The first time Kirishima visited the Bakugou household as a friend, Bakugou Mitsuki had no mercy on him.
She opened the front door, and immediately shrieked upon seeing him.
“What are you, bringing home kids from the circus now?” She yelled, directing her glare at Bakugou.
Kirishima stood there, frowning as he suddenly felt very naked. Must be a Bakugou thing.
“He’s not a circus clown, he’s just a walking fashion disaster!” Bakugou replied, shoving past her. “Also stop yelling, old hag! This is why I don’t bring anyone home.”
Mitsuki looked at Kirishima for a few seconds before moving to the side to let him in. He smiled, despite his confidence struggling to keep its head above water. She must not have remembered meeting him prior. They didn’t interact much, so he was quick to forgive her.
“You don’t bring anyone home because you don’t have any friends, you little rat.” Mitsuki argued back as she walked away. Kirishima watched as she stopped by Bakugou’s father along the way, squeezed his shoulder then left the room. Masaru perked up from the corner of the room where he was cleaning, looking from Kirishima to Bakugou before smiling politely.
Bakugou didn’t give him much of a chance to say anything, dragging Kirishima away to his room.
By the end of the day, Bakugou all but pushed him out of the house before his parents could see him again.
The second time he visited as Bakugou’s friend, Mitsuki dunked Bakugou’s head down as soon as she opened the door.
“Join us for dinner, whatever your name is!” She shouted, ignoring Bakugou’s flailing limbs and string of swears.
“K-Kirishima Eijirou,” He replied with a slight bow, not wanting to be rude, “And I’d love to!” To be honest, he was absolutely terrified of how dinner would end up. Eating with Bakugou was already like testing his fate with a time bomb, but two of them? That was, of course, assuming Masaru didn’t also have a secret temper.
Mitsuki ordered Bakugou to cook with her that evening, and surprisingly Bakugou didn’t argue much. Kirishima watched the two chop away at vegetables like it was a race. He was only a little worried they’d end up cutting themselves. He was pretty sure any injury they did manage to get, would disappear purely from sheer rage.
Masaru settled down next to him on the living room couch, giving him a curt nod. They sat in silence for a bit, the sounds of knives against wood filling the air. Masaru turned to him at some point, eyes analyzing his face before smiling sweetly.
“They’re wonderful, aren’t they?” He asked, hands on his knees as he leaned forward.
“That’s one way to put it,” Kirishima chuckled, eyes cast to the side.
Masaru didn’t say anything for a moment.
“How do you feel about Katsuki?” He tilted his head slightly.
Kirishima’s eyes widened, his stuttering heart thumping loudly in his chest. He took a deep breath, “Bakugou is a really passionate guy. He kind of scared me at first, but that changed quickly. He’s an amazing friend, and I don’t think anyone in the world could ever replace him.”
Masaru caught his gaze, and Kirishima swallowed thickly. Then Masaru grinned.
“I know exactly what you mean,” he looked away, back to the kitchen. His expression was so soft as he stared at Mitsuki and Bakugou, Kirishima felt like he was invading on a private moment. “I wouldn’t trade them for the world.”
“Even with all the yelling?” Kirishima snickered.
Masaru laughed, hand on his stomach. “You get used to it.”
Kirishima nodded, “I know.”
When dinner came around, it was about as chaotic as Kirishima thought it would be.
Bakugou sat down and immediately brought his bowl up to his mouth. Mitsuki smacked the back of his head, telling him to take a moment to be grateful for the food. Bakugou yelled at her, something about how she should be grateful she didn’t show the wrinkles she no doubt had. That evolved into Mitsuku pinching his cheeks like he was a stretchy toy, and Bakugou threatening to blow the whole table away.
Kirishima and Masaru sat across from them, silently staring. Masaru wore a slightly pained expression, a drop a sweat making its way down his temple. Kirishima lifted his bowl up just in case Bakugou went through with his word.
Luckily, by the end of it, they were able to eat without their food ending up across the room.
When he left, Mitsuki and Masaru waved. Bakugou didn’t look at him, but he did slightly raise his hand. Kirishima figured that was the best as he was going to get.
The third time Kirishima visited as Bakugou’s friend, he and Bakugou had plans to watch hero documentaries. He had originally planned to watch them with Midoriya, but as soon as he brought up the idea to Bakugou, the boy all but demanded they watch them together instead. Kirishima didn’t argue, the new plan sounded even better than his initial one.
They lounged around on the couch, going through multiple documentaries spanning several heroes. Kirishima, of course, brought one about Crimson Riot, while Bakugou subtly suggested an All Might one. The rest were of lesser known, but just as cool heroes from the last few decades.
At some point, Bakugou must have fallen asleep on his shoulder. Kirishima was half-asleep himself, head leaning on Bakugou’s as he struggled to keep his eyes open. They were in the middle of a film about how heroes were portrayed before quirks existed, and comparing them to the pro heroes of the modern day.
He turned his head away to yawn, only to choke mid-action. He blinked at Mitsuki who was standing off to the side, arms crossed over her chest while she leaned on the wall gazing at them. She lifted a finger up to her lips, a sign to stay quiet.
Kirishima nodded, heart swelling at the feel of Bakugou’s hair tickling his face. He tried to nuzzle closer in a discreet manner, but the way Mitsuki snorted in the distance told him he failed. He was too tired to care.
He shifted, wrapping an arm around Bakugou as he leaned backwards. Kirishima didn’t really feel like waking up with a sore neck. Bakugou grumbled a bit, but nonetheless settled on Kirishima’s chest.
He was nearly asleep again when quiet footsteps caused him to open one eye. He felt something warm and soft cover them both, a blur of pink clothes and blonde hair moving around. A hand pat his head, then ruffled Bakugou’s hair.
Sleep took him away before he could think about it too hard.
The fourth time Kirishima visited as Bakugou’s friend, Bakugou was in a very touchy mood.
They sat on the couch, and Bakugou’s hands were pinching his cheeks. He whined as they were tugged on, moved up and down and squished as if his face had the stretchiness of a Shiba Inu’s.
“Dude,” he whined, but Bakugou ignored him, smacking both of Kirishima’s cheeks together. Kirishima had the sudden urge to call himself an idiot sandwich.
He heard a snicker off the to side, and when he looked both Mitsuki and Masaru were peeking their heads around the doorway to the room. Bakugou let go of his cheeks, bless, and fired a glare at them.
“What the fuck are you two doing?” He called out, to which they both grinned.
“I remember the first time your mother made my cheeks her new toy,” Masaru commented, eyes distant and fond.
Mitsuki smirked, “I remember the other time I made your cheeks mine.”
Bakugou screeched, and Kirishima wanted to crawl into a hole.
“You two are so fucking embarrassing!” Bakugou yelled, throwing one of the pillows on the couch at them.
Mitsuki caught it easily and threw it back twice as hard, smacking Bakugou in the face. Kirishima covered his mouth with both hands to contain his laughter.
“Stop encouraging her!” Bakugou’s fingers twitched. Hell, his whole body twitched.
Kirishima grinned at him, shrugging. “What can I say? It’s nice to see someone who can actually put up a fight against you.”
Bakugou narrowed his eyes at him, but he knew the boy would take the bait. The only match for Bakugou, was another Bakugou.
Kirishima stood up to pull Bakugou back to the couch. As soon as his hands touched Bakugou’s arms, the boy relaxed, allowing himself to be moved. Kirishima plopped back down, Bakugou on his lap. He reveled at the sight of Bakugou’s cheeks turning pink.
“You’re annoying,” Bakugou muttered, giving his cheeks a particularly hard squeeze.
Kirishima pouted, “I didn’t do anything.”
“Doesn’t matter,” Bakugou countered, letting his full body weight sink onto Kirishima’s.
“Remind you of anyone?” A voice startled them. Masaru hummed. They somehow managed to forget Bakugou’s parents were still there.
“Way too much,” Mitsuki answered, pulling her husband away as another pillow flew by their heads. Though he didn’t move, Kirishima was reminded of just how colorful Bakugou’s insults were.
The fifth and last time he visited as Bakugou’s friend, he wanted advice.
He knew what he wanted, and he could probably trust himself to pull it off had it been any other person, but it wasn’t just any person. It was Bakugou. So he went to the only people who he knew could help.
When Mitsuki opened the door, she looked reasonably surprised. She glanced around for a moment before smiling at him, brows still raised.
“Hey Eijirou! This is a pleasant surprise. Where’s Katsuki?”
He shrugged, “I ran here faster than he could?”
That caught her attention, and she tugged him inside. She had a big scary grin on her face. “Secret?”
He nodded, teeth nibbling on his bottom lip. He cleared his throat, “How did Masaru-san ask you out?”
Mitsuki blinked, once, twice, and then turned around with her hands cupped over her mouth. “Masaru get the hell over here! You owe me money!”
Masaru stumbled in, glasses askew. “Did he-?”
Mitsuki beamed, nodding. “Our angry kitten of a child managed to get someone as nice as Eijirou here to like him!”
Kirishima buried his face in his hands, groaning. This had been a mistake.
Mitsuki grabbed his arm and rushed them away, into a room with a big mirror. She made him sit down in a chair facing the mirror as she ran her fingers through his hair.
“Well first of all, let’s make you look good. Don’t get me wrong, you’re as cute as a button, but I want your face to tell my son you mean business.” Mitsuki started combing his hair. Kirishima winced as all of his hard work from that morning went to waste.
Masaru stepped behind them, eyes crinkled in his reflection. “If he’s anything like Mitsuki, then he’ll try and treat a date like a challenge.” He slipped an arm around her waist, but she batted him away.
“Be mushy later, this boy needs an emergency makeover. Katsuki could be here at any-”
“I’m home!” A voice made all three of them jump.
“Aw, crap.” Mitsuki pointed at the door, “Distract him, my dearest lover.”
“Your only lover,” Masaru snorted as he walked away. Mitsuki let out a heavy sigh.
“I fucking love that man,” she kept gazing dreamily at the door before Kirishima coughed. “Oh, right, let’s do this.”
The experience could best be described as trying to wash and brush a dog whose fur has several pounds of gel in it. All in all, not pleasant.
By the time Mitsuki was done ravaging his hair and decorating his face, Masaru was entering the room once again, looking worse for wear. Being the father of Bakugou, Kirishima wouldn’t be surprised if that was his default appearance.
“He’s in the living room doing homework,” Masaru sighed, rolling his shoulders back.
“You’re so brave,” Mitsuki beamed before shoving Kirishima forward. “Look at him!”
Masaru perked up slightly, nodding his approval.
Kirishima glanced at his reflection and nearly tripped over his own feet. His hair was styled into some kind of fancy bun. It was manly in its own way.
“Isn’t this a bit much?” He asked.
Masaru shook his head, “Mitsuki made me redress myself three times before she agreed to go on a date.”
“I just enjoyed teasing you to see if you’d do it,” Mitsuki admitted, pushing Kirishima forward and out the door. She leaned down to whisper into his ear, “And he did. He was so whipped.”
Kirishima couldn’t help the small laugh that escaped him, despite his nerves yelling at him to run away. Mitsuki kept pushing him until they were back in the living room. Kirishima froze, the hands on his shoulders failing to make him go any further.
Bakugou was on the couch, pencil behind his ear as he flipped through his textbook. He looked up when they came in, eyes widening just a fraction before he schooled his expression into his default scowl. “What the fuck?”
“Hey,” Kirishima tried for a smile, but he was sure it came out more like a grimace.
“What did you do to him?” Bakugou stood up, taking a step towards him. “He looks…”
“Handsome?” Masaru offered.
“Beautiful?” Mitsuki leaned forward.
“Stupid,” Bakugou settled on, causing Kirishima to deflate. He couldn’t bring himself to swallow around the lump in his throat.
“Be nice, you brat!” Mitsuki shouted, grip on his shoulders tightening. Kirishima’s fingers twitched. She was stronger than she looked. “You should be happy anyone would take the time to doll themselves up for your ungrateful ass!”
“Why?” Bakugou frowned, gaze meeting Kirishima’s.
Kirishima took a deep breath before marching right into Bakugou’s personal space. The boy didn’t back up, meeting Kirishima face on.
“Bro- Katsuki,” Kirishima looked right into his eyes, pleased with the small inhale he heard, “you can be such a dick sometimes, but I really like you. You’re strong, and you’re so damn cool. I’ve never met a guy who wanted to succeed as much as you do. You’re the manliest guy I know! Will you go out with me?”
Silence. Masaru’s words ringed in his head.
“Unless you’re a coward,” Kirishima added, watching Bakugou’s face split into a smirk.
“Okay fine,” his eyes narrowed dangerously, “date me then, fucker. Date me as hard as you can.”
Someone cleared their throat from behind them, “Well, you two have fun. We’ll be… anywhere else.” Masaru announced.
Kirishima turned his head in time to see Masaru lifting Mitsuki up into his arms as she flailed.
“I wanna watch! Put me down! If I don’t witness this legendary event I’ll never believe myself tomorrow!” She kept yelling at she was carried away.
“She’s such a creepy old hag,” Bakugou muttered, bringing Kirishima’s attention back to him.
They kept eye contact, and then Kirishima was giving Bakugou the most smug smile of his life.
“Bet you can’t kiss better than me,” Kirishima declared, and before he could say anything else, Bakugou was pushing him onto the couch and smashing their mouths together.
As it turned out, they were both pretty horrible.
Even so, Kirishima wouldn’t have had it any other way.
The first time Kirishima visited the Bakugou household as Katsuki’s boyfriend, Mitsuki and Masaru welcomed him with open arms.
