Two species, one love | R!Donnie x Reader | StrangerThings+ROTTMNT

When mutants became normalized and started roaming in other places than the Hidden City, a lot of people were skeptical with the change. Especially your older brother, Billy, who was involved with a lot of gang events. Some of your friends were skeptical, but ok like Lucas, Dustin, Max, and Nancy. Some didn't care like Eleven, Mike, and Eddie.
But everything changed when you went to a dance, and saw a particular turtle that caught your eye.

Donatello was a man of his word.. Most of the time. He always told himself that he would never date until he was an adult because it would get in the way of his life. His brothers love the surface, but humans treat them differently at times. He and his brothers, along with other fighting mutants would defend themselves when the humans would vandalize the mutants, or vice versa. However, an event happened, causing Donnie to never participate in those events again. But when Leo somehow convinced everyone to go this dance, Donnie sees a young human girl and something sparked in him.

This is based on the 2021 version of West Side Story, but the gangs roles be swapped a bit. Even if you haven't seen the new or old WSS, you don't need to because this story will be altered around a bit to match up. In this AU, Mikey is 15, Leo+Donnie are 16, and Raph is 17. You are 16, and the original ST characters are the same age and this takes place in "New Indiana" (New York and Indiana mixed together) during modern times.

I DO NOT OWN ANY CHARACTER EXCEPT FOR A FEW MUTANTS.
STRANGER THINGS BELONGS TO THE DUFFER BROTHERS, THE TURTLES AND MUTANTS BELONG TO NICKELODEON, AND WEST SIDE STORY AND THE JET NAMES BELONGS TO ARTHUR LAURENTS.

I thought of this idea and it kind of reminds me of some a Undertale AUs.
