Hi Carlos!
It has been a real pleasure reading this story. The way you have narrated an event and then narrated what lead to it, makes the story more interesting. The description of all the sight seeing, the dives & discovery of the sunk ship with the treasure; exhilarating! Jay being the nutcase arouses passions. I'd love to beat him up. Poor guy!
You have given hints on what is to come, good! What about the Tokyo trip? I'm sure exciting things will happen there too! Don't deprive us of that if you can help it & fit it in.
Lastly! I'm sad on this having ended as I've thoroughly enjoyed it. I really don't know. This seemed to me a bit different!
