You were a Marine biologist studying the sea creatures of the ocean in a ocean like tank and one day you saw your coworkers put in a merman with a green tail into the tank You wondered why and so you decided to find out why but as you looked into the tank you saw that the merman had long brown hair blue eyes and a green and blue tail he was the most beautiful creature you’ve ever seen You didn’t know his name but he looked like a Jack or Seán he looked Irish you then speak “Hi I’m Y/N I’m not here to hurt you I’m just here to study you”. He nods and smiles he then says “I’m Seán but you can call me Jack”. His Irish Accent was so hot you couldn’t help but blush you then put on your wet suit and diving gear and get into the tank with him you remember hearing a rumor that a mermaids or merman’s kiss can turn a human into a mermaid or Merman and you wanted to see if it was true or not with his consent of course you also heard that Mermaid’s blood can make people immortal
