Ok, there is nothing really “secret” about this, but rather the Korean girl group involved is call Secret. I know, I have posted their videos at Blade & Soul’s Soul Party 2 previously over here. But hey, this new video contains official live footage of the event and it is from NCsoft. and I can’t get enough of the song + music video 
The earlier part of the video actually talks about designing dresses for the Secret girls based on in-game designs. Awesome eh? Closed Beta 3 is currently ongoing for selected users, with the official CBT 3 phase beginning tomorrow iirc, also for selected users.
