About an hour ago, @FNC_Ent tweeted about a surprise teaser on their website that will be released at 12 pm KST. Minutes after that they tweeted again that it's about  "an artist behind FT Island's comback" 

And finally the teaser is up! It's just 18 seconds teaser with a white shaking background with the written. The video's tittle is "INST (흔들려)"

흔들려 

MV Release 2013.10.10

ON,OFFLINE Release 2013.10.14

At 12pm the url is  http://fncent.com/teaser/aoa/0930_inst.html

AAfter a few minutes they changed it into http://www.fncent.com/teaser/inst/0930_inst.html

It supposed to be a surprise like FNC's tweet stated. But I think there's some technical problem. So, yeah... let's say it it's leaked. kkk~ Now everyone know, that that blurry 18 seconds teaser is AOA's.

The title itself is 흔들려. It's literally means shaking or blur. So, it's the concept of the teaser. Shake, blur, and u supposed not to know until the time has come! 

Congratulation AOA! Welcome back to the stage!

*Note: The very possible is AOA. Because actually AOA has been planned to comeback on Sept 6th. But, because many preparation haven't done (AOA Black just bid a goodbye stage last month) and FTISLAND's special comeback, FNC postponed their comeback. So it makes sense if it's AOA's comeback on 2012.10.10.

If any of u have heard about CNBLUE's preparing their comeback. Maybe it's right. But, it's near impossible to make FTISLAND and CNBLUE in the same promotion time. 

PLESE GIVE UR LOVE AND SUPPORT TO FNC'S ANGELS! THANK YOU!
