Twinkling Sea Stars (An Eridan x Mermaid! Reader)

Yup. You're a mermaid. I wanted to try something different, I have big plans.
Your name is (Y/N) (L/N). You have a secret. Ever since you were little, no matter how big or little of an amount, if your legs touched the water, you would instantly grow a tail. Yup, a mermaid tail. One day, you met this... strange guy. His name is Eridan, Eridan Ampora. What happens when you two become friends?
WOW I SUCK AT DESCRIPTIONS HAHA
