100 akorns to who can guess my pick for "Best Girl Group Comeback of all Time"

You can guess as many times as you want. But please limit to one guess per post.

This isn't necessarily my favorite girl group comeback of all time but it's what I consider to be based on song quality, concept, visuals, MV, and just the closest any group could ever get to being "Perfect".

Only hint is its NOT an f(x) comeback.

Good luck to all participants.

Yall? I need the group AND the song.

f/x

Why is this still so hard for yall to understand? What part exactly are we struggling with here?

I said its not f(x). And I need the song to go along with the group.

I'm still mad though lol. This was supposed to go on for at least 2 days. You must have remembered me saying this before about Heart Attack.

Quote from Whi

nah idt you’ve out right mentioned heart attack anywhere, but i know you like aoa and based on your taste plus the actual songs’ quality heart attack just seemed to be the most logical answer and voila i was right

That's incredible detective skills.

If anyone is curious #2 is SNSD Genie.
