Story: When you're away from your Soulmate for a long time, it kind of drives you nuts, you know? So Izuku and Enji have been apart…and Enji doesn't take it so well. Cue his return and things turn a little strange.
Set as an AU canon divergent fic.
Spoilers: No, not really?
Warnings: Age disparity, same-sex relationship
Pairings: Izuku/Endeavor

A/n: Hm, I swear –wishing people die or saying they need help just because they like something as simple and fluffy as this…That's just sad. If you have nothing nice or respectful to say, don't.

1. Don't like, don't read. Reading and leaving a (haughty) review is silly and more work/issues on you.
2. Not pedophilia; more ephebophilia. Also again of consent, not just in Japan. Look it up. If you're going to be judgmental, there's the door. Age difference couples are a thing and this is fiction anyway.
3. This is a humor, fluffy, Soulmate AU (also taking place when Izu's 17 and Enji has already become #1 in the manga). Not meant to always or completely be in character.
4. Otherwise, open mind, open heart, welcome and I hope you enjoy~

Miss You Like Crazy

"If you're sleepy, sleep."

Izuku yawned, head drooping every few seconds as his eyes kept threatening to close. Shoto gave him an exasperated look, but he waved him off as he yawned again.

"Is Father giving you problems again?" Shoto asked, shaking his head as he narrowed his eyes at Izuku.

Izuku blinked several times to try to wake up. He gave Shoto a sheepish look.

"He's antsy."

Shoto snorted quietly, closing his book as they gave up on studying. "Of course he is. I'm guessing you can feel him through your bond and he's going crazy wherever he is."

"The Soulmate thing is new to us," Izuku shrugged.

"It's been nearly over a year," the other boy drawled, giving him a look. "Face it. This is just Father."

Izuku finally just laughed, shrugging again while suppressing a yawn. "Enji can be overzealous about our Soulmate Bond and our time —or lack of time —together."

"He has been working a lot lately," Shoto begrudgingly admitted. "It's been a while since he was around the city, much less around here. It's been what? Three weeks?"

"A full month," Izuku muttered, depression leaking into his voice. "He's been kept busy."

Shoto patted his head awkwardly, giving him a sympathetic look. Or as visibly sympathetic as Shoto was capable of.

"I forget the distance and lack of contact affects you too," Shoto said. "Don't worry about it, Midoriya. He'll be around soon enough. Now go to sleep —you look like you're about to drop dead."

"Yeah, I am pretty sleepy…" Izuku said. Feeling tired and not knowing what else to do, Izuku decided that sleep was the best option and got himself comfortable.

As was expected, Shoto made himself at home on the futon he'd brought over to sleep over in Izuku's room, not bothering to ask if he could stay over. It wasn't long until the two of them slipped into sleep…

Then the door burst open and Shoto shot straight up in fright from the loud bang and unexpected occurrence (He was surprised Izuku had slept straight through that!). There in the doorway was his father, panting and slightly hunched over. Staring at each other, there was a sort of awkward moment before his father nodded at him and then strode quickly into the room, located Izuku, and then picked up the sleeping boy with one hand, turning around and carrying him out of there without another word.

Shoto shrugged and lay back down, intent on at least being able to grab some sleep for himself.

Toriyama Kiku was having a great time. He and his cohorts were going to make it big this time, having successfully broken into the jewelry store without any hassle, and easily picking up all the diamonds they could desire.

Then things went downhill and shit hit the fan the moment there was a huge burst of fire through the entrance and of all the fucking Pro-Heroes to appear, it had to be Endeavor.

Kiku blinked.

Wait…what on Earth was the Hero carrying? To his shock and confusion, the tall, large Hero, with his clearly defined muscles and fiery flames surrounding him (looking utterly terrifying as he stared them down) was holding a…teenage boy in one hand.

"Got something to say?" Endeavor growled, hand easily keeping the teenager up and his Hellflame flickering dangerously.

Kiku glanced at the kid, wondering what was going on.

"Say one word," Endeavor said threateningly, bringing the boy closer to himself. "I dare you."

Nope. Kiku valued his life too much.

But that was clearly not the case for everyone.

"Hey, why are you holding that kid for?"

Kiku mentally shook his head. It was clear that despite looking intimidating and ready to kick ass, whoever that was was important to Endeavor and someone he didn't want to let go of.

If, at the other guy's stupid question, Endeavor would leap forward and start systematically beating everyone to a pulp (all the while keeping hold of and still being careful and protective of the boy he was holding onto), then all Kiku could say was that he should've known this was coming the moment that other guy opened his mouth.

Enji felt the distance between him and his Soulmate. He felt like crap, even though he was pretty damn sure Izuku was fine at his school. All these damn missions were getting to him though, and he missed Izuku like hell.

Tonight was it and was just supposed to be a plain patrol of his area in the city. He'd only started, but…Spotting fire in the horizon, Enji just said "Fuck it" and booked it over to U.A. It's been way too long and the Soulmate Bond had been haunting him practically the entire time he'd been away from Izuku.

So if Izuku was sleeping and he'd managed to wake up his son, Izuku was a heavy sleeper and Shoto can just deal with his shit. He wasn't going to spend another goddamn minute away from his Soulmate if he could help it, especially now that he was in the same city finally.

Which brings him back to the present, holding onto his Soulmate with one hand and staring down these bunch of dumbasses. Keeping a secure hold on Izuku, Enji launched himself forward. He didn't bother using his flames to attack, even if they surrounded him more intensely than usual (although he was careful around the hand holding onto his Izuku). Instead, he landed closed fist punches into one man's gut, and then kicked out with another leg at another idiot nearby that had jumped towards him in a panic (though his face said that he had regretted it the moment he did it —which was too late, as Enji had already kicked out at that point). Since he was holding onto Izuku, he had to be careful. Just not as careful as these criminals were probably hoping he'd be restricted to, given he was still capable of going all-out and kicking all of their asses.

When he finished with the lot of them, he tied them up with one hand, refusing to let go of Izuku.

"Who's..who's the kid?" One of them asked again, whimpering a little bit. Goddamn, did he have some sort of death wish?

"None of your business," he said shortly, eye twitching.

He called up the police and impatiently waited, bringing the teen in closer and wrapping his arms around him. Hearing the soft sigh coming from Izuku, who curled in closer to him, Enji held on a little tighter and softened. The police came and he finally got to leave, ignoring the looks he was getting from everyone. Walking down the street, Enji enjoyed the quiet as he held onto Izuku.

"I really missed you," he murmured into Izuku's green hair.

He heard him mumble "Enji…," putting what was probably a silly grin on his face. It was good the street was empty, otherwise he'd have to put his Hellflame to good use.

When Izuku started waking, he could already feel the large, warm hand rubbing his head gently. Confused but also calm for the first time in what felt like forever (as well as the Soulmate Bond not actively causing a crushing loneliness and emptiness as it had for the time he'd been separated from his Soulmate), Izuku slowly opened his eyes and moved his head up. As he'd guessed he'd see, Enji was there and looked concentrated on what he was working on.

"What're you doing?" he sleepily asked as he yawned, blinking blearily.

Enji looked down, briefly looking surprised before he gave him a fond look. "I was back in the city. I didn't want to be apart from you anymore."

Izuku gave him probably what was a sappy smile. He'd missed him too, so he wasn't really protesting. Though he did realize his head was on Enji's lap and that the man was apparently working on paperwork while caressing Izuku's head. Also, he was pretty sure he'd glimpsed the plate of kuzumochi off to the side of Enji's papers.

Kuzumochi?

Where in the world were they? Izuku tried looking around, but it was hard in the position he was in.

"Enji, where are we?"

For some reason, the older man started to look embarrassed, so Izuku gave him a look.

"Well, my home was too far away and there was no way I was going to just bring you back to U.A. after taking you from there so abruptly. So…"

"Enji-san, do you want more tea?" Izuku heard his mother call out and he sighed while Enji gave him a shrug.

"No, thank you, Inko-san," Enji called back while Izuku just buried his face into the other's stomach. He was warm and comfortable and still sleepy. He should just go back to sleep, damn it. If they were going to stay the night over in his apartment's revamped guest room, then Izuku was just going to get that much needed (and better now that Enji was there) sleep, Enji could have his kuzumochi and calmly focus on his paperwork, and apparently his mom was happy to have an impromptu visit from them.

"Izuku?"

"Yeah?" he muttered, already falling back asleep.

"Goodnight."

That made him smile against Enji and he rubbed his face against him contently.

"Night…" he mumbled.

He really wasn't looking forward to having to explain to his school (and All Might!) just why he'd disappeared from the dorms in the middle of the night.

But that was tomorrow morning's problem.
