Chapter 1

TW: Kidnapping and drug use!

--

Katsuki Bakugo was an alphan pro-hero. The number one to be specific. He was on top, where he always wanted to be. Although, there was always something strange about his job.
Katsuki had a friend named Shoto Todoroki. They became friends throughout their highschool years, but Shoto suddenly disappeared at the ripe age of 19. He was pronounced dead a few days after his disappearance. It left everyone broken, his friends, his family, but most importantly Katsuki. He didn’t realize he had grown so close to the dual haired male. They didn’t have a lot in common. Hardly anything, in fact.

—

Shoto Todoroki, an enigma. He constantly had omegas attempting to court him, even a few alphas and betas. He was interested in none but one, Katsuki Bakugo. He knew the alpha would never even attempt to court him, especially since the blonde started to court Denki Kaminari, an omega. He couldn’t help but feel a burning hatred in his chest everytime he saw the two hanging out together, and it especially got worse when the electric omega accepted Katsuki’s courting within the second month of school.
The alpha being mated made him livid. He decided to run away, fake his own death. He became a villain, becoming his brother's apprentice. Toya Todoroki- or, better known as Dabi, gladly took his younger brother under his wing and helped him to disguise himself in public.

Current time-

Katsuki couldn’t lie, being number one was stressful. To add the cherry on top, Denki, his mate, was heavily pregnant. With the mood swings and the extra stress of worrying about his omega, Katsuki barely had time to himself. He was at the right spot in life, he was where he always wanted to be. 22 years old, married, and number one. He was sure nothing could go wrong, right? His life was perfect!
He was on a late night patrol, messaging his mate.
K. : ‘What do you want for dinner? I’ll stop by somewhere after work.’
D. : ‘Can you pick up some udon? You know how we like it!’
K. : ‘Sure, I’ll see what's open, I love you babe 💗.’
D. : ‘I love you too ❤️’
Katsuki slightly smirked at the message. He hopped down from the roof he was on, using a small explosion to cushion his fall. He walked to his agency.
“Boring patrol. Nothing even happened.”
The alpha huffed, stuffing his hands in his pockets. He heard something behind him, turning to look. He raised a brow and ‘tsk’ed as he didn’t see anything. Suddenly, he felt a cloth over his face. That’s all he remembered before blacking out.

–
“An alpha? Seriously, Sho. There were plenty of omegas out that you could’ve grabbed.”
Dabi, a fellow alpha, said as he looked between the tied up blonde and then to Shoto.
“You told me I could take what I wanted. He’s what I want.”
Dabi laughed in his younger brother’s face upon hearing that.
“Y’know, this alpha actually has a pregnant mate. You could’ve taken him. Or- well, he would be used goods. I mean, another alpha’s pup? What would you do with that?”
Shoto hummed and nodded , agreeing. He looked over Katsuki, staring at his calm expression. He felt proud. Like he had rescued the poor alpha, no. Like he had rescued his omega. Shoto felt determined to bring this man to his senses and make him realize he was meant to be an omega. He was meant to be his bride.
After a few moments of watching, he looked over to the table beside them. He grabbed a needle, injecting Katsuki with some kind of liquid.
“This drug is meant to speed up his transition, right?”
The scared man asked, looking at the black haired male .
“Of course. I know you want to get him as fast as possible. It’ll also fuck with his brain a bit, twist his memories. Dunno how exactly, but he’ll remember he was an alpha and that he ‘wanted’ to transition.”
He replied, smiling at his brother. Shoto softly smiled and nodded, placing a band-aid over the injection area.
“Perfect, how fast should it work?”
“Inject him with it every hour and the change should be completed within the next month. That time point isn’t taken into consideration, you being able to change his body yourself. Reminder, enigmas can force alphas into transitioning. But, you will have to court him and such, there’s no drug that’ll make him just automatically fall in love with you, unfortunately.”
He groaned upon hearing that , punching the table.
“Seriously? I guess I’ll just have to wait then. Leave us alone now.”
Shoto told Dabi, who nodded and left. Shoto hummed as he looked over Katsuki again, smiling as he walked over and stroked over his cheek.
“Finally. Don’t worry, Kat. I’ll save you from your stressful life. I’ll make sure you feel no stress ever again. You and our future pups will never have to worry.”
He said, talking to him even if he was still out. He looked down at Katsuki’s stomach, growling under his breath.

A couple of hours later, Katsuki groaned as he woke up and quickly looked around.
“Where am I!?”
He asked, blinking so his vision could focus. He noticed someone in the corner.
“Hello? Who are you? You better come out, you dunno who you're messing with!!”
He growled, attempting to use his quirk.
“You know exactly who I am, my love.”
Shoto said with a wide smile, stepping out of the shadow he was hiding in.
“What the-?! No, you’re not Shoto. He died 3 years ago!”
Katsuki argued, getting a laugh in return.
“I can assure you, I am Shoto Todoroki. I’m not dead, I just decided to.. take a different path.”
He told the blonde, smiling at him. Katsuki looked almost terrified, something he’s never seen before. It made him worry.
“Don’t be scared, I don’t plan on hurting you. I would never hurt my omega.”
Shoto purred to him, gently cupping his face.
“What are you talking about. I’m not an omega, nor am I your omega. Speaking of that, where’s my mate?!”
Shoto snarled, feeling the old burning jealousy return.
“He’s fine. He’s at your house, I’m sure he must be worrying about you. But, if you want him to stay fine, you’ll listen to what we say. Don't cooperate? We’ll bring him in and kill him and that disgusting thing inside of him right in front of you. So, what’ll it be?”
Katsuki quickly looked worried. He couldn’t let that happen, the guilt would never go away. He sighed, knowing he had little to no choice.
“Alright, can I at least be untied?”
He asked, hoping to trick him.
“No. At least, your hands will stay tied until I can trust you.”
Shoto said, grabbing another needle. He grabbed Katsuki’s arm, giving him another dose.
“HEY! What is that!?”
Katsuki asked, knowing not to squirm. He faintly whined at the feeling in his body from the medicine.
“Don't worry about that. You’ll know what it is soon enough.”
