When a sea witch mermaid hides her baby to lure some human fisherman away, she returns to find her baby gone and being carried away by humans who found the human-looking baby and assumed it was abandoned. The baby grows up into Person A, who continually has prophetic dreams, some sent by their mother into their mind and some due to their own witch powers, which keeps them out of trouble for the most part. But Person A’s other parent was a siren, and so Person A has a knack for singing, and is nicknamed ‘Mermaid’ by their friends due to their skills in swimming and singing. One day, their out singing on the beach, when they hear a responding voice. Person B, the owner of the voice, is a mermaid outcast, looking for their soul mate, who just happens to be Person A, and when they realize their soul mate’s song is coming from land, go to a sea witch to become human temporarily in order to track down and meet their soul mate, who they assume must be trapped by humans.
