The Korean show The Immortal Lee Soon Shin - who is his friend?

I saw some Asian soap operas a while ago like the Empress Wu which as dubbed into English with a cod Chinese accent. There are others, most of the, are invariably based on historical characters one that I saw recently was the Immortal Leen Soon Shin however the DVD's had 33 episodes out of 104 episodes. Apart from the fact that all the Japanese "baddies" bald patches are rubber and are not on properly and all appear to be popping a vein when they go "arrghh foiled by Lee Soon Shin again" in a melodramatic way, then have a hissy fit and execute some people for failure or not getting out of the way quickly enough.The greatest mystery is who is the guy who is hanging around with Lee Soon Shin? The little guy with long hair that stick and extremely good fighting skills and I suspect he is either his friend / servant but I have no idea what his name is in all the episodes he is always there yet I never found out what his name was. I tried to find out but as I don't know what the character was called it is a problem.Also has the actor who played Lee Soon Shin been in any films as he is a really good actor.
