This chapter is super angsty. Midoriya talks about dealing with OCD, how his life changed dramatically because of it. 

Disclaimer: I do not have this particular OCD, or any type of OCD for that matter. I done some research on it, and if you happen to know anyone with it, or after reading this chapter think they're dangerous, the people with this illness are NOT. Yes, they have violent thoughts about dear loved ones, but have never acted on it. There has been no actual cases of someone killing another because they have OCD.

So please with that in mind, enjoy. 

3 days later/ next week

Todoroki rubs his eyes, brain weary from the lack of sleep. 

He searched all over the internet at the new found information on this illness Midoriya could have. But nothing attracted him more than this article, '5 Realities of Life When Your Brain Wants You to Murder'. 

"This is due to a form of Obsessive Compulsive Disorder called , which sounds like a drug Phillip K. Dick invented, but is actually a form of OCD that manifests as repetitive and extreme thoughts. They're most often violent or sexual in nature, but they can run the gamut from a religious person worrying that they're being blasphemous, to wondering if your partner is cheating on you. In my case, the intrusive thoughts were violent, although I guess a lot of people would also consider mass familial murder to be blasphemous.

It started when I was 15. I had been having disturbing thoughts for a couple of months and had been showing signs of anxiety for years, but for whatever reason, they hit me especially hard one day. I was watching an Ellen DeGeneres routine and I suddenly thought to myself, "Hey, what if you killed your entire family?

And I couldn't shake that thought. It kept crashing into me, over and over, like I was in a murderous wave pool. I started thinking about how easy it would be to do it -- I knew there were knives in the house, and OCD has a way of making the absurd seem horrifically feasible. By the time Ellen started making a joke about petting her cat, I was fighting back an actual, powerful urge to stab everyone present. This may not be an entirely normal response to Ms. DeGeneres' comedy." 

Todoroki blinks, finishing his breakfast. The article was oddly humorous, in a dark way. 

"Shoto!" Enji shouts slowly from the front door of the condo, and Todoroki is both amazed and disturbed from how loud his bastard father can be. His lips curl into a scowl as he remembers that Enji arranged a quirk marriage with someone he's repulsed by. 

"I swear to god, if I see that bitch today..." Todoroki shakes Yaoyorozu out his head. He closes his multiple tabs (deleting his internet browser history after) and locks his door, so his satanic father cant burst into his personal space. 

He picks out some clean clothes, going into the bathroom to wash up. After undressing, he steps into the shower, setting the temperature to his liking. His thoughts swim from plotting Yoayorozu's death to Midoriya. 

'He looked so upset.. he didn't even let me say goodbye. Does Midoriya hate me now? Did he ever like me like how I like him..?' Todoroki feels frost start to form on his right arm, the fingers massaging his scalp getting tangled. 'What if he never wants to see me again?!'

Todoroki eventually falls to the floor, hands tangled in his hair. The white tile is starting to blur in his vision, precisely planted rhombus' becoming disfigured hazy squares. His breathing is out of control, heart hammering loudly in his chest. He attempts to grab it, as if he could pull the organ out his body to end his suffering. 

"Why..?! Everything was perfect up until..." Todoroki stutters here, hissing as he forces air into his lungs.  His face is bleak, colorless except for his wild heterochromia eyes. He shakes, not because of his current panic attack, because of the laughter bubbling from his throat. 

"No! No, no, no, no! Everything can still be perfect! Yes, I can still have Midoriya and he'll want me! Yes, everything will be fine.." Todoroki smiles wide. The shampoo currently in his hair drips close to his eyes, and he quickly rinses it out of his hair. 

...

Now refreshed and dried off, Todoroki unlocks his room door. He eventually finds his father, and he smiles, a little too sweetly. 

"Excuse me father, but I have to go have a talk with my fiance." Enji scowls, looking rather pissed. 

"Good lucking finding her. She disappeared 3 days ago!" Enji spins around, facing away from his son. "Little harlot ruined my chance at heirs that aren't insane... now I won't be able to raise a strong grateful hero my way." 

Todoroki looks at the disgruntled man, amused his plan had failed. He wasn't even upset that Yaoyorozu was missing- after all, her loss is his gain- and makes his way back to his room, locking the door behind him. Todoroki opens up the article again, skipping ahead a little. 

"I usually don't have impulses about harming someone unless I'm very close to them, because OCD tends to attack you right where it'll hurt the most. But there's no ideal way to tell someone "I'm having an urge to plunge this steak knife into your throat because I love you." Only my parents and a couple of trusted friends know the full extent of what I've gone through." 

Todoroki was about to scroll down, when something in his brain clicks. 

"Did... Midoriya kidnap Yaoyorozu?" 

- 

Yaoyorozu's eyes open slowly, head just dead weight on her shoulders. Slowly, her eyes adjust to the dim room, and realizes this is not her home. 

"W-wha?" Her tongue feels heavy in her mouth, hands grasping the concrete and rising her weak body off the floor. 

"Ah, you're awake." Midoriya smiles, looking at the confused girl. He was sitting in a chair, legs parted and resting his arms on them. "I was starting to get worried." 

Yaoyorozu looks at him, before her memory started to recollect. 

"You...! You did this! You kidnapped me!" Yaoyorozu rises off the floor quickly, but immediately doubles back,  groaning from the sudden headache. Midoriya stands, worrying over her, before she fends him off. 

"Get the fuck away from me! What the hell is wrong with you?!" Yaoyorozu creates a staff, though it only came out half it's size. 

"I wouldn't be creating weapons if I were you," Midoriya mutters, dodging her attacks. "You haven't eaten in three days." 

Yaoyorozu gasps. "I missed my date with Shoto!" Midoriya's gaze darkens, thinking. The 3-D printer creates a small object, a tracker it seems, and Midoriya speeds towards her, crushing the device in an instant. He pushes her to the ground, knocking the wind out of her. 

Yaoyorozu sputters out some form of distaste, and Midoriya bends down and whispers into her ear. 

"Y'know, I really, really wanna kill you." Yaoyorozu stills as soon as that statement leaves Midoriya's lips. 

"The thought has reoccurred so many times in my mind. You'd die in so many ways.. I'd stab you with one of your own creations... You would die of starvation.. or the obvious, I could just break your neck. Twist your head around until it pops off.." Midoriya mutters, staring into space. 

Yaoyorozu stares in disbelief, looking sick to her stomach. Not only did the dubbed 'Cinnamon Roll' drug her and kidnap her, he planned her death..? 

"Wanna hear a story, Yao-momo?" Midoriya inquires, settling back onto his chair. Yaoyorozu doesn't answer, in fact she can't even move. 

"I was about 13 when it started. Kacchan and I were not on best of terms. He bullied me alot, and one day after school, I just suddenly thought, 'Hey, what if you killed Bakugou?' I was sick to my stomach when it came to my head, in fact, I threw up then and there. Later that day, I was helping my mother make dinner, and suddenly, it happened again. 

'What if you were to sink this knife into your mom's neck?'" 

Midoriya stalls here, lip trembling. Pulling in a deep breath, he continues. 

"They didn't stop. The thoughts didn't fucking stop after that, no, they increased. Anything in a any room would trigger a violent thought. 'How 'bout you stuff this toilet paper down your mom's throat?' 'Hey, let's smash Bakugo's head into this random playground equipment?' 'Ooh, All Might's face looks real appealing to stab right now.' 

"I never acted on these thoughts. So they'd start to change routes. What was once violent became extremely sexual. Oh god, I hated myself. I hated myself for having these thoughts, and walking home one day from school, I decided to kill myself." 

Yaoyorozu shakes her head, sweat beading from her scalp. 

"N-no, shuddup, stop telling me these things.." Yaoyorozu opens her eyes, guilt and anger swarming them. "Just because you're insane doesn't give you the right to kidnap me!" 

"... But I'm not insane.." Midoriya says softly, eyes burning from held back tears. "After that.. I met the sludge villain. He almost killed me, but All Might saved me. Afterwords, All Might helped me gain more muscle, and that's when my quirk started to form. I was still experiencing these thoughts, and I finally got the courage to tell my mom..." 

He looks at Yaoyorozu with anger heavy in his voice. "I learned I had OCD, but a different type. It caused me to have violent or sexual thoughts. It was perfectly normal, and he said I should call myself a hero for not acting on them. I am taking medications and going through therapy. I still have these thoughts, but they don't bother me much now." 

"So why am I here? If you're not gonna act on these thoughts?!" 

"Because I met Todoroki." Midoriya says simply, eyes twinkling. "He was so broken, filled to the brim with hate... I wanted to make him happy. Make him mine. Only mine. You just want him for looks and money, I want him to be happy and smiling. So I developed a Yandere behavior." 

Midoriya walks over to a table, filled with different types of weapons. Yaoyorozu's face blanks as Midoriya looks through. "I want you dead. Not because of my illness, because I want you to be gone, far away from Todoroki-kun." Midoriya grabs a stack of textbooks. He drops them next to the chair he was sitting in.

"These are some very interesting things I found combing through the dark web." Midoriya picks up a book, reading the cover. "Ah, this ones about 16th Century torture devices." 

Midoriya smiles innocently. "Maybe when we're finished, you can make one, and we'll test it out." 

Yaoyorozu's eyes widen as she figures out what Midoriya is planning. 

Mind Break. 

"We'll see who's insane after this..."

Sneak peek of Chapter 7: 

Jiro is one if the three students still seated, her chair turns towards the empty seat.

Her stomach still churns at their last conversation, and she wishes she could take it all back.

"I shouldn't have come out to her like that.." She whispers, and looks at her phone, contact still on Yaoyorozu's.

13 attempted calls. 20 messages unread. Jiro's eyes were starting to burn, tears unshead.
