I was with my friends erwin and hanji and we stay out I saw many wave out and i smirked "got ya ya little fucks" I said and I started to ride it and saw hanji as the wave crashed over us and hanji got out of it I didn't my board shot Joan's I fell falling deeper I tried to swim up but I couldn't make it I faded into black

Erens perspective
I swam around until I saw something probably just more trash humans were disgusting creatures the didnt care about anything but themselves is mermaids kept fish healthy by cleaning the water I swam over and saw it was a stunning human I grabbed him and swam to a island I got him on it and my tail turned into legs so we could camouflage with humans I gave him cpr and as he woke up I screamed I knew he would get suspicious so I jump in the water and swam away to my castle i knew he needed to eat so I grabbed something and put it in a bubble and  floated it to the island I swam up secretly and hid behind a rock as he ate the food he looked over at where I was I stayed dead still and when he looked away and I swam away and went back to my castle I blushed as my fin turned into legs again and I wrote in my diary

I found someone I love and it's a human
