The two films are just the original cast, and the actors have not changed anything, but the plots are completely different, and they are not sequels, but two completely different dramas. It's just that the actors haven't changed anything, so they are all called "The Heart of Greed", but the first one is "The Heart of Greed" and the second one is "The House of the Storm", full moon. The plot is completely different, and the characters have changed a little.
