UPDATE: hard-subbed one is now available
Not only Japanese eels but eels over the world witnessed this precious and memorable moment on the internet. I subtitled this video for international eels who are supporting Jang Keun Suk to be World Prince as well as Japanese eels. Jang Keun Suk is already loved by eels throughout the world! Prince, ZIKZIN to the world!
