Various photos have been dropped for the members over the past couple of days, and the new batch today gives us a look at the dark version teasers for Hyosung and Hana in addition to the previously revealed dark versions for the other two members Ji Eun and Sunhwa. 

Anticipation is high for their comeback, especially because this is the group's first time working with Duble Sidekick for their title track "I'm In Love".
