Do you have a source for the performers? The only one I found is Wikipedia and it just mentions a few of them:

Nevermind, found one:

I'm not familiar at all with the franchise so if anyone is, feel free to fill in the character names.
The site also has info about the Shin drama series by pony canyon, so be sure to take a look if you want to submit them
