Yandere Frank Castle x Fem Reader
1. His Obsession is Not Innocent. Frank’s obsession isn’t just about protecting you — it’s rooted in something far darker. He watches you like he’s guarding treasure, but his gaze lingers too long on your bare skin, your sleepwear, your underwear hanging in your bathroom. He tells himself it’s just watching over you, but he knows it’s not. He’s not some teenager with a crush. He’s a man who's killed hundreds. And the way he fixates on your body? It’s predatory.
2. He's Been Inside — and Not Just the Apartment. Frank has snuck into your apartment more times than you’d believe. He knows what perfume you wear, the texture of your sheets, the rhythm of your breathing when you sleep. He’s stolen a pair of your panties — not to keep, but to hold when he’s watching footage of you in the shower. He doesn’t even touch himself most of the time. He just stares. It’s ownership, not lust. But when he does let it out? It’s violent. Guttural. Like something animal finally snapping its chain.
3. He Uses Surveillance for More Than Protection. Frank has every angle of your home covered. The bathroom. The bedroom. He listens to your soft moans when you touch yourself. He watches with clenched fists, breathing heavy, his jaw tight. He hates that you’re doing it without him. That you're wasting it. He whispers under his breath, “That’s not how you do it. Let me show you...”
4. Touching is Inevitable. You fall asleep in your apartment. You wake up feeling like someone’s touched your thigh — your blanket is a little off, your underwear twisted. You think it’s a dream. It’s not. Frank snuck in. Just for a moment. Just to kneel beside the bed and touch the skin he’s memorized on screen. He convinced himself it was just to "check on you." But the second he laid hands on you, he couldn’t stop. Not until he saw you shiver in your sleep, and whispered, “Mine.”
5. If You Date Someone, He Makes It Graphic. He doesn’t just remove your lovers. He punishes them. Castrates them. Makes sure the body is found with evidence of what Frank thinks they wanted to do to you. It’s not about justice. It’s territorial. “You don’t get to touch what’s mine,” he murmurs, lighting a match and watching the aftermath burn.
6. He Starts Talking To You While You Sleep. He whispers in your ear when you’re unconscious — drugged from a laced drink he gave you after “saving” you from a break-in he staged. “I watch everything, baby. I know what you like. I could make you feel good... not like those little boys who don’t know what to do with you.” He kisses your shoulder, your temple, maybe lower. Never enough to wake you. But enough to leave a mark. You wake up with faint bruises and can’t explain why your inner thighs ache.
7. He Gives You 'Gifts' That Aren’t Sweet. You get a package. Inside is a ziplock bag with bloody jewelry — something your coworker wore. Inside the box is also a vibrator. Unused. Expensive. With a note:
“Use this when you miss me. No one else will ever satisfy you again.”
8. His Anger is Pure Possessive Rage. You post a photo online showing skin? That night, someone breaks into your apartment, ties you down, and lectures you through gritted teeth:
“You want them to see this? You think they deserve to look at what’s mine?” He doesn’t even undress you. He just holds you tight, his breath hot against your throat, touching nothing — yet it feels like everything’s been violated.
9. He Forces You to Say You're His. The night he finally reveals himself, it isn’t romantic. He’s on top of you, not pinning, but caging. Eyes dark. Lips inches from yours.
“Say it. Say you’re mine, and I’ll stop watching. Otherwise, I’ll put a bullet in every man who’s ever looked at you.” You cry. You fight. You scream. But when you break, when you say the words he needs to hear — "I'm yours..." He kisses your forehead and says softly: “That’s my girl.”
10. You’re No Longer Free. You’re Caged and Kept. You wake up in a secure location. A private bunker. Underground. Food stocked. Bed warm. He enters every day, shirtless, stained with blood, hands rough. He keeps you clean. He brings your favorite books. And at night, you hear him through the thin wall, whispering your name like a prayer while he touches himself to the sound of your crying voice.
🔐 ENDGAME: You’re a Pet, Not a Partner
Frank doesn’t want love. He wants obedience, silence, and submission. One wrong move, and he’ll break every bone in the world to keep you tucked in the dark, where no one else ever touches what he’s claimed.
