I think I have an idea of a story for you write. Ever thought of writing a mermaid version of Transformers? Your OCs will no doubt be involved as usual, and that it will be interesting to see. But I can't exactly think of an idea of the plot except for a human falling in love with a sea creature. Let me know of what you think of that idea. You don't have to do it and you can take as much time if needed.
