Sorry for the late response, yokoso but...
MUCH THANKS FOR THE LINK!!!!
Strangely, I had visited Cori's page when the song was first released but at that time there was only the original translation. I never thought about going back there to re-check the page

Of course, Tommy heavenly6 had abit of an edge... It's her video
