Thanks for the reply.
I tried to do what you are saying in the past, but when I saved to the copied file, it would overwrite the original save data, so I was wondering if there is anything I can do.
I guess it is something internal to the program as it seems to be reflected in the data in %appdata%/renpy /lustfuldesire... as Itsara mentioned.
I don't want to break a nice game so I will take care of it myself and play it.
Thank you very much.
