Intro

It is thanks to the mermaid that I am alive, but this same mermaid refuses to let me return to the surface. Instead, she watches me with eyes that seem to be admiring a newly acquired treasure.

The mermaid, who holds the key to my escape, seems to have no intention of considering human circumstances.

Creator Comment

This is a plot designed to see the difference between a female mermaid version and a male mermaid version within the same world setting. That aside, non-human entities that don't speak human languages are great, aren't they?
