AKA: izuku goes THROUGH it. Katsuki is the best alpha ever. And dadzawa.

Basically, my own experiences and favorite tropes blended together.

Chapter 1: I'm sorry for being born.

Chapter Text

“Mommy, stop!”

A crash echoes against the walls of the house that Izuku refuses to call home.

“You’re always causing problems for me, Izuku! First, I get pregnant with you, then you make me the laughingstock in front of my friends with your quirklessness and now you make a mess of my kitchen! I should’ve gotten rid of you when I had the chance.”

The little freckled boy stares at his mother with blurry eyes. He just wanted something to drink. Mommy wasn’t home, so he went and grabbed some himself, but he was too short and accidentally dropped the cup. It shattered over the wooden floor with a deafening sound, way too loud for the quiet house.

“Oh no, oh no no no, mommy is going to be so mad.” Izuku knelt down on the floor and tried to scoop the glass up with his bare hands, crying out as glass cut his hands. Standing up again, blood dripping onto the floor, he turns to go to the tap when the door opens. Izuku freezes.

“I’m home.” Is being called from the foyer where Inko was taking her shoes off. “Izuku, where are you? In your room?”

Izuku is panicking now. What should he do? Mommy is going to be so mad.

‘What do I do?’

“Izuku?” Inko’s voice calls from the kitchen entrance, “what did you do?”

“I-I-I’m s-sorry m-m-mommy.” He stuttered as he took a step back on unstable feet, almost stepping in the glass. “I-I just want-”

SLAP

Izuku cries out as he falls on the glass, pain blooming in his hip and hands as the glass cuts through his skin.

“What did I say about causing me problems. You always find a way to make me regret having you. Now clean this up, and I swear if I hear so much as a peep from you, you will stay in your room for a week.”

The little boy scoops up the shattered glass again and he has to bite his tongue to hold in the whimper he wants to let out from the cuts in his hands. Swallowing, he grimaces at the iron taste. Izuku brings his hand to his mouth and lets out a choked sob when there comes blood from his mouth.

Before he can continue cleaning the glass, he lets out a yelp when he is grabbed by his hair.

“I thought I warned you if I heard something. Guess I need to lock you up for two weeks now.” The woman sneers in Izuku’s face while she holds him up by his hair. Izuku is kicking and trying to make her let go when she starts walking to his room.

“Mommy, stop!” kicking and screaming he tries to make her let him go. A crash echoes against the walls of the house that Izuku refuses to call home. Izuku screams as he slams against a vase in the living room where Inko had thrown him.

“you’re always causing problems for me, Izuku! First, I get pregnant with you, then you make me the laughingstock in front of my friends with your quirklessness and now you make a mess of my kitchen! I should’ve gotten rid of you when I had the chance.”

The little freckled boy stares at his mother with blurry eyes.

“I-I’m sorry m-m-mommy.” He stutters as he is being picked up again but this time, he doesn’t fight back. When they get to his room, he gets thrown on the floor where he stays for the next 2 weeks after the door slams shut. When he hears the locks turn and footsteps going away and downstairs. He doesn’t cry. He doesn’t scream. He doesn’t beg. He just lies there, on the cold hardwood floor. A thought passes his mind, and something shifts within him.

‘I’m sorry for being born.’

He was never locked up again.


Izuku sits up with a start with tears streaming down his face and his breathing erratic. After calming his heart down a little, he goes to his desk to write everything down in his notebook.

When he started therapy two weeks ago, Hound Dog told him that whenever he remembers something from his past, he had to write it down. Before tonight he didn’t remember a lot, other than what he already told some people, so the notebook is still empty.

He was skeptical about remembering stuff about his past and started losing hope that he wouldn’t ever remember things. Hound Dog was adamant though that he would if he let it. That was yesterday.

As he’s writing, he hears a grunt behind him. Izuku turns around and sees Kacchan looking at him through sleepy eyes, still half asleep.

“‘Zuku? Whut, ya doin’?”

The freckled boy smiles fondly at his mate and gets up to sit on the bed next to the blonde. “I was just writing some things down for therapy. I told you about it.”

Kacchan rolls over with a groan on his stomach and throws his arm over Izuku’s waist, burying his face in Izuku’s thigh. The shorter male puts his hand in the blonde spikes and starts scratching his scalp lightly to lull him back to sleep. “Mkay. Come back soon?”

“Of course, baby. I always come back.” He gets a grunt in return and when he’s sure Kacchan is asleep, he carefully gets up to continue his writing. He was almost done so it doesn’t take long to finish. After closing his notebook, he gets up and joins kacchan back in bed. The Alpha grumbles in his sleep but subconsciously throws an arm over the Omega and buries his face in the crook of his neck.

Izuku rakes his fingers through Kacchan’s hair and falls asleep shortly after.


In the morning, Izuku sends hound dog a text message saying that something happened last night and needs to see him. He gets a text after breakfast where Hound Dog says that he can see him after school and to bring his notebook.

While they’re walking to class Kacchan pulls him aside and cups Izuku’s cheeks with his hands. He puts his hands on Kacchan’s hips in concern. “Kacchan? Something wrong?”

“No, just wanted to check up on you after last night. You looked pretty shaken up and your eyes were fucking red.” He says with a rough but soft voice.

Izuku feels his heart swell with the way kacchan cares for him. “I’m okay, Kacchan. Just remembered something and Hound Dog told me to write it down. I already told him about it and I’m going to see him after school.”

Crimson eyes look into emeralds with concern, so Izuku puts his arms around Kacchan’s neck and leans up to kiss the blonde in reassurance. Strong arms wrap around his waist and he melts. Izuku leans back and stares into the eyes that he loves so much while playing with the short hairs on his nape. “Okay ‘Zuku, if you’re sure. You know you can talk to me, right?”

“I know Kacchan, and I will once Hound Dog considers me ready. I don’t want to hide things from you, but I trust him to tell me as soon as I am ready to tell you everything.” He looks away. “I-I hope that Kacchan trusts me enough to wait.”

Kacchan grabs his chin lightly to make him look at him again. “You know I trust you baby. And you always tell me everything. Even if you can’t tell me this yet, I’m glad that you can trust Hound Dog to tell you when you’re ready. And you always tell me that you’ll tell me everything in due time. So yes Izuku, I trust you. Besides, you’ve never hidden anything and almost immediately told me what Hound Dog told you the first time you had therapy. Even if it takes 10 years, I want you to be ready.”

During his speech, Izuku started tearing up and smiling so hard his cheeks hurt. The Omega jumps up and buries his face in his Alphas neck while Kacchan chuckles at his mate’s antics, catching him by his ass easily. “I-I love you, Kacchan!”

They never went further in the sex department than making out and heavily grinding on each other. They didn’t even have sex when they mated. Sure, they’ve seen each other naked but never indulged in their desires since izuku spoke up about his insecurities when they first got together. They’ve always been touchy with each other so there was no reason to get comfortable with each other since they always have been. Whether it be on more intimate places or just leaning against each other.

Regularly izuku checks up with his Alpha to make sure he’s still okay with not having sex and every time Kacchan shuts him up with a kiss that gradually gets more heated up as they get lost in each other from the sensations. Kacchan won’t answer him until they both came in their pants.

After they’ve calmed down from their orgasm’s he’ll look his Omega directly in his eye and tells him with a stern but soft and oh so reassuring tone, ‘If that doesn’t prove anything, I don’t know what will. We communicate everything. If we can be better than any fucking relationship out there, than it’s damn well easy to not be some fucking knothead Alpha.’

The blonde hugs him just as tight, burying his face in the green curls. “I love you too sweetheart. So much.”

Izuku pulls back a little to look at Kacchan asking, “Always?”

“And forever.” Kacchan finishes, smiling.

Leaning forward, they kiss again before Kacchan puts him down so they can head to class.
