In the days when his father, the duke, calls for him, Izuku has no choice but to leave Kacchan alone in the shop.
He has been away from home for quite a while, and even though Izuku tries to runaway from his duties, he can’t really escape his father.
He has been away from home for quite a while, and even though Izuku tries to runaway from his duties, he can’t really escape his father.
He should just go back for a few hours, and make sure there’s a good number of people who see him, otherwise his father will send for someone to check up on him.
Or worse, his father himself can come here.
Or worse, his father himself can come here.
While Izuku can effortlessly explain the reasoning for all of his inventions, it will be difficult to explain why Kacchan has been living in the shop and why Izuku chooses to never leave him.
That's why he has no choice, but to heed his father's call.
That's why he has no choice, but to heed his father's call.
On the morning when Izuku leaves, he makes sure (and triple checks it) that everything is properly stocked for Kacchan.
The supply of medicine and food is enough for months, the heat radiator is rumbling away happily, there’s some gold and silver in the sheep coin back under the sink and –
“Deku, just go. Geez! You’re not going away for years and I can very much take care of myself!” Kacchan yanks his tie to bring him back to the present.
He's helping Izuku tie it because according to Kacchan, he ties it like he's a three year old.
He's helping Izuku tie it because according to Kacchan, he ties it like he's a three year old.
Once Kacchan is satisfied with his tie, he shoves Izuku out the back door, where the Midoriya carriage waits.
This is the first time that he’ll leave Kacchan alone since they met. What if something goes wrong?!

He doesn't know what is going with him, but before Izuku releases his hold on Kacchan’s hand, he doesn't give it a lot of thought and pulls Kacchan in for a tight hug.
His scarred hand cradles the back of Kacchan's neck, “Someone will come along every few hours to check on you.

His name is Aizawa. I trust him with my life, you can trust him too.” Izuku mumbles onto Kacchan’s shoulders.
Mmmm, he smells like the roses that Izuku bought for him and of Izuku’s soap (he likes that smell on him).
It’s hard to let him go.
“Fine.”

Kacchan manages to peel Izuku off, and holds him at arm's length. “Now go, you sappy nerd. Bring me more books, and make sure they’re exciting ones, okay?”
"Okay. Oh--wait! Kacchan I have something for you." Izuku pulls out a pair of small, rectangular devices from his pocket.
"Okay. Oh--wait! Kacchan I have something for you." Izuku pulls out a pair of small, rectangular devices from his pocket.
One is green and the other is orange. Both of them are small enough to fit his palm and there’s a small antenna protruding on one side.
It’s one of his inventions that he’s never had a chance to use in the field yet.
It’s one of his inventions that he’s never had a chance to use in the field yet.
Izuku spent hours yesterday on the balcony making sure it got enough juice for its solar powered battery.
“What is it?” Kacchan curiously takes the device and brings it closer to his eyes.
“What is it?” Kacchan curiously takes the device and brings it closer to his eyes.
“It allows us to talk with each other, even if I’m walking far away from you!” He pushes a button on the orange device and puts it close to his mouth to talk.
Then he holds the green device away with his other arm. “See, they transmit the sound the other makes, cool huh?”
Then he holds the green device away with his other arm. “See, they transmit the sound the other makes, cool huh?”
”What do you call this invention?”
“Erm… I don’t know. A Walkie-Talkie?”
“Sounds dumb. That will never be its actual name when you start selling this.” But Kacchan takes the orange one from him and Izuku can't be more secretly pleased.

“Sounds dumb. That will never be its actual name when you start selling this.” But Kacchan takes the orange one from him and Izuku can't be more secretly pleased.
He knew Kacchan would pick the orange one!
“I even made an in-ear version of this device, so I won’t have to hold it all the time, see?” Izuku turns his head to the side, to show Kacchan the miniscule device in his ear.
“I even made an in-ear version of this device, so I won’t have to hold it all the time, see?” Izuku turns his head to the side, to show Kacchan the miniscule device in his ear.
“Use this when there’s an emergency and you really need me.”
Izuku forces himself to get on the carriage and takes comfort in the fact that they have the walkie-talkies. At least it gives Izuku some peace of mind, in this situation that he cannot control.

And Kacchan can use it in case there’s an emergency.

Well, getting bored to death is an emergency, right? It’s in the middle of the day, and normally Deku is here telling Katsuki about a bunch of hobbits and the Shire.
Instead, Katsuki is all alone, sprawled on the huge bed and bored out of his mind.

Hmm.. he holds the blanket to his face, it still smells of Deku. Katsuki inhales it a few more times.
He can cook something, but it’s boring to eat it by himself. And he kinda misses Deku’s ‘uwaaaa so good’ comments on his cooking.
Katsuki finally gives in.

Katsuki finally gives in.
He takes the orange device and presses the button that Deku says to press.
...and shouts into it. “HEY NERD!!!”
He waits a few seconds later, pff. Piece of shit doesn’t wor-
The device speaker crackles for a second, and then “Ahh! Kacchan, there’s no need to scream like that!

I had the small earbud in my ear and I think you just damaged my eardrums!”
Heh. Deku is such a funny guy.
There’s a pause on the other side, before Deku continues again, “Are you okay?” This time his voice is gentle, and Katsuki likes to think that he’s a little worried. Good.

To be honest, he doesn’t like being alone. If he dies here, he’ll be alone and Izuku will be the one to have to find him. He doesn’t like the idea of that so he’s terrified as fuck.
He wishes Izuku is nearby, where Katsuki can hear him mumble or reach his hand out to touch that green hair.
So he tells Izuku instead, “I’m bored. Tell me a story.”
…and Izuku does.

Where Kacchan learns what jealousy is.
-------
Even though his situation is shit, Katsuki can’t complain because Deku–no, Izuku, dotes on him every time he’s around. Katsuki absolutely preens in the undivided attention of Izuku.

Even though his situation is shit, Katsuki can’t complain because Deku–no, Izuku, dotes on him every time he’s around. Katsuki absolutely preens in the undivided attention of Izuku.
He also enjoys the quiet evenings when Deku stops working. He lies down next to Katsuki on the mattress and they chat about life and shit until they both fall asleep.
To be honest, if Katsuki does indeed die here, it will be alright.
To be honest, if Katsuki does indeed die here, it will be alright.
Because he’s more than grateful for having the chance to experience *all of this* with Izuku, even if it was for just a short moment of their lives.
But knowing Izuku’s absolute pure determination, with resolve as strong as the steel around his heart, he knows Izuku will learn how to bend time and space before allowing Katsuki to die.
A/N: I just really love this quote :P Sorry. hahaha
Midoriya "I will do anything for Kacchan" Izuku
Midoriya "I will do anything for Kacchan" Izuku
In one of the nights when Deku can't come back to the shop, because he has to attend some social event, Katsuki keeps himself updated with newspapers. Apparently it’s a thing in this city. He can also go out, but he doesn’t want to risk passing out on the sidewalk.
That day, he sees Deku on the front page.
This is not the first time that Katsuki felt absolutely helpless with his situation. There has been multiple times when Katsuki cursed his bionic existence.
This is not the first time that Katsuki felt absolutely helpless with his situation. There has been multiple times when Katsuki cursed his bionic existence.
But at least the previous times didn’t feel like his imaginary heart was being ripped to shreds.
Katsuki hands shake as he clutches the newspaper in his hand.
Katsuki hands shake as he clutches the newspaper in his hand.
Midoriya Izuku, the son of the duke, is photographed on black and white on the front page of the paper, with two beautiful women, clutching on both of his arms. One is a brunette with a round face and the other has ash blond hair. Same as Katsuki’s.
But unlike Katsuki, they’re beautiful and whole… and undamaged. They don’t have their chest cut open and have a mechanical device stuffed in it.
No wonder Deku likes them. Katsuki throws the newspaper on the bed.
It ruins his whole mood.

It ruins his whole mood.
It stews in his head and becomes even worse when Deku comes back to the shop that evening.
“Kacchan, I’m here!” He hears Deku call from the back door. He remains in bed, with his back to the stairs. Katsuki can’t even bear to look at him. Katsuki doesn’t deserve to be here.
“Kacchan, I’m here!” He hears Deku call from the back door. He remains in bed, with his back to the stairs. Katsuki can’t even bear to look at him. Katsuki doesn’t deserve to be here.
He’s all broken, unlike the two other women with Deku.
The last step at the top of the stairs creaks, and Izuku’s voice is low and gentle, “Kacchan, are you ok?”

His eyes feel hot and he suddenly struggles to breathe, but he manages to snap at the nerd, “When are you gonna be done with my heart? What’s taking so long, haa?!”
He doesn’t even need to look back, he can hear the frown in Izuku’s voice, “Kacchan, what’s wrong? What’s —”
He doesn’t even need to look back, he can hear the frown in Izuku’s voice, “Kacchan, what’s wrong? What’s —”
Katsuki sits up and faces him, the thick blanket all bunched up in his lap. Why the hell are his cheeks wet? “I’m tired of sitting here while you work at a snail's pace! I thought you’re the best, haa?! But no, you’re out there with other women and going to parties!”
Deku’s eyes land on the newspaper on the bed, then back to Katsuki. Ah shit. Deku tries to hold back a smile, “Kacchan, were you reading the paper? Are you jealous?”
Crap. This is exactly why Katsuki needs to stay away from people. He's so easy to read.
“FUCK YOU! NO!
Crap. This is exactly why Katsuki needs to stay away from people. He's so easy to read.
“FUCK YOU! NO!
And who the hell are they anyway? Are they your girlfriends? Wives that I don’t know of?”
“Hah! Goodness, no!” Deku laughs. It sounds genuine. But Katsuki doesn't put his anger away even though Deku's laughter is like a soothing salve to his paranoid mind.
“Hah! Goodness, no!” Deku laughs. It sounds genuine. But Katsuki doesn't put his anger away even though Deku's laughter is like a soothing salve to his paranoid mind.
“That’s Himiko and Ochako. They are actually secretly together. We are all posing and keeping up appearances for society’s sake. I can assure you, there is nothing romantic between me to either of them. But they are desperately in love with each other, though.”
Somehow, that makes Katsuki’s non-existent heart feel relieved. His mind calms down, but he makes sure to continue giving Deku a suspicious stare. He’s not completely off the hook yet!
What has Katsuki become because of Deku? He has not been afraid before.
What has Katsuki become because of Deku? He has not been afraid before.
He wasn’t even afraid of losing his own life, but now? The thought of losing Deku terrifies him to his core. He wants Deku here, by his side. No one else can have him.
He needs to let Deku know that, maybe right before he dies or something. “I hate you, Deku.”

Izuku crosses the distance and joins him in the bed. “I like you, Kacchan.”
Katsuki’s hands are quick to cling on his collar and pull him down for a kiss.
He swears, it’s better than breathing.

Izuku breaks the kiss only to tell Kacchan this: “I told Himiko and Ochako about you. I told them that I cannot stop thinking about you. How every moment that I spend away from you feels like a wasted time.”
"Then stop wasting it and kiss me."
Izuku replies by pulling him down again for a deeper kiss.

In the end Izuku manages to test and come up with a power source viable enough as a replacement.
Essentially, what Izuku had come up with is plutonium, which can power Kacchan’s heart for literal thousands of years, at the very least!
In the end Izuku manages to test and come up with a power source viable enough as a replacement.
Essentially, what Izuku had come up with is plutonium, which can power Kacchan’s heart for literal thousands of years, at the very least!
Getting plutonium was not hard to smuggle, er–, acquire with his reach and money. The hard part was to get the materials to contain it. Plutonium is a strong radioactive chemical.
Thankfully, a few iterations later with Kacchan, Izuku managed to seal and contain it so that no one would accidentally inhale plutonium particles.
“Yes, yes, the joys of decaying radioactive isotopes! Just put it in me, Izuku!” Kacchan is lying down on the lounge chair, underneath the bright workbench lights that Izuku has dragged for better lighting.
Today is the day when they’re putting it in Kachan’s heart permanently.
Today is the day when they’re putting it in Kachan’s heart permanently.
“Kacchan! Please don’t say things like that when I’m handling actual radioactive chemicals!”
The plutonium is contained in a box with the same dimensions of the white cube. Except this time, it glows green.

The process of replacing the power source involves removing the cube from his heart. Once the white cube is removed, Izuku has only a matter of minutes to put his own contained plutonium in. Katsuki’s body can survive for a few minutes without it.
"Okay, are you ready, Kacchan?"
"Okay, are you ready, Kacchan?"
"Pull it out, love." Kacchan has the audacity to grin up at him like a maniac, teasing him further.
Izuku takes his pliers and carefully removes the white cube from Katsuki's heart. When he brings it closer to his eyes, something catches his attention.

He nearly loses all of his focus because of it.
For on the back of the cube, on the side that is not visible, are the symbols of his old mentor's name, etched in a familiar engraving that Izuku has memorized ever since he learned how to read.

“K-kacchan, the name on this cube… it's...” Izuku's hands begin to tremble, so he hastily places the cube on the table.
Kacchan stares back at him quizically, "Huh? What name?"
Izuku really needs to understand why it's there and how did Katsuki get this mechanical heart.

But he needs to save Kacchan first because he has only a few minutes without it.
He takes a deep breath and takes the glowing green cube with Plutonium. As soon as it snaps in place inside Kacchan's heart, he takes a deep breath. The cube starts to glow so much brighter.

It's a success! Kacchan inhales and exhales for a bit and then he gets up and paces around the room. His strides are wider and he moves so much faster. Izuku tears up at the sight immediately.
"Holy shit. You really did it!" Kacchan closes the distance between them and embraces him, nuzzling his head on the crook of Izuku's neck. "It works! I feel so much energized! Izu- what's wrong?"
"Kacchan, how did you know Toshinori Yagi?" Izuku holds the cube, showing the back side to Kacchan.
Kacchan stills in his arms and when he doesn't say anything, he sits back down and takes Izuku next to him. "I didn't know you knew him personally." He starts.

"Do you remember the story that I told you, on the night my power source almost ran out?"
Izuku sniffs, but he nods.
"On the day my mentor died, I said it was an accident and that it was caused me… but it was a lie." Kacchan brings his eyes down to Izuku's hands.

"He was trying to protect me and died doing it. I blamed myself for it, and I still do. But his last words to me, aside from telling me that it was not my fault, were to find the Mechanic, because he’s the only one who can help me. He told me I can find you in this city.”
It's like the floodgates have opened and Izuku's tears trail down his cheeks.
This whole time, Toshinori knew that Izuku has been the Mechanic. He knew that Izuku fulfilled his dreams and continued to do what he loved to do, and he entrusted Kacchan's life to him.

"He used to tell me stories of this brilliant Mechanic who can fix anything, who can create every possible invention. If he can imagine it, then he can make it, old man Toshinori used to say." Kacchan tells him.
He takes Kacchan's hand and kisses his palms.
He takes Kacchan's hand and kisses his palms.
He loves this man so much. Kacchan wipes his tears away and kisses his cheeks even though Izuku continues to sob. The light kisses on his skin help a little though.
"Now, come on you crybaby, come walk with me? I've got thousand of years worth of energy to burn!"
"Now, come on you crybaby, come walk with me? I've got thousand of years worth of energy to burn!"
Izuku coughs out a laugh in between his sobbing.
For the first time, they leave the shop together through the back door, and they walk holding each other's hands. Izuku doesn't care if the townsfolk see them or talk about them. Nothing else matters to him except Kacchan.

Katsuki's mechanical heart doesn’t jam or stall anymore, but he thinks he still feels it skip every time Izuku looks back at him with those green eyes. They're so bright and full of love for him.

Izuku makes him feel like his heart is real, that it pumps real blood in his veins, and that it’s not made of steel frame and iron cogs.
He decides to help out Izuku and challenge his ideas for new inventions, thus he will have to stay with him here for a really long while.

“For as long as it lasts.”
