering near the end~ I hope to see more of this mature Girl's Day after this~
