Nice! That makes a lot of us now having fanaccounts of the DKFC! I have one too (LOL, shameless plug).
I know how you feel. I myself waited two years before I finally saw them in person last year in Bangkok for their solo concert - 2nd Asia Tour. The thing is, I thought for a while there that finally seeing them live and alive would probably be the peak of my being a fan. How wrong I was. Seeing them in person in Bangkok just made me want to see them more and more. I saw them again four months later in SMTOWN Taiwan. And the feeling was still there. The more I saw them, the more I wanted to see them more and more (again, shameless plug - if you have time, maybe my fanaccounts in these two concerts would help explain more what I was going through).
It's been over a week already, and yeah, I still have withdrawal syndrome. My throat still hurts until now. I know how you feel. Heck, it's been almost a year since Bangkok for me and still I remember every single bit like it was just a couple of hours ago. I dunno why, I dunno how, but yeah, SNSD has that power over me.
Anyways, congrats on finally seeing them in person, and here's to hoping for another opportunity sometime in the future! Cheers!
