Girl's Day was really so pretty when they were promoting the song "Darling."

Actually, well, all the promotional songs were like that, but...

I think this song was especially like that.

The song suited it well, too.

All four members really suit pink so well..

Just like the top commenter on YouTube said, they really were human Etudes lol

I'm getting lost in memories while listening to this song for the first time in a long while.
