according to the internet, I have the Hong Kong version
the release number is SMJTCD159
though it says it's released from both avex trax and SM entertainment, who I know are mostly associated with k-pop groups, it does have the SM hologram which I think is proof it's the real deal, but still seems a bit odd, shouldn't avex trax asia have released it?
also...the song 'until that Day...' has a very sudden cut-off ending, I've looked on youtube and this seems to be the case for the song all the time, is it same with yours guys?
