Will anything come after The Great Mystery?

• I heard that The Great Mystery producers hinted that there might be more to come. What can we expect from the follow-up, and do you think a follow-up can be successful?
• Hi! I heard exactly the same thing. To tell you the truth, I don't expect much of it. I think nothing can be as good as the first movie, but I like the main character so much that I will see the follow-up for sure.
