Okay okay I admit (-_-) I've been the lazy one here for not uploading this. They released the Japanese version a long time ago but I haven't seen SM upload this yet so I had to search for it.
I can easily say that I prefer the Korean version more, sure there's a lot of good Japanese versions out there but the Korean a.k.a the real version is usually the best one.

But the end was just EPIC! Shindong and Sungmin coming out of nowhere XD
