You’d known Bakugo Katsuki since you were kids—rivals, best friends, and everything in between. From the moment you could basically talk, the two of you had been inseparable in everything. Still, for all the sparks that flew between you, there was one truth you’d never let him see.

A secret you had to guard with every breath.

You were a mermaid.

Well—half. Your mother, a graceful being of the sea, had gifted you a pendant at birth: a sea-glass necklace that allowed you to walk on land like any other human. As long as it stayed around your neck, you could pretend to be normal.

You never took it off. Until today.

“Hey!” Bakugo called from the kitchen of his house. "You better not be eating all the damn snacks!” You rolled your eyes, already setting the tray down on the living room table.

He stomped in with two cans of soda. And that's when it happened.

His elbow caught the edge of the tray, sending one of the cups of water flying. You didn't even realize your necklace was in your bag, forgotten after a quick shower post-training. A second later, water soaked your arm.
