Transmigration: I'm a Mother Of a Mermaid

The world is constantly developing, innovating into a better future for the better. But for some people this innovation can become destruction, and I was one of these people who suffered for the betterment of the people whom I didn't even know. My accidental death didn't took me to hell nor heaven, I went to another world instead. The world which was completely different from my original world, cause there existed mythical creatures like mermaids. But the bigger issue here was that I transmigrated in the world of a novel, that was written by my favorite author. The book about the Mermaid Princess and a human man, but this story was nowhere like our usual bed time story. This was the altered version, with darkness, mystery and suffering of this two people. I had no idea what role I was playing, but I was more concerned about the sudden child in my stomach that was gifted to me from no idea where. Gotta find the father of my child~
