Izuku has a big problem.

It's not about his job. Izuku loves his writing career (despite using a pseudonym). He's bought a good house, has great friends, and his neighbor is his best friend.

The problem technically isn't even his...it's his main character.

#BKDK #BakuDeku

'Deku' is a great protagonist. He's doesn't let his lack of magical power stop him from going on epic journeys with his friends.

He collects an elite group of friends to travel with him, and fans all over the world tune in each novel in order to see where they go next.
3
When he starts the story, his plan for Deku's love interest is simple. Uravity is a witch with a heart of gold, and a perfect match (according to his publicist) for the endgame.

And he thought so too, until he decides that group's a little... too sweet.

They need some fire.
4
He doesn't mean to base the dragon tamer, Dynamight, so close to his own best friend's entire being.

It's Kacchan's fault, coming over for movies and pizza the night he's trying to brainstorm ideas.

The natural snark under his pretty scowl sort of writes itself into the story.
5
And readers love Dynamight. He quickly becomes a fan favorite, not that Izuku blames them.

Despite having plots and romantic scenes he should be writing, he ends up adding Dynamight into interactions Uravity is meant to be in.

Its enough to get fans talking about 'DynaDeku'.
6
He thinks Toshi, his manager, will scold him for dragging out the build up between Uravity and Deku. They've only had few scenes together over the last book.

The kind man gets the wrong idea. "You know I'll always support love of all kinds. Dynamight seems to make Deku happy."
7
"Oh, that's not-" In his defense, Izuku didn't mean to bring his own sexuality into his stories.

Maybe its an oversight to make a character who is strong, intelligent, brave, and handsome enough to never wear a shirt.

(Fans might notice how often he describes the last fact.)
8
Dynamight and Deku becomes his most popular ship, despite the goal still to have his main character end with Uravity.

Or, he says this to himself, despite following several fan artists who make their love of the two men quite known.

And then the hot springs scene happens.
9
The night before he gets a burst of inspiration, Kacchan comes over. It's a normal hang-out; drinking cheap beer and touching each other to try and win the video game.

He likes spending time with Kacchan. Loves it, even. Because Kacchan is his person, his safe space, his Dyna-
10
"Why are ya red?" Kacchan's little nose crinkle softens Izuku's heart without effort. The alcohol makes him wish he could wake up next to the beautiful face every day.

For now, he flops his head on the bed they're sitting against, falls asleep to something caressesing his cheek.
11
When he wakes up the next day, its under warm blankets and with a head full of ideas. He doesn't know where the inspiration comes from, or how he's able to write so much in one day.

But the words flow out like magic, except the result of this inspiration is... well... different.
12
He knows throwing Dynamight in front of Deku to protect him from the poison daggers sounds romantic, but it just makes sense! He's the tank, and Uravity is on the other side of the battlefield.

And since Deku's the only one there, of course he has to take care of his wounds.
13
Maybe he didn't need them to go alone to a secluded hot spring.

And Deku undressing Dynamight in the moonlight to rub medicinal cream over the injury can be seen as 'intimate'.

But Dynamight, with both naked and wet, wiping blood of Deku's cheek fondly like he wants to kiss-
14
"Oh." Izuku's hands fall from the keyboard.

He stares in surprise at what he's created. Because the memory of last night floats back, and muddies up the lines between reality and fantasy.

Does he want Dynamight to kiss Deku, or... Kacchan to kiss him?

"I need to take a break."
15
The shower doesn't have the power to wash away his rapid heartbeat, but it does make him feel a little better.

Over the downpour of water, he doesn't hear his front door open. Doesn't know about red eyes scanning his living room.

Can't remember he left his rough draft open.
16
But when he leaves the steamy room, he nearly drops his towel off his hips when finding Kacchan on his couch, computer sitting on his lap.

"Ka-Kacchan!" He shouts, body tense when the other peers up at him over the screen. "What are-"

"Dynamight better not wimp out here, nerd."
17
Izuku gapes, unsure how to process Kacchan's continued comment. "Because he's a dragon tamer who just tried to die for this idiot. He's not gonna let him half-ass flirt with Pink Cheeks when they're naked-"

"Wait, wait, wait!" Izuku finally gasps out. "You read the series?"
18
"Hah?" Kacchan scowls, like the question's stupid. "Course I do. You based Dynamight off me, and he's badass."

"How did-" There's too many thoughts to focus. "I-but how? When?! How many people-"

"Just me. I've been reading your stuff since we were six. I know your style."
19
Though he gets some answers, another one pops into his head. "And you... want Dynamight and Deku to... to get together?"

"That's the endgame, right?" The quick question catches him off guard. "If you didn't want then to hook up, why did you write them like us?"

And that's...
20
He needs to get his ears checked. "Kacchan, you may be my inspiration for Dynamight, but I'm nothing like Deku-"

"Are you that stupid?" Then Kacchan's up on his feet, walking toward Izuku with a determined stare. "Cause from where I'm standing, you're his spitting image."
21
In a heartbeat, he's pressing a bare back against the wall, with large hands on either side of his head.

Kacchan stares down at him. For a moment, Izuku remembers why he's the model for the dragon tamer. He feels like he's back in the shower from the steamy heat between them.
22
"Deku's an idiot." Kacchan starts with an insult that Izuku hears weekly. "He's self-sacraficing. He's too kind to those who hurt him, like evil wizards... Or assholes who bully him in middle school."

"Kacchan, you weren't-"

"He sees hope where others find personality flaws."
23
The softer tone makes Izuku swallow, left speechless when a thumb moves over and smoothes down his cheek.

"Deku has a heart bigger than his head. Tries to hide it when he thinks it'll hurt the person he wants to hand it to. But Dynamight's not stupid. He's fucking selfish."
24
The words holds a growl that he'd expect from his character, not the man leaning close enough to murmur on the edge of his mouth.

"Dynamight ain't nice. He doesn't care about anyone but Deku. And he's been patient, but you write him like you want him to snap and devour Deku."
25
Izuku grasps the wrist near his face, turning flushed cheeks to bury words in Kacchan's palm. "He wouldn't do that. Dynamight's...he's brash, but he won't hurt Deku again. They have a special connection, Kacchan. One for only them to share."

He wonders who they're talking about.
26
"Then why the fuck didn't you have them kiss? Its been years, dumbass."

Izuku tries to hide his embarassment when he peeks from the corner of his eyes, taking a (mostly calculated) chance. "Well, I need to figure out how Dynamight would kiss Deku. Get some... some research."
27
He doesn't worry that his hint's too bold for long.

With a smirk too devastating for words, Kacchan grabs his face in both palms. "If Dynamight was gonna kiss Deku, it'd probably be something like this."

Even with the warning, Izuku's mind still goes blank at the first contact.
28
The exchange has too much history for a first kiss. Izuku doesn't notice the towel falling when he's pressed into the wall, eager to feel the body against him while their mouths move together.

Hands travel down his bare torso, fingers teasing his spine to arch from the surface.
29
One kiss becomes two, then becomes a lot more when Kacchan carries him to his room.

The kiss is written hours later between warm sheets, licks and nips along his shoulders and back tempting him for round (he thinks) four.

And maybe Izuku's problem isn't so big after all.
30
The only self-insert story I'd ever read!

I wanna write a story with the Fantasy AU. It looks so fun! One day I will for sure.

But hope you enjoy. Can't believe we're one week away from my new story release on Ao3. And tomorrow's part 4 for loophole.

LMK what you thought!
