It's For Your Own Good! (Deku Scenario)

A/N: Credit to @TheDankMemeMaster for the amazing drawing! This scenario was an interesting one to think about and I hope that what I wrote was (hopefully!) close to what the requester imagined :D 

Request: Maybe a scenario where yandere Izuku's darling has a dinosaur based quirk and when they get mad Izuku has to restrain them down from destroying the place and making sure they won't hurt him and themselves?

Typically, with a quirk as destructive as yours, you've learned to have good control over your emotions most of the time, for the safety of those around you. It was rare for you to ever lose your chill, but of course he had to go testing those limits.

Izuku. F*cking. Midoriya.

You both had been close friends up to this point, your relationship being one comparable to an older brother and his little sibling. You knew Midoriya was a bit... over-protective of you, but you had always assumed it was because he wanted you to be safe, ready to help you if your quirk activated on accident from a heated argument, Bakugou being an asshole, etc. Besides, Midoriya was a sweet boy who cared for all of his classmates, you knew he meant no ill will towards you, no matter how extreme his actions seemed.

But to even have the audacity to do this sh*t, you could feel your muscles tensing, skin rapidly changing color as your body began morphing, but you closed your eyes and took a few deep breathes, forcing yourself to calm down, no matter how difficult. 

Midoriya had tampered with your phone. Well, not really "tampered," per se, but he had sent your family member a text that you had not remembered sending. And for that, he had to know your phone password, and you don't remember telling any of your friends your password.

 The latest text you had gotten was your older brother asking if you were willing to go to Hawaii with him for the majority of the up-coming summer, as a way to get away from family and school for a bit. Your phone had buzzed with the notification while you were at Midoriya's house for an after-school study session, and you remembered smiling so wide that even Izuku had looked up from his notebook to look at you and smiled as well, though not knowing the reason why.

"Why do you seem so happy all of the sudden?" he chuckled, admiring your features as he noticed how your eyes seemed to sparkle with how excited you were. You quickly turned off your phone and set it aside, turning back to your homework sheets to see how much you had gotten done. "Oh, it was nothing," you dismissed, trying to hide your grin as you worked on the next few math problems you had. 

You felt a hand grasp yours, Midoriya leaning closer to you, practically overflowing with curiosity. "Please tell me! I've got to know what's got you so excited!" You blushed a bit from the proximity and looked away. 

Chuckling a bit, you released his hands from yours, standing up from the table to head to the kitchen to grab a drink. "It wasn't anything, 'Zuku. Don't worry 'bout it," you answered. You didn't want to distract him with your upcoming trip when you both should be studying. Opening his fridge, you grabbed a water bottle and took a sip, heading back to his room when you walked in on him peering at your phone with a blank face.

"MIDORIYA WHAT THE HELL?!" you yelled, running over and grabbing your phone from him. "Who's the person you were texting?" he asked simply, as if everything was normal. Under his normal tone, you could hear a slight edge to it, as if he seemed... annoyed?

Your phone screen was on and you peered at the texts:

Jacob🤡

Him: Heya Y/N, was wondering if you wanted to go to Hawaii with me this summer? Family has been a bit stressful so I thought it'd be nice

Y/N: No, I have plans with my friend. I'm sure you'd be fine to go by yourself.

Him: oh, k

-THIS USER HAS BEEN BLOCKED-

You looked up at Midoriya, anger rising at an alarming pace. "WHAT THE F*CK IS WRONG WITH YOU?! HOW'D YOU EVEN SIGN INTO MY PHONE????" you screamed, throwing the phone to the side and facing him. Midoriya noticed you morphing and he stood up slowly and responded with a calm, but oh so annoying voice: "I was just guessing and I got it right. I was curious as to why you seemed so happy!" 

All it took was a brief few seconds, but your quirk had you transformed into a large troodon, and with a quick leap you attempted attacking Midoriya, but he quickly got out of the way and pinned you down, his fist held tight around your beak to keep you from screeching. Your tail swung wildly, hitting Midoriya and knocking everything over. It stunned him- how hard the tail hit him on the back- and you took the chance to turn yourself over and spared no time in landing quick attacks all over the poor boy, resulting in his shirt getting shredded by your claws, even leaving a bloodied scratch mark on his face. You stood up in an attempt to grab your phone from the floor and run out of the house to try and cool down, but as your claws reached for the device Midoriya tackled you and shoved your larger form against a wall, and grabbed something from one of his drawers. 

He was using his quirk now, to keep you in place, but that didn't stop you from screeching loudly and trying to break free from his sturdy grasp. You needed to be alone to calm down! What was he doing?!

Before you could attempt to scratch him again, he placed something over your beak, and in a flash your vision became blurry, and soon, pitch black.

You woke up with a pounding headache, now lying on the hard floor in one of Midoriya's guest rooms. You were back to your normal human self, and sat up on your knees, realizing your clothes were gone, replaced with one of Midoriya's shirts and some bottoms. 'What the f*ck?...' you thought, looking at yourself. You began standing up, only to be pulled back down. 

Chains.

You were bound to the floor by your wrists and ankles with heavy, metal chains.

"MIDORIYA????" you screamed, panic rising. He entered the room, wearing nothing but a pair of shorts, and you figured it was because of the scratches that littered his body and face, all caused by you. Maybe you would've felt guilty if it weren't for the position you were currently put in. 

"UNLOCK THESE CHAINS, MIDORIYA. THIS ISN'T FUNNY," you yelled, body shaking and ready to transform again. "I need you to calm down, Y/N. Please? You sorta, uh... wrecked my bedroom, so I had to do this!

It's for your own good!"

You took a few breathes, and looked at him again, straight in the eyes. "I promise I'm calm, Midoriya. Now let me go."

He looked at you and then smiled a bit, walking over and petting your head. "I don't wanna take any chances. Would you like anything for dinner by the way? It's getting pretty late."

In a split second your head had transformed and you attempted reaching up to bite him, but he retracted quickly and chuckled a bit. "See? You just need a bit more time to adjust to the chains and calm down. You're gonna be here for awhile and I don't want you being uncomfortable. I'll make some f/f (favorite food) in the meantime, ok?" he spoke, getting up and walking out of the room.

You struggled against the restraints, angry tears forming at how trapped you felt. You gave up after a few tries, letting out exasperated cries as you curled into a ball and let the tears fall.

What did he mean by 'You're gonna be here for awhile' ?
