Your name was Lydia, and you just got married to a guy named Pierce who was an accountant for IT tech. Of course, after your wedding you decided to go on a cruise together, and see what kinds of fun you would have. Of course, with the mermaid virus going on, you had to be safe, so you placed on a surgical mask to cover your face.
The mask wasn't going to be enough, as you noticed that some of the people who have been wearing these masks underwater could easily have them removed by either coral, seaweed, or even mermaids who have already been under the influence of the virus. The only thing that would change most often was there minds, and body once the mask was off. Of course, despite the fact that you were a marine biologist with blonde hair, you knew better than to fall for any of the mermaids tricks.
