Izuku sat upon his throne, listening to the suitor explain their reasonings as he had multiple times before with countless of other suitors.

He was bored. His wings hurt from keeping them folded for hours as he sat, each person stating their qualities and Izuku smiling his charming smile getting them to leave.

"Please your majesty! Give me a chance!" The man in front of him practically begged which made Izuku's-

Wings twitch a bit in dissatisfaction. He covered this as he leaned on his hand, smiling and looking at him with soft eyes.

"I will think about your proposal. Thank you for taking your time to approach me." He said like he was a broken record.

He's said it to everyone else.

Once the person left he was joyed to not see another person enter the throne room and he got up, instantly opening his wings and stretching. "Every single one was insufferable. Where are these people coming from?"

"It hasn't been easy turning these people away from-

Here for your sake." His guard told him, looking more tired than he normally did. "We've only succeeded in turning away two."

Izuku sighed, his wings looking towards the door as he looked back at Shinsou. "It's better than nothing and I thank you and the rest of the guard's-

Efforts of taking care of it. Maybe one day these will stop." He chuckled, starting to walk to where he wanted to. "I'm going to take a walk into the forest, if I may?"

"Have your powers been working alright?" Shinsou questioned making Izuku nervously mess with the rings-

Around his wrists and look back at him.

"I.. As alright as they can.. I think I can use my locater... I..I won't go far, I promise and I won't get lost!"

Shinsou looked at him for a long moment before sighing and nodding, "Go ahead. I won't limit your freedom."

Izuku happily smiled, his wings flapping showing such. "Thank you Shinsou! I'll be back in a decent amount of time so I don't worry you too much, okay?" He said before making his way out of the castle and making his trip to the forest.

Izuku hummed happily as he made his way to the forest. He admired the flowers that were growing in this spring so beautifully. He couldn't help but pick some of them and take them along with him and continued to follow the path he took.

He picked more flowers as he went and said hello to all of the animals that he passed by during his walk.

At a point he found a river and happily took a seat near it before he was going to head back as the path ended here and he needed to make sure he wouldn't get lost.

That was until a bunny made its way over to him, sniffing at his wings before hopping into his lap.

"Oh, hello! Oh you're adorable!" He giggled, petting the bunny gently as it rubbed against his stomach. He smiled and used the middle part of his wing to have a type of-

blanket for the bunny as it slept in his lap. He stayed there with it peacefully for a bit, listening to the water run along the river before the bunny perked up, sniffing the air.

"What's up, lil guy?" Izuku asked it, watching it wiggle its way from his wing-

And hop out of his lap, sniffing the air more. Before he knew it the bunny was bolting across the river to the other side of it.

"H-Hey wait! No it's dangerous out there!" Izuku called after it, instantly getting up.

He told himself he wouldn't pass this point..

But the bunny was going to get lost or hurt if he doesn't find it again..

He took a deep breath before flying after the bunny deeper into the forest. "P-Please stop running! You're going to get hurt!" He called after it but it kept running deeper and deeper in.

Izuku flew faster to try and catch up to it and was able to grab ahold of it.

"Aand..Gotcha!" He picked it up before stopping his flight noticing the bunny was no longer even trying to wiggle out of his arms.

He stood back on the ground as he looked around at the-

Clearing he stood in. It was beautiful. The sun shone down on it in every right way and the flowers looked brighter than he's ever seen before. He gently set the bunny down as he admired it all.

He's never seen an area like this before. It made him happy to be in.

"What brought you to this spot, little guy?" Izuku asked the bunny, watching it roll around in the flowers near his feet.

He giggled quietly before he sensed his wings were looking at something else. He was going to look but froze up upon hearing a deep, rough voice.

"Well..what do we have here?" The voice laughed, and took steps into the clearing. The steps were heavy. Izuku felt as the Bunny hid behind his foot and Izuku used the bottom part of his wing to protect it if need be.

"State your reason for being here."

Izuku tried to sound as confident as he could as he said that, bringing his wings to their full size. Despite this he kept his gaze down, hesitant to look.

"My.. I've seen many angels but you..you ate indeed the most beautiful. Your wings are gorgeous."

Izuku gasped quietly and quickly closed his eyes and got to look at the source of the voice through his wings.

Upon doing so he saw something he didn't expect..

Or well, someone he didn't expect.

"A demon." He whispered, opening his eyes, meeting his gaze.

"What a smart cookie you are." He laughed, stepping closer.

The demon in front of him had spiky ash blond hair and red eyes that could pierce through anyone and anything.

Horns laid ontop of his head and his own wings, though much different than Izuku's, were much-

More intimidating with how dark and how sharp they were, spikes and jagged tears in them.

Despite him having less wings than what Izuku had, they were still large, practically the same size as Izuku's.

At his side there was a wolf.

The wolf sniffed out the area just like-

How the bunny had done originally. The wolf stalked closer to Izuku, making him step back slightly, moving the bunny back as well.

"Don't worry. He won't hurt you." The demon told him, noticing his hesitance.

"And how can I be so sure?"

The demon looked at him for a second before chuckling, "If he wanted to he would have done it already sweet thing."

Izuku blushed at the affectionate name before shaking it off. "If you're wishing for me to leave I will."

"Now why would I want that?"

The demon stood next to him, gently running a hand along his wings. "If anything I want to get to know you. You look like you're fascinated by me too." He said, looking from his wings to him himself.

Izuku shivered at the touch and jumped up when the wolf-

Walked right behind him and lifted his wing that was covering the bunny with its head.

Izuku watched the wolf sniff at the Bunny before starting to groom its fur making the bunny stamp its foot happily.

Izuku smiled at them interacting before looking at the demon.

"Alright. But only because the bunny is happy right now!"

"Gonna play hard to get, hm? I can work with that." Katsuki teased, sitting down on the grass and Izuku followed suit, sitting down in front of him.

"I am not playing hard to get! There's nothing you're getting. I-

Don't even k-know you!" Izuku pouted but couldn't help the pink that dusted his cheeks.

"Well, let me introduce myself." He stuck his hand out, which Izuku saw now the ends of his fingers faded to blackened claws.

Izuku was mesmerized by how it looked as he shook his hand.

"Katsuki Bakugou. What's your name sweetheart?"

Izuku shyly looked away, "I-Izuku Midoriya."

"You know no matter how much you look away from me your wings and apparently these rings can't keep their eyes off me." Katsuki chuckled, leaning back.

Izuku sighed, looking back at him himself, "I've never met anyone that willingly looked at them the way you are." He whispered, folding his wings in.

"Really? I think that your wings bring out how beautiful you are even more." He told him, looking him up and down.

"Your freckled..your soft looking curls..your own eyes..it all pops more with your wings. Whoever doesn't like them is shit." He shrugged.

"All those suitors should take notes.." He giggled which made Katsuki tilt his head.

"Suitors? What are you, some kind of Prince?"

"Uhm...actually..yeah.." He shyly messed with hus cloak. "And I must start looking for a spouse. So many others have been trying to woo me and it's not working."

Katsuki instantly laughed hard at that. "Oh my g-god, those extras think they can woo someone like you?!"

Izuku pouted, tilting his head, "And that's supposed to mean?"

"I mean, look at you! Only the best of the best can even dream of a chance with you."

Izuku blushed more, "Be serious, Katsuki."

"I am being serious."

"Why are you being so nice to me?"

"Why wouldn't I be?"

Izuku groaned, laying back on the grass. "You just met me.."

"That's why I'm getting to know you."

"You're insufferable."

"I'll only get more persistent."

Izuku couldn't hold back the laugh that left his lips. He didn't know what it was but going back and forth with him-

Felt..freeing. He liked how Katsuki didn't just treat him a certain way for either being an angel or by being a Prince. He just treated him as a person and he liked it.

It made him feel alive.

So Izuku entertained the idea of getting to know one another. They talked and talked-

For awhile. Izuku saw how their pets cuddled up with one another as the time passed. Katsuki ended up laying next to him at a point.

By the end of it they were laughing messes.

"God..I didn't think I'd want to get to know you this much but here I am..I don't want this to end."

Izuku told him, looking up at him under the now darkening sky as the sun started to set.

"I don't either..but I'm sure your people need you or whatever.." Katsuki sighed, sitting up.

Izuku frowned and noddrd, sitting up as well. "I apologize."

"Why are you sorry, dumbass? Don't be..will you be okay making your way back?" Katsuki asked on a softer tone and Izuku nodded, holding his hand out. A hologram like compas appeared in his hand, "I will use this to bring me back."

"Alright..I better see you again soon." Katsuki stood up himself before helping Izuku up.

"I..I hope..my guards may not allow me out at least until I choose a suitor considering how long I was out today..But we'll see.." He smiled. "I had fun today..thank you."

"No, thank you for not instantly just running away from me." Katsuki chuckled, gently petting his wolf, waking it up. The wolf yawned before nudging Izuku's bunny, watching it wake up and honk quietly, looking at it.

The wolf gently licked the top of its head before picking-

It up by the scruff and holding it out for Izuku. Izuku smiled, taking the bunny from it and petting it.

"I feel bad separating them for now." Katsuki sighed, petting his wolf.

"I guess both me and the Bunny are sad to leave the new people we met." The bunny whimpered-

Quietly, proving his point. Katsuki ruffled his hair looking back at him.

"We'll see each other again soon, I just know it." He told him, gently hugging him. Izuku hugged back with his free arm and sighed happily.

He hoped he was right.

Izuku was allowed to explore-

The forest again after a week of having to stay in the castle due to worrying the guards by being gone too long.

He dealt with new suitors coming everyday wishing for his hand in marriage and he told them the same spiel of that he'll think about it.

He was happy when Shinsou allowed him to go into the forest again upon him giving him puppy eyes as well as using his bunny for extra reasoning.

So he happily walked with his bunny back into the forest, the bunny leading the way back to the clearing they've been to before.

Once they pushed past the bushes they were in the clearing and Izuku smiled watching the familar head of blond spikes perk up and look back at him.

His bunny ran over to his wolf while he approached, folding his wings. "Surprised you're here."

"Got a hunch that you'd be here today." Katsuki chuckled, watching him sit down.

"Is that code for you just come here until I'm here?" Izuku teased making him roll his eyes.

"Possibly."

"I think that's sweet. I'm sorry, they wouldn't let me leave."

"Must be shit being stuck in there. I know they're worried about your safety but damn."

Izuku just laughed, shaking his head before they started to engage in conversation. They talked just as long as they did previously, getting to know one another more than before.

Each week Izuku was able to come back after his duties at the castle and got to talk to Katsuki each time.

He learned of the battles Katsuki gone through and learned how it is where he lived.

He was always upset to have to leave him and always awaited when he'd see him again.

Today was another one of those days.

It had been a month since he first met Katsuki but it was also time for him to choose a suitor to be married off to.

He's seen so many people within the month and he wished there was just one person he liked and could choose.

But there wasn't. There was only the person in front of him and the final person left for him to meet outside of the door.

Every single person was insufferable but he had to pick someone.

He dreaded who he would have to pick, watching the person leave.

Until he didn't.

He watched the next person walk in and his eyes widened in recognition of the wolf at his side and the wings that currently covered him.

"My Prince, if I may.."

Izuku gasped quietly, his face heating up in a blush.

"To have your hand in marriage would be a gift-

I would cherish for my life."

Izuku watched him open his wings and bow before him, holding his hand out for him.

"Kacchan.." He whispered, getting up from his throne stepping towards him.

"What do you say, Deku? I told you only the best of the best could hope to-

Be yours. Will you allow me to be that best for you." He tilted his head, grinning at him.

Izuku giggled as he blushed more, covering himself with his wings. "Gosh, of course you would do something like this." He said before opening his wings back to their full-

Size and taking his hand. As soon as he did so Katsuki placed a gentle kiss on top of it and kneeled down in front of him.

"I accept your proposal as long as you promise to stay by my side and treat me with respect and honor."

"I swear to you that I will."

"Then it is decided."

Katsuki smiled and stood up before picking Izuku up making him laugh in his arms. "I won over those extras!"

"K-Kacchan! Put me down!"

Katsuki just shook his head, spinning him around making him laugh more.

He admired his laughter and admired his joy and once settled down they looked at one another with soft smiles on their faces.

"You're just always full of surprises aren't you Kacchan?"

"Well this surprise got me your hand in marriage and a kiss so I'm happy."

"A kiss..? But you haven-"

Katsuki cut him off by placing a soft kiss on his lips. Izuku's eyes widened before he melted into the kiss, wrapping his arms around him.

Once they pullled back Katsuki smiled at him. "Yeah a kiss."

"You're insufferable." Izuku giggled.

"Yeah, but you love me." Katsuki rolled his eyes.

Izuku sighed happily, leaning his head on top of his.

"Yeah. I do.."
