I came up with this AU about my OC Khayn during Mermay and only now I managed to finish this (chemotherapy got in the way). In this AU, he’s a lonely mute merman that fell in love with a human girl and tries his best to court her.
Eating: His diet is mostly based on seaweeds and fruits. He loves watermelons and coconuts but it's not easy for him to find them, so this one was brought and prepared by his crush, Heena. Also, you can see the engagement stone in his hand bracelet. This stone is firstly worn by males and then given to the merman's partner when he's accepted by his love interest. So, the presence of the stone means he's single.
Exploring: One of his ways to express his care and love for Heena is to make jewelry for her and gifting her beautiful stones or sea shells. He can invest a lot of time finding the perfect one for her. The blue fishes are actually his helpers, he has quite a few. He is able to control them mentally and they can perform simple tasks for him like searching things, watching an area and alerting him of anything strange.
Sleeping: After a long day of exploring and playing with Heena, he rests in the depths of the sea. It seems he's having some nice dreams!
