Not proofread. Go easy on me <3
You yawned, scratching your bedhead, as you walked into the kitchen to see your husband, Katsuki, already making breakfast. You walked up to him, wrapping your arms around his waist, "Good morning.~"
"Mornin', beautiful," He replied, flipping a pancake onto a plate. It was fluffy, just the way you and Mizuki liked it. He turned around and pressed a kiss to your lips. Your good morning kiss. You smiled, pecking his cheek.
You took the plates with the pancakes out into the dining room, Katsuki following behind, holding a tray with cups of coffee. You put the dishes on the table and opened your mouth to call your seventeen-year-old daughter down for dinner but stopped when she entered the kitchen, hopping on one foot as she put on her socks.
You raised your eyebrows in amusement. Surprisingly, Mizuki had been waking up early for a few weeks now. Previously, you had to turn off all her alarms for her and aggressively shake her awake.
"Morning, mama, papa." She greeted as she pulled her long blonde hair into a ponytail, crimson eyes shifting up to you and Katsuki.
"Someone's wakin' up surprisingly early." Bakugo commented, "Now come on, food's runnin' cold."
"Oh. I have to be at school early today." Mizuki took her school bag from a chair, throwing it over her shoulder. Bakugo furrowed his eyebrows, watching his daughter run out of the room in a hurry.
"Oi, get yer ass back here! You ain't leaving without breakfast!" He yelled, his head snapping at you, asking you to say something. You shook your head, raising your hands up. Only a Bakugo could tame a Bakugo.
"I'll get somethin' from outside, chill!" Mizuki yelled from the front door.
Bakugo looked at you, baffled, "She's got the time to eat from out but not to eat from home?!"
"Maybe she's not in the mood for pancakes." You replied, taking a seat at the dining table, pulling a plate towards yourself, and pushing another towards Katsuki.
You smiled, watching him pout as he chewed. He was just like the Katsuki you met in high school, yet he was so different. His muscular arms and torso were littered with little scars, with one big scar on his chest. It was proof of years of hero work. His hair was slowly starting to grey. When he put his head in your lap, you liked moving his hair around, counting the little grey hair.
"D'you think she doesn't like my cooking?" Bakugo asked.
"You know that's not the case, Katsuki." You give him a pointed look, "You don't have to be upset about it."
"I'm not upset..." He huffed. You sighed, smiling at him. He clearly was upset. You were going to add that she might have met a special someone, so that could be one reason why she was in such a hurry, but decided to keep it to yourself since you knew the reaction your husband would have. He'd flip the table over.
"What if she's seein' someone?" He narrowed his eyes, his fist clenching on the table. You reached over, putting your hand over his closed fist. His hand relaxed, lying flat underneath yours.
"It's possible. She's growing up, it's expected."
"I'm sure she's got better things to do than bothering with some lame-ass guy." He confidently shoved a piece of pancake in his mouth. A drop of sweat appeared on your forehead at his sudden change in demeanour.
Katsuki's suspicions of Mizuki going out with someone did not stop there.
He'd just come home from patrol, sweaty and tired, hoping to take a nice long bath and then eat dinner and spend some time with his two favourite girls. He stepped inside the house, kicking his dirty boots off and padding into the living room.
He found you on the couch, your face lighting up when you saw him. You hopped off the couch to give him a fat kiss on the cheek, "Hi, babe. How was work?"
You laughed, wiping a bit of grease from his cheek with a thumb, "I've already run the bath for you."
You caught a naughty glint in his eye when he turned you around, hugging you from the back, his chin on your head, stubble scratching your scalp, "Join me."
"Mizuki's home, Katsuki." You rolled your eyes.
"It's just a bath." He teased.
You stepped away from him, giving his chest a playful push, "We both know it will end up being not just a bath."
"Mama!" Mizuki rushed into the living room, holding a hairbrush in hand, wearing a pretty blue dress you got her a while back, "Mama, can you do my hair?" Her eyes fell on Bakugo standing behind you, brow arched skywards. She visibly froze.
"Where are you going?" He asked, noting how she was dressed a little nicer than usual.
"With friends, duh," Mizuki replied, handing you the hairbrush. You brushed her hair, putting up into a neat bun for her.
"Oi, don't forget to leave your location on and-" Bakugo began but got cut off by Mizuki.
"And don't forget to be home before ten, blah, blah, blah. I know. You need to stop worryin', Pops." Mizuki looked up at her father as she put her heels on.
"I'd stop worrying if you weren't dressed like you're going on a damn date," Bakugo said.
Mizuki cleared her throat, rolling her eyes. "Well, I'm not. Can I leave now?"
Bakugo moved aside, letting her leave, eyes not moving from the door until it was slammed shut. "I'm tellin' ya, she's seein' someone. And I'm fuckin' finding out who it is-" He made a move to leave after her, stopping when you put a hand on his arm.
"Let her go, Katsuki. If she finds out you're stalking her, she's not going to trust you with anything."
"You wouldn't want her sneaking out and lying to you, would you?"
"Exactly. Now go hop in the bath, stinky." You smacked his arm. He gave you a devilish smirk and threw you over his shoulder.
"You're gettin' in with me. Mizu isn't home now."
It was the weekend, and you were out doing groceries with Katsuki. You watched your items get scanned at the counter, making sure you guys had everything you needed. You reached to carry some of the grocery bags, getting your hand slapped away by Katsuki. He carried them all in one go, his muscles flexing in the process.
Before going back home, he got Mizuki iced tea since he knew she liked it. He parked the car in the garage, helping you carry the grocery bags inside.
"That's the last of it." He grunted, dropping a bag on the floor by the shoes.
"I'll go ask Mizuki to help me put stuff in the fridge." You said, removing your shoes. You went into the living room, freezing when you saw Mizuki sound asleep on top of a boy you recognised. Kyoka and Denki's son, Ryuu. He had plum-coloured hair, just like Kyoka.
"Oi, Mizuki, come help ya ma with the groceries," Katsuki yelled, walking into the living room. He saw you standing by the couch and came to stand beside you, looking down to see Mizuki asleep with her head on Ryuu's chest. His yelling made Mizuki stir a little before she nuzzled into his neck and went back to sleep.
You glanced at Bakugo, watching his jaw clench, his upper lip twitch in fury. You could swear you saw steam blowing out of his ears. Before you could stop him, he stomped up to the two, "WAKE THE FUCK UP!" He yelled.
Startled, Mizuki sat up upright, falling off the couch. Ryuu opened his eyes wide in confusion. He looked down at Mizuki and then at Dynamight towering over him with deadly crimson eyes that promised to skin him alive. Ryuu gulped, his face draining of colour.
Katsuki grabbed the boy's T-shirt, pulling him off the couch. Ryuu raised his hands defensively, trying to step away, but Katsuki had a death grip on his T-shirt, "Who the fuck do you think you are?!"
"Dad, leave him alone!" Mizuki tried pushing Katsuki's hand away. Katsuki ignored her, simply pulling Ryuu closer and narrowing his eyes at him.
"What is your relationship with him, Mizuki?" He growled, still not looking at her, giving Ryuu a death glare instead.
"Katsuki, leave him alone. How about we all sit and talk about it calmly-"
"I ain't talkin' calmly!" Bakugo yelled, scaring Ryuu. "Who the fuck does he think he is, trying to snuggle into Mizuki?!"
"Dad, can you please stop?!" Mizuki gave her father a firm push. The push had little impact on him, given he was built like a tree, but the flash of hurt in his eyes did not go unnoticed by you. Mizuki freed Ryuu out of Katsuki's grip, standing in front of him almost protectively, her hand intertwined with his. "As for your question, he is my boyfriend. What are you going to do about it?"
"Really, Mizuki. You're fuckin' joking." He glowered at Ryuu, his fists fuming, "You ain't datin' spark plug's son."
"Why do you have a problem with everything I do?!" Mizuki yelled, "I'm not a little girl anymore, Dad! You don't get to decide who I date and who I don't."
"You don't need to date some stupid boy. You know you're better than that!"
"Ryuu is not a stupid boy." Mizuki seethed through gritted teeth. She looked like she'd blast the house to bits if Katsuki said another word.
"I-I'll take my leave so you guys can talk. I'm sorry for the trouble I caused..." Ryuu dared to pat Mizuki's shoulder and glance up timidly at Katsuki. Katsuki took a step towards him but got stopped by your arm.
"You're breaking up with him right fucking now," Katsuki ordered.
"I am not!" Mizuki shouted, taking Ryuu's hand again, making him stay put. "What has he ever done to you?! Why do you have to act like he committed some crime? Ryuu is the most perfect and sweetest person I've met, unlike you. Why do you have a problem with everything?! When will you leave me be and stop pretending im five?! Gosh, I really fucking hate you."
Mizuki's chest moved up and down, tears threatening to spill from her eyes, staring at Katsuki, the air thick in between them. She glanced at you before she turned around with Ryuu, silently leaving the house with him.
Katsuki fell onto the couch, head thrown back, hand over his eyes. You silently sat beside him, putting a hand on his knee. He glanced down at his legs, a defeated look on his face. You cupped his cheek, making him look at you in the eye. You could see tears forming in his eyes, his nose red.
"She said she hates me." His voice cracked.
"Shh," you brought his face closer, kissing his eyebrow. "You know she doesn't mean it. She said it in the heat of the moment."
He let himself lay on top of you, nuzzling into your neck, arms wrapped around you. He wondered if this was karma for all the times he told his mother he hated her even though he didn't really mean it. He wondered if this was life slapping him in the face, pulling a reverse card on him.
"You remember how old we were when we started dating, Katsuki?" You asked, running hour fingers in his hair.
"Hm. Mizu's way older and more mature than we were back then."
"She's mature. Spark Plug's kid isn't" He propped up on his elbow, arguing back with you.
"Are you doing this because he's Denki's kid? He's a good kid, Katsuki. He didn't even argue back when you got mad at him. He's rational, and from what I've seen when Mizu brings her friends over, he's really shy and sweet, too."
"What if he's not good enough for her. What if he breaks her heart?" He tried reasoning. You smiled, cradling his face.
"She's got her big strong papa if he breaks her heart."
His head dipped low, pressing a long kiss onto your lips and then a little one in between your eyebrows. You switched positions, with you now lying on top of him, head on his chest, eyes shut. He kissed your hair, hand running up and down your back, deep in thought.
As he lay there, he thought of the time when he held newborn Mizuki in his arms for the first time, immediately falling in love with his little girl. The moment Mizuki was in his arms, he swore he would protect his daughter with his life. He recalled her first footsteps and her first word, 'Da!' He thought of the time when she got her quirk, running into his legs, crying, overwhelmed by the loud noises and the recoil.
He sighed, eyes drifting shut.
When Katsuki's eyes snapped open, it was already midnight. He felt a blanket over you two. Mizuki was home. He skillfully slipped his arm out from under your head, getting up. He adjusted the blanket over you, kissing the tip of your nose. Light on his feet, he went upstairs, standing outside Mizuki's room.
He cleared his throat, knocking on the door, "Hey, kid. Ya in there?"
He was greeted by silence. He turned the knob, opening the door and peeking inside. There she was, lying with her back to the door, pretending to be asleep, blonde eyelashes fluttering on her cheeks. He crept up to her bed, taking a seat on the mattress, the bed sinking down with his weight.
He leaned over, tucking a few strands of hair behind her ear. He put his forehead on her head, "I'm sorry, Mizu. I know I was an ass." He murmured.
Mizuki lay on her back, crimson eyes shifting to her father. His eyes, the same colour as hers, almost pleaded with her to talk to him. She sat up straight, putting a hand behind her neck, looking down.
"It's alright... I'm sorry, too. I didn't mean anything I said back then." She felt her father's arms wrap around her shoulders, pulling her closer. In his strong arms, she felt safe. Even though they often fought and argued, she adored him. He meant the world to her.
"I'll break up with him." She said.
Katsuki pulled away from the hug, shaking his head and taking her hands, "No. If he makes you happy, you can date him."
"What's the point if you're not happy about it?"
"I'll be happy about it as long as he keeps you happy." He held her face in his hands, looking into her eyes, "But the moment he breaks your heart, I'm breaking his legs, and you're not stopping me."
He watched a shit-eating grin take over her face, scarily looking like him, "If it ever comes to that, I'll join you."
"Atta girl." He smirked. Mizuki threw her arms around his neck, hugging him tight. Katsuki smiled, holding his daughter closer.
"I love you, papa." She mumbled.
Katsuki held himself from crying right there and then, "Love ya too, Mizu."
Katsuki held Mizuki for a while longer, enjoying this rare moment of peace with his daughter, running his hand through her long hair. He felt a pair of eyes on him and glanced back to see you leaning against the doorframe, arms crossed across your chest, a soft smile on your face. He held an arm open for you to join him and Mizuki.
You crawled into bed, kissing Mizuki's cheek and then Katsuki's jaw. He pulled your head on his shoulder, his arms wrapped around you two.
While you and Mizuki slept peacefully, Katsuki stayed awake, his heart brimming with love and bliss. Lying on the bed with his world in his arms, he wondered what he did to deserve you two. He considered himself the world's luckiest man.
