Summary
Michael Afton was only five years old when his world changed forever. Born from the love between William Afton and Roselle, an enigmatic woman with ocean blood, Michael inherited a secret: he is a merman. His mother taught him to love the water, to respect its power... but also warned him of the danger of revealing it.
Everything falls apart when William returns from one of his extended business trips with heartbreaking news: he has a mistress, is pregnant, and wants a divorce. Roselle, devastated, commits suicide. Michael is torn from his home and taken to another country, to a new life with his cold stepmother, two curious stepbrothers, and an emotionally absent father.
At just five years old, Michael is forced to hide his true nature. A simple drop of water can trigger his transformation in just ten seconds. His gills, his sea-like tail, his connection to the ocean... everything must be kept secret.
But the power of the sea is not so easily contained. Michael's emotions—anger, sadness, fear—threaten to overwhelm his abilities, and he's already lost control more times than he cares to count.

Summary
Reader x like everyone ever with every bad trope my shriveled mind could think of!
Wrote this while I should have been doing math, made the plot crying laughing with my friends. READ AT YOUR OWN RISK THIS IS PURE STUPID
Also I do not ship annnny of the characters in here at all, all fictional fun <\\3
*******************************
I stared myself down in the full length mirror in the dingy attic that is my room. My sweatshirt looked so big on my petite 2’1 frame, that it hung down to my butt. I wrapped my golden locks carelessly into a messy bun. I don’t care about how I look. My brilliant blue orbs remind my mother so much of my dead dad that she forces me to wear thick glasses. I stumbled down the stairs clumsily. Ugh. I hate being petite and clumsy.
“Y/N!!! HURRY UP!” Called my cruel mother.
“*sigh.* coming mother!”
When I made it down to the kitchen, my ugly evil mother was smiling maliciously.
“I have decided to send you away.” I fell back in shock, my perfectly pink lips agape in astonishment.
“Wha-wha-what?” -
