Yandere!Merman x Surfer!Reader
Yandere!Merman didn't start off by pulling you under. Instead, he chose a slow, agonizingly patient courtship that took months to build. At first, he was just a mysterious silhouette swimming alongside your board out past the break. You’d catch flashes of shimmering teal scales under the water, or see a pale, webbed hand casually gripping the edge of your surfboard when you weren't looking. He wanted you to get used to his presence, turning himself into a regular part of your daily surf routine.
The gap finally closed when he realized you weren't afraid of him. he started popping his head completely out of the water right next to your board, his long, dark hair plastered to his face and his slitted, bioluminescent eyes blinking up at you. You’d just sit cross-legged on your surfboard, drifting on the gentle swells, completely mesmerized as this beautiful, dangerous creature rested his chin on the nose of your board like a curious seal, clicking and purring softly whenever you spoke to them.
Yandere!Merman became completely obsessed with "providing" for you, though his understanding of human logic was incredibly warped. he noticed that you spent hours out on the water without eating, so he decided it was his job to feed you. he would disappear beneath the waves with a powerful flick of his tail, leaving you waiting on your board, only to burst through the surface a few minutes later holding a completely raw, wriggling deep-sea fish in his claws, proudly offering it to you with a wide, fanged grin.
When you laughed and shook your head, trying to explain through gestures that you couldn't eat raw, moving fish, he didn't get discouraged. he just swam closer, floating on his back right next to your board, and began meticulously cleaning the fish with his sharp claws, trying to hand-feed you the raw pieces himself. He would pout, letting out a low, disappointed click from his throat whenever you gently pushed his hand away, utterly confused as to why his favorite human was refusing his hard-earned hunting trophies.
Yandere!Merman gift-giving got a lot more creative when he started raiding sunken trade ships and coastal orchards that dipped over the cliffs. One afternoon, he swam up to your board with his webbed hands overflowing with weirdly preserved, salty pears that had fallen into a nearby cove. He pushed them onto your lap, watching with absolute, unblinking intensity as you took a bite of one. The second he saw your jaw move and realized you were actually eating his gift, his gills flared with excitement, and he let out a loud, euphoric trill that vibrated right through the fiberglass of your board.
You became entirely addicted to this secret routine. You started spending less time actually catching waves and more time just sitting out past the breaker, staring down into the clear blue water, waiting for his shadow to appear. And he loved every second of it. He loved watching you watch him. Every time he dove back down into the reef, he would purposefully swim in elegant, showy loops right beneath your board, flaunting his massive, powerful tail just to keep your eyes locked entirely on him.
Yandere!Merman weaponized this sweet, domestic routine to slowly erode your attachment to the land. While you thought you were just making a unique marine friend, he was tracking your schedule, learning your scent, and making you entirely dependent on his daily visits for excitement. He’s currently letting you stay on top of your board, completely satisfied with hand-feeding you fruits and preening under your attention. Still, his possessive instinct is just waiting for the perfect, stormy day to permanently bring his favorite surfer down into his world for good.
