Yandere Deku Headcannon

A/N: This is the first "yandere" type thing I've ever written, so if there is stuff I can improve on pls tell me. Also I guess requests are open? Again, I'm sorta new to this so bear with me.

- This lil' bean is the delusional, lovesick type of yandere. He feels as though the both of you were just meant to be. It's endearing and cute at first, seeing how much he seems to adore and look up to you. Harmless, right? Deku would never hurt a fly... right?

- He probably either knew you ever since childhood like with Bakugou, or met you the day of the exams to get into U.A. Either way, you were always sticking up for him and overall just being kind to him. After all, he's just so cute! 

- Ever since the two of you met, Midoriya knew that you were the one. From the moment you smiled at him and stuck up for him when Kacchan would bully him when no one else would, he knew that the both of you were soulmates. No doubt about it.

- It begins with him spending as much time as he can with you, learning about your likes, dislikes, hobbies, quirk, relationships, everything. He makes sure to write down everything in his special little notebooks dedicated to everything about his darling Y/N. 

- His obsession with you only gets worse as you both enter U.A. He gets constantly stressed that some other boy in 1A will try to take his place as your "best friend" (at the time, you considered Deku your closest friend). 

- Added on to that stress is the Hero Training. He acknowledges that you and your quirk are plenty strong, but what if you accidentally hurt yourself, or lose a fight with a fellow classmate? What if something happens and he isn't there to save you or tend to your wounds? What if you get killed?  

- Eventually all these paranoid and antagonizing thoughts get to him and he kidnaps you quite literally the day you both graduate. He had his plan all thought out ever since the first day of your third year.

- After the graduation party, Deku finds a way to drag you away from the commotion, pouring the both of you a drink as you stand by a balcony, talking about all the fun times you had and what will await in the future. You suddenly get very sleepy, and ask Midoriya if he could possibly bring you back home, thinking you were just getting drunk. After all, you trusted your lil' Izuku with your life, after him being by your side all these years. He wouldn't take advantage of you, he just wasn't that type of guy, you were sure of it. He says sure and you pass out in the back seat as he drives you away from school, past your house, to a special little place he prepared for the both of you. Somewhere very, very far away...

- You wake up in an unfamiliar room on a very soft bed. Confused and still a bit dazed with a headache, you attempt to get up, only to realize both your arms and ankles were chained to the bed, only allowing enough slack for you to sit up and nothing more.

- You attempt to use your quirk to aid you in an escape, only to realize that you were wearing a quirk collar around your neck. You had also realized in this moment that you were wearing some very... revealing pajamas. Though comfy, you were most certainly uncomfortable and beginning to freak the f*ck out. 'Oh god, was I raped? What's happening?! Where the f*ck am I?!' Your panicked thoughts ran through your head at top speed. You begin to scream as loud as you can, only for you to see the bedroom door open.

- "Ah, darling, you're awake! I bet you feel so well rested, hmm? That was quite the long sleep you had! I might've added a bit more to that drink than I should've..." It was Izuku. "M-Midoriya? Did you do this?!" You were in disbelief. Your closest friend, the one you trusted most, with your life even, would betray you like this?

- He smiled at you. "Of course, silly! You had no idea how long I waited to bring you here, where you can truly be safe..." He reached out to you to place his hand on your cheek but you violently flinched away, glaring at him. "YOU F*CKING PSYCHO, LET ME GO-" You were cut off by him embracing you in the tightest hug you've ever felt. You struggled against him, trying to force him off you, but his time at U.A, plus his quirk, made him definitely stronger than you, with or without your quirk. You eventually gave in and let him embrace you, telling you how well he will treat you and that "everything is going to be ok." He was f*cking insane for doing this, but deep down, you knew you could never physically hurt him in any way. At least not with the intent to kill or cause him great pain. He was Izuku after all, the boy who has been your best friend for basically all your life. 

- Now realizing that you may never escape, you begin to struggle again, only instead of screaming and yelling, you begin to quietly cry. Izuku pats you softly on the back as he murmurs little "words of comfort" into your ear

- "I know, love. I know. It's a big change, and you're stressed. Don't worry, you'll see that this is a safe place. You'll forever be safe here with me. I love you~"

Other Notes:

- His nicknames for you: Sunshine, Darling, Love, Boo, Sweety

- Mostly into just snuggling with you and soft kisses, and is willing to wait until the Stockholm Syndrome sinks in (or as he prefers calling it, "Realizing how much you both need each other") to move onto more "heated" stuff 

- Despite him being the #1 Hero keeps him quite busy, he always tries to make time for his little darling every day

- Ever think of possibly escaping? Don't even try. With him being the #1, he makes a lot of money, and is easily able to afford high-tech locks and security, so even if you escape the house, his cameras will capture everything, meaning he can see what went wrong and fix it, and he can clearly see where you went and re-capture you within, at the most, three days, depending on how fast you can run and how good you are at hiding. I mean, he's the #1 Hero. He is very hard to avoid or hide from in public.
