Misuse of Power (Yandere My Hero Academia x F!Reader Oneshots)

My Boy (Amajiki Tamaki)

Requested on Tumblr. It is a mystery why I call him Tamaki and not Amajiki but it is a habit I cannot break.

Title: My Boy

Pairings: Amajiki Tamaki x Reader

WARNINGS: Yandere themes

Summary: Tamaki's dedication ran deeper than you thought.

"My boy's an ugly crier but he's such a pretty liar...

...My boy, my boy, my boy

He ain't a man and sure as hell ain't honest"

-from "My Boy" by Billie Eilish

You never could have seen it coming.

Tamaki was the perfect boyfriend. It was like he could read your mind- know exactly what you wanted before you knew you wanted it.

Texted a friend you wanted Chinese food? He'd be on your doorstep, holding a bag of Chinese food no more than an hour later.

You needed to go shopping? Done, done, and done! He would even grab things you never put on your shopping list but desperately needed.

You thought Tamaki was just really intuitive. You thought it was just that he knew you so well.

You thought he was just a good boyfriend.

—-------------------------------------------------

Soft music played throughout the bar. It was a quiet night, with you and your friends being some of the only people there. It wasn't a well-known place, so it wasn't surprising that you were nearly alone, seated at a table near a window.

"So Tamaki couldn't make it?" Nejire asked, downing a cocktail in seconds.

"Yeah," you said, a little sadly, "His shift ran late today."

"But you get to spend more time with us!" Nejire squealed, taking your hands in hers and squeezing tightly, "I've been trying to set something up for so long!"

She had? As far as you knew, you only ever saw Nejire at group hangouts. You can't imagine that you'd missed any messages from her, even if her only contact to you was through Tamaki.

"Well, we're all together now," Mirio hiccuped.

Mirio had gotten here before the both of you. He was several drinks in and he was not someone who could hold his alcohol.

He turned to you, "I'm surprised you and Tamaki aren't married already."

"Yes, well," you chuckled awkwardly, "We're taking it slow."

"You're taking it slow," Mirio countered with a laugh. He had made similar jokes before but Tamaki was always there to lead his best friend away, saying "Okay, okay, you've had enough to drink buddy."

You almost let it slide. Almost.

"What do you mean? Does Tamaki want to marry me or something?"

"Does he want to marry you?" Mirio laughed, "He's had your engagement ring picked out before you two started dating."

You and Nejire stared at him.

"You mean that... figuratively, right?" You asked quietly.

Mirio seemed to realize he had said the wrong thing, because he suddenly tried to change the topic, "Did either of you see last night's Saturday Night Live?"

"Mirio," you asked, trying to sound casual despite your pounding heart, "How did Tamaki act before we started dating?"

"Well..." Mirio took another sip of his beer, "He was always over at your house, hanging out with you or whatever."

Your heartbeat spiked. Tamaki had never come over to your house until a month after you had started dating.

"He had a lot of pictures of you on his phone, since you were, you know, friends before lovers or whatever."

You thought the first time you met him was when he asked you on your first date. And you hated taking pictures.

What the hell was going on? Had Tamaki been...stalking you?

Cold fear was starting to settle in your veins and you were suddenly questioning everything.

All those months of feeling like you weren't alone, all those walks home where you felt eyes on the back of your head, all those feelings that you thought went away because you had a strong, heroic boyfriend... Was that because of him?

Nejire was usually kind of air-headed, but when she sensed something was wrong, she was quick to act and became serious fast. "Give me your phone."

You put the password in and handed it over, still going over your entire relationship in your head.

Nejire searched for a second, then showed the screen to you, tapping on an app you hadn't noticed before. It looked innocent enough- like a calculator app, but not one you remembered downloading.

"This is a tracker app," Nejire explained, anger seeping through her words, "It tracks your location and sends all your texts to whoever it's connected to. And I'm pretty sure that person is Tamaki."

A chill ran down your spine. When had he done this to your phone? To you?

Mirio had passed out cold. Nejire turned to you, looking worried, "What are you going to do?"

"Whatever I have to," you said softly, pulling out your wallet to pay for your drink.

—---------------------------

Tamaki walked through the door, hanging his coat on the hanger and turning to go to the bedroom. To his surprise, the living room light clicked on, revealing you sitting in the recliner, looking three parts angry and one part terrified.

"What happened?" Tamaki asked nervously.

"Did you stalk me?" You demanded to know.

Tamaki froze. How had you figured it out? What was he supposed to say?

"N-no, baby, I would never do that to you," Tamaki soothed.

"Mir- someone told me that you went over to my house and had pictures of me on your phone... before we dated."

"They're lying!" Tamaki's voice went up an octave, his face twisting in panic. He was never good in stressful situations. He never thought you would ever find out what he was like before your relationship. Or during, for that matter.

"What about the app on my phone?" You demanded.

"Baby, baby," Tamaki put out his hands like he was approaching a wild beast, "I would never, ever do anything to hurt or scare you. I promise."

You shook your head, "With all I've heard and with the app I found, I don't think I can stay in this relationship," you said, getting out of the chair and walking past Tamaki, "I've already got my stuff out of here. So we should go our separate wa-"

You stumbled forward when Tamaki threw himself to the ground, wrapping his arms around your legs. A loud wail cut through the quiet apartment's air. It took you a second to realize Tamaki had buried his face into the back of your legs, wetting them with his tears.

You looked down at him, a mess of tears and snot, body wracked with sobs, big watery eyes staring up at you.

"Tamaki get off-"

"NO!" Tamaki screamed, "No no no no NO!"

"Wha-?"

"You can't leave me. I've worked too hard and for too long. You can't ever leave me. You can... you can stay here!" Tamaki let out a broken laugh, still sniffling as tears poured down his cheeks.

"Get off of me," you tried to move your legs but it was no use, Tamaki wasn't budging.

And his eyes had turned from tear-filled to furious.
