Chapter Text
Honestly? Muichiro could just buy Genya anything he wanted for his birthday and be done with it.
But no, because what kind of boyfriend is he if he’s just going to gift him some manufactured shit lovelessly made by an overworked person who probably missed their own kid’s birthday?
He wants it to be special. Muichiro wants his gift to come from his own blood, sweat, and tears because he loves Genya that much.
But what would he make him, a card?
“Sure. With those little pop-up hearts and my glittery vomit to go along with it because that’s so fucking gross.” His twin, Yuichiro, helpfully suggested.
Hmm. Muichiro has no artistic or crafty skills but perhaps he could knit Genya something, like a scarf?
Yuichiro scoffed. “Cliche. Plus, you know what happened to Taylor Swift and her ex who kept her scarf, right? He kept smelling it like some sweat-fetished freak.”
“You listen to Taylor Swift, Yui?”
“No. I just hate how romanticized that song is. Keeping her scarf from the first week they met because it still smells like her? After all those years? More like it smells like his drawer full of unwashed, crusty socks.”
Muichiro’s face lit up. He snapped his fingers. “That’s it, Yui! I’ll knit Genya socks! It’s smaller than a scarf and shouldn’t take more time.”
Yuichiro cackled. “What time? His birthday’s today, did you forget? Moron.”
Oh shit, that’s today?! Well technically, Muichiro did not forget the date, he just forgot what day is it.
“Shit, Yui. What do I do?!” He panicked.
“Just go to the nearest konbini and buy him a dumpling or a bar of chocolate, what’s the fuss?” Yuichiro waved his concern away.
Muichiro stomped his foot, “No! The gift must come from me!”
“For fuck’s sake, Muichiro!” Yuichiro rolled his eyes at his drama queen of a twin. “Makeout with him for three hours or whatever! Just make sure to use atleast two bottles of mouthwash before you talk to me again.” Yuichiro huffed as he stood up but felt his twin tug pitifully at his arm.
“Yui, help me, please.” Muichiro pleaded, his chin quivering, his teal eyes wide and shimmering with unshed tears. Ten years ago, it was his way of coercing him to play but now it’s his way of asking for a favor for his boyfriend’s sake.
“Whatever happened to your ‘own blood, sweat, and tears’? “
“Just help me with what to do, I’ll do it on my own.” Muichiro sniffled. Fake sniffled. Yuichiro clicked his tongue in annoyance.
“You know how you can burn rice?”
“Yeah?”
“Why not try burning him a cake?”
So with the speed of a lightning, Muichiro biked to the nearest store. He had decided on a simple vanilla chiffon cake with buttercream icing.
It was only when Yuichiro had welcomed him back home when he realized that their stove’s one of those that doesn’t come with an oven.
Because they sometimes share the same wavelength, Yuichiro’s struck with this thought too. He suddenly sits upright from the couch, his head going back and forth between his twin and their useless stove.
“We can go to Michikatsu’s” The older twin shrugs. “He has an oven.”
“His oven’s like from Sengoku period.” Muichiro huffs. “There’s still probably some samurai’s toe in there.”
Opting to just steam the cake, Muichiro hurriedly lays out his ingredients. He’ll start with the icing first. Buttercream is easy enough. You can’t burn buttercream. Just a stick of unsalted butter, purple dye and icing sugar, Muichiro would’ve already completed the first step in no time.
“Yui, please tell me we have a hand mixer.”
“Nope.”
Sighing, Muichiro chucks the butter into a bowl to start creaming it. It would be slow and difficult but he would keep going until his arm fall off. Just what he wanted, right? Tears and sacrifice as a tribute to his most beloved pumpkin head.
Turns out, making a buttercream icing by hand isn’t that hard. All is actually going well. The food dye had incorporated well with the mixture, giving him a rich purple shade. Muichiro dips a finger in the bowl for a taste test. His face suddenly lights up.
“Yui, come here and have a taste!” He beckons his twin. Yuichiro grabs a spoon because he has dignity.
“It’s good, Muichiro. Genya doesn’t deserve you.” Muichiro shoos him back to the living room.
Inspired by his great success with the frosting, Muichiro got too confident with the cake batter. Who cares if they didn’t have a mixer? He would just whisk, whisk and mix by himself until the batter’s in the right consistency.
When the mixture’s liquid-y enough (No lumpy forms, which means he’s doing great!), Muichiro pads to the pot to carefully transfer the mixture into a cake tin placed above the boiling water. “There we go!” He checks his watch. “An hour and fifteen minutes until it’s done.”
His phone suddenly lets out a tune, that one special tune he had only reserved for Genya.
With a delighted gasp, he dashes to answer his call. He turns on the speaker.
“Hey, happy birthday Gen!” Muichiro giggles as he plops down beside his twin on the couch. Yuichiro hops away in disgust.
“You’ve been greeting me since morning but where’s my kiss?” Came the raspy voice from the other end.
“Don’t you dare, Muichiro or I’ll--” Yuichiro screeches but too late, his twin made a series of smooching noises at his phone and if it isn’t bad enough, Genya joined in too from the other side. At this point it wouldn’t be a surprise if they start moaning and tongue kissing their phones. “I hate my fucking life!” Yuichiro whines while he dramatically slides down a wall.
For a crazy long time. Muichiro and Genya chatted and giggled together on the phone as if they won’t be seeing each other later that night. Muichiro had already packed a bag. Yes, he’d be sleeping at Genya’s place, much to Yuichiro’s displeasure.
“And I have a surprise for you! I’ll go take care of it now, okay? I love you too. Can’t wait to see you!” Muichiro finally ends the call with an expression that looked like he just found out where eternal paradise is.
He saunters to the kitchen in high spirits, his slight sour mood has been fixed by a quick phone call with his bae.
Until he lifts the pot’s lid and discovers what monstrous form his cake had taken.
“Yuichiro! Yui! Help me!” He cries out. Atleast half of the batter has been cooked but the rest did not even bother to rise. If he would let it on for longer, who knows what might happen to the already cooked part? Shit. Fuck. It’s a disaster. What would he give Genya tonight?
“Oh no, Muichiro. Are you sure that the water’s already boiling when you put in the cake tin?”
“Yes, yes, I’m sure!” Muichiro’s on the verge of crying. An hour and a half until he has to leave and he would still need to decorate the damned thing.
“It’s probably because you mixed it wrong. Without a hand mixer, we couldn’t say if you did it too much or not enough.”
That did it. Knowing it’s his own fault, Muichiro let his tears run down his cheek. “B-but....but, but what do I do now, Yui?” He asks in frustration.
Yuichiro sighs before laying his hands on his twin’s shoulders. “Muichiro listen. Just be honest with him. Tell him you tried. And as much as I want vomit now because I have to say it, you know Genya loves you, right? What do you think he’d do? How do you think he’ll react?”
Muichiro sobs. “He’d still eat the entire thing.”
“I was hoping you’d say that he’ll understand anyway, but okay. Mui, if he really loves you enough to risk getting salmonella, then I’m sure he’d be happy if you just show up at his door wrapped in a bow.” Yuichiro cups his twin’s identical face to brush the tears away with his thumbs.
“T-thank you, Yui.”
“Go on, get dressed. I’ll finish up here.” Yuichiro pushes his twin towards the staircase. Things people do for love.
Genya’s party is on full-swing when Muichiro arrived. Said party consisted of Tanjiro, Nezuko, her piss-colored boyfriend, the stinky boar-smelling maniac, Ms. Tosscoin and her friend with dual pigtails.
They’re all gathered around the dining table, waiting for Genya to unbox the squad’s birthday present for him. Which turned out to be.....cake.
But it’s not just any homemade, Pinterest fail cake. It came out of a Kamado Bakery box which is known for their exquisite pastries. It was a marvelous, two-layered cake designed with molded fondants detailing Genya’s life.
Like the numbers 01 and 07, a huge slice of watermelon (also fondant), a chibified head of their math teacher, Sanemi, a gun to symbolize him being in the Sharp Shooting Club, a small tree which is meant to be a bonsai and if Muichiro’s eyes are not deceiving him, there’s a fondant cut-out of him and Genya holding hands with a little heart between them.
Muichiro would’ve been squeeing too if not for the fact that he came bringing only a tupperware of buttercream icing wrapped in a fancy bow. Nonetheless, he felt a sudden rush of warmth and gratefulness towards the Kamado siblings for the sheer effort of making his boyfriend such a wonderful cake, making Genya very happy as a result.
Genya wraps an arm around his shoulders before dropping a kiss on his head. “It’s amazing, right, Mui? Look, you’re so cute!” His grazes a finger on the fondant Muichiro tenderly. “I promise I won’t eat you-- I mean, the icing version of you....” Genya’s words were drowned out by teasing howls and hoots from their friends.
“Are you sure we should be leaving them alone, Tanjiro?” Zenitsu calls out.
“Are you sure you want to see us sucking faces?” Muichiro fires back in a deadpan tone to which the others erupt with laughter. Genya’s face rapidly becomes hot from embarrassment, probably being the same color as the bright red watermelon of the fondant.
Chuckling, Tanjiro smiles at the couple. “Muichiro’s right, Zenitsu. Well, we best be off. Happy birthday, Genya! We’ll plan a day out soon but for now, enjoy each other’s company.”
Tanjiro bumps fist with Genya, followed by a pat on Muichiro’s head. Genya growls at him. The others said their goodbyes and greetings as they pass both of them. Inosuke actually stays behind for a while to pluck off the bonsai tree icing then pops it in his greedy mouth.
“Happy birthday, Genpo! Enjoy, Takitou!”
“Get outta here!” Genya kicks him squarely on his muscly ass. Inosuke freakin crawls on all fours to the door, cackling madly.
But when Genya closes the door, there’s a gentle smile on his face. He loves his friends and all but the one he loves more than anything is right here beside him and needed his attention. Badly.
“Genya.” Muichiro utters. He jumps up, wrapping his legs around his boyfriend’s thick waist.
“Mui.” Genya whispers, just as much lovingly as he holds the smaller boy’s thighs for support. Without another word, their lips crashed against each other’s for a hungry kiss.
Before things get too heated, though. Genya makes a beeline for the couch where he carefully laid his boyfriend, their lips not even parting as they change positions. Still, they needed air so the two reluctantly pull apart to catch their breaths.
“Mui.” Genya pants against Muichiro’s mouth. “I love this and frankly, I can’t wait for more but you said you have a surprise for me, baby?”
Muichiro’s eyes suddenly widen. Oh yeah. Oh shit. The tupperware is at the table, looking cheap and dirty beside the cake.
“I-it’s me! Surprise!” He lets out a nervous laugh. Genya frowns. Muichiro never does that.
“Mui?” He urges, caressing the younger’s cheek with the back of his hand. “You know you can trust me, right?”
Muichiro sighs, pushing his boyfriend off him so he could stand. “I-it’s just.....I’m sorry, love. B-but I tried.” Whipping out his phone, he showed Genya the failure of a cake inside the pot. “T-the only thing I was able to make....is that.” He stands up to grab the mediocre case of buttercream icing.
“Oh, Mui.” Genya’s eyes are soft. And full of love. “I will treasure this. I will treasure all the things you make for me. Now, come and get some toast, we’ll have a feast!”
“Icing? On? Toast?” Muichiro was horrified.
“Why not?” Genya grabs a spoonful of buttercream before his face lights up like it’s Christmas. “Holy fuck, this tastes amazing! Marry me!”
And he didn’t know how but Muichiro started tearing up happy tears at that. Geez, the way this buffoon brings out emotions out of him....
“I mean when we grow up, a bit. Yeah.” Genya scratches the back of his head.
“Can’t wait.” Muichiro sniffles. “I love you.”
Genya puts back the tupperware on the table. “Come here.” He cups the back of Muichiro’s head. “God, Mui. I love you so much. I love you so fucking, fucking much, you have no idea. I don’t care if you gift me with a fucking spare tire or some shit, I will always be happy if it’s from you. Shit, I love you so much it makes me wanna cry.”
“Hey, don’t.” Muichiro lets out a watery laugh. It was his turn to cup Genya’s face so he could stare at his eyes. The most beautiful shade of purple. His buttercream icing could never. “I don’t want you crying on your toast.”
“Icing on toast? And a scary movie, what do you say?”
Muichiro grins. “I say, I can’t wait for cuddles.” He stands on his tippy toes, landing a kiss on top of Genya’s nose. Next time, he;ll just knit him socks and a scarf. “Happy birthday, Genya. Thank you for being born.”
