Girl's Day have always been the epitome of 'cute', but with "Expectation", they put forth a sexy image instead.

The girls were asked to rank each other on sexiness, and leader Sojin ranked #1, while maknae Hyeri ranked last. When the girls picked Sojin, they reasoned, "Starting from when we practiced, she had a sexiness that the other members couldn't follow. She is the best at expressing controlled sexiness that's not too much or too little. In our team, she's a wall we can't go over."

On Yura, the girls said, "As everyone knows, her body is the best. She also has eyes that you see on the best sexy stars like Kim Wan Sun sunbaenim. Yura's trademark black eyes are so charming. Her eyes make your heart beat. We think she'll be the most distinguished through this promotion."

Minah was ranked 3rd because, "To be honest, our ranking is all the same. Anyway, Minah matches really well with sexiness. She's good with sexy facial expressions or with transformations, but the public's image of the cute, bright Minah is so strong, so we picked her 3rd. If you look just at this stage without previous opinions, she's really sexy. So you really have to see the stage."

Hyeri was picked last by herself. She explained, "I don't want to be chosen as 4th, so I'll make myself 4th. To be honest, it was hard for me to make a sexy face or gaze because it was my first time. But since it's so hard, I just try to do my best instead of trying too hard to be sexy".
