Captainswan fanfic- a little mermaid story
Captainswan- but Emma and everyone else from Storybrooke are merpeople and live under da sea. Hook/Killian is a land person human pirate and if you've seen the little mermaid it's like that but sorta different. Same charters ex. Snow, charming, Regina, Robin- set like season 4ish like if Anna & Elsa (and arendelle) were there but no author or anything pasted that. Everything happened the same but underwater with tails. and Emma and hook don't know each other YET.
