Here's chapter two! Sorry for the scene changes in advance. Here is Midoriya and Todoroki's chapter before Endeavor screws it all up...

They said meeting a fated mate was an indescribable feeling. If Midoriya and Todoroki could describe it, the feeling was both calming, like being brought to peace, and electrifying, an intense feeling of lust and passion that they'd never imagined. All it took was one touch.

It all began with different childhoods that would soon collide into a passionate fated bond. Midoriya was a quirkless omega who could never be useful to his alpha or beta. Or so Bakugou told and lorded over him as children. Kacchan never believed him when he said he felt he had a fated one, saying he only wanted to make himself feel better for not having a quirk. Inko told him that people with fated mates never felt that they were living life alone. No matter what verbal abuse Kacchan threw his way, Midoriya could hold his head up high because he never felt alone. Someone was always with him and each night was spent envisioning how he would meet his fated one. The only thing he was afraid of was his mate not approving of the quirk he inherited from All Might.

Todoroki's mother told him the wonders of having a fated mate, even though her story did not end as happily as other fated pairs. While having a normal mate was fine and well, it could not compare to the bliss and passion of a fated bond. Not many people had a fated mate, so Shouto felt special in that regard. With his mother's encouragement and the warmth he had in his chest whenever he thought about meeting his fated one, Shouto thought he could endure all of the shit Endeavor hurled at him. The abuse he went through was just a push until he met his fated one. He could still sleep well at night to his mother's comforting touch and the presence of his mate in mind. It ended when his mother was driven to insanity and burned him. He could never forget the searing pain in his face and the crazed look in her eyes. That wasn't his mother. That was what Endeavor created.

Ever since, he saw Endeavor as the monster his mother saw. Not only did he separate her from her fated one, he abused the two of them and his siblings for the sake of his ambition. If Endeavor stooped so low to start his ambition by separating a fated pair, then Shouto would protect his mate from experiencing the same fate. He was going to be a powerful alpha to defy the alpha that reigned their family with an iron fist. And he was going to be a hero using his mother's quirk. The idea of using his fire disgusted him. It reminded him too much of the man who didn't show his true face underneath the flames. He'll never use his left side ever again.

The idea of a fated one was put aside only when the two were training for UA. But as the first day approached, a strong feeling of warmth pierced through them as each boy entered the 1-A classroom. Midoriya was practically giddy while Todoroki kept a cool, calm façade despite the urge to smile. When Shouto first noticed Izuku, he saw a strong willed person who tugged the string meant only for his mate on his heart. For Izuku, he saw a boy who would one day be an amazing hero and it intimidated and excited him for reasons he couldn't put a finger on. They knew that they had a fated one somewhere in this room, but failed to make the connection to each other since they never made any sort of contact until the villain attack. Even then, the two were preoccupied with the villains to feel their respective alpha and omega howling that their fated one was so close.

After noting All Might's strange attachment to Midoriya, Todoroki thought he was simply a rival he had to best to prove that he could be a hero without the use of his left side. His alpha said otherwise, but Todoroki was too skeptical about Midoriya and All Might's connection to listen.

Until a touch at the Sports Festival.

The touch the two shared in the waiting room with their classmates sparked the sudden realization that their fated one was right there during the declaration of a rival. Midoriya had meant to stop Todoroki so he could speak to him, but the two froze as the contact electrified them into stopping all thoughts and movement. Todoroki's alpha and Midoriya's omega took over to finally rejoice after too many years pining after the other. Despite the suppressants Midoriya had taken in case his heat was sparked by his fated mate, they were practically useless as a stab of hot arousal slicked through his pants.

Todoroki reacted first, pulling Midoriya into a heated kiss and locking his arms around his waist. Lust and the need to claim and love his mate invaded any rational thought he was having.

'Mine mine MINE!' his alpha shouted, desperate to mark his mate as physical proof of their bond. Their tongues danced together and Midoriya's whimpers were overtaken by Todoroki's lustful instinct. Midoriya's omega more than welcomed the alpha's touch despite Midoriya's embarrassment, letting out squeaks of pleasure to encourage the alpha to continue. The pheromones were driving their classmates into action, some of the alphas and betas trying to physically separate the two while others held their breath or dove for medicine to ward off the heat from the fated pair. Iida grasped Todoroki from behind the chest, trying to pull onto his classmate with Kaminari and Tokoyami.

"Todoroki-kun, I understand how you must feel, but restrain yourself! We are all aware that Midoriya-kun is yours!" shouted Iida, hoping his voice would reach his classmate's ear. But it didn't go through. His strength was beginning to overwhelm them now that he was with his mate. Bakugou had Midoriya from behind with Kirishima as the latter tried to get his friend to calm down. Bakugou had a different approach.

"Deku, don't fucking suck face back, you fucking nerd! Don't one of you assholes have shitty tape or something? Tie these assholes up!" Sero bristled at the insult, but for the good of everyone else, he released tape from his elbows.

Instincts and reflexes heightened, Todoroki heard the stretch of the tape before it reached them, slamming his right foot on the ground and freezing Sero in place. His ice was jagged compared to than it usually was, setting their classmates on edge. So this was an alpha with an enhanced quirk.

Not wanting to make things worse, the others let go, Bakugou forcibly, to let Midoriya and Todoroki have those feelings sorted and sated. Bakugou wanted to fight an enhanced quirk, but Kirishima yanked him back. If a fight blew up here, then everyone would get sucked in. Instead, the others focused on excavating Sero out of his prison.

Midoriya and Todoroki were back in each other's arms, kissing one another heatedly. His quirk slowly pulling out of his control, Todoroki could feel his left side start to burn. However, the alpha was adamant on protecting his omega from being harmed by his quirk. Instead of an intense burn, all Midoriya felt was a warmth that spread throughout his body while the others began to sweat at the rapidly growing temperature in the room. His sweet scent drove his growling alpha into wanting to claim him, his slick wetting his boxers and threatening to run down his thighs. He whimpered softly, alerting his mate of his distress. He needed desperately to be claimed. He waited too long to join him.

And Todoroki was more than willing to claim him, Sports Festival be damned. His mate was far more important.

A loud, booming sound of laughter echoed into the room, stopping 1-A while they were chipping and melting the ice around Sero.

"I AM HERE!" shouted All Might, bursting into the room with his usual grin. The only ones not listening were the bonded pair. Ah, he noted with a chuckle, they must be fated. Midoriya did mention at one time that he thought he was fated to someone. This must be their first touch. All Might strode over to them, calmly yet firmly separating the two.

On instinct, Todoroki glared at the offending figure, finally seeing his childhood hero through the haze in his mind.

"All…Might?" he muttered, his senses returning to normal. The pro hummed thoughtfully. He knew Midoriya was the omega. Izuku told him that day on the roof. So Young Todoroki was his alpha. They'd be a formidable duo, judging by how frozen their classmate was. Todoroki growled, wanting to stake his claim on his omega without interruption. All Might chuckled. Quite a possessive young man, fitting for an alpha.

"Young Midoriya," he called out, snapping Izuku out of his lust by masking Todoroki's scent with his own alpha pheromones. "Calm your mate, will you? The Sports Festival is about to start and having the two of you in heat could throw off the balance in pheromones."

Midoriya gasped, looking over at his mate who stared at him longingly. As the omega, he had the responsibility of putting his alpha in check. All Might clapped his hands together.

"Let's give these two some privacy, shall we? Everyone, let's take our leave. And remember, Midoriya," he added, glancing at the green-haired teen, "control him."

The others slowly filtered out, Uraraka giving him a small smile and handing him the suppressants from his bag. He shook out a few and swallowed his pills dry, not bothering to bend over for the water fountain or else it would trigger his mate to mount him. Not like Todoroki would, but they did make out in front of their peers. Anything could happen.

Todoroki was taking deep breaths, trying to suppress the lust that refused to leave his system. His alpha was pissed at his hesitance to lay claim to his mate. Did he not realize how long they waited for this moment? But a cool touch instantly soothed him, hushing the alpha inside. He glanced up at the touch, feeling elated when he saw Midoriya.

"Are you calm now, Todoroki-kun?" He nodded, sighing as his lust sapped out of his system and left him feeling restless. Midoriya shyly looked away.

"S-should we forget about what just happened?" Immediately, Todoroki snapped up and glared at him. He didn't like rejection and coming from his fated mate was even worse.

"I dare you to repeat that." Midoriya squeaked, shaking his head a mile a minute and waving his hands.

"I-I di-didn't mean it like that!" Seeing he wasn't convinced, Izuku launched into damage control mode. "We just made out in front of our classmates and some people had their heats almost trigger and then five of them couldn't even keep us apart. Now Kacchan won't ever leave me alone seeing how strong you got and he'll mess with me to get in your head-"

He was muttering now, something Todoroki knew he did and now found endearing. However, what wasn't endearing was hearing Bakugou's name come out of his mouth.

"Do you have to call him that? It's too familiar." He couldn't mask the distaste in his voice. Midoriya blinked, feeling guilty all of a sudden for upsetting him.

"W-well, Kacchan was my old friend, so we had nicknames for each other. I can't really drop it now…it's stuck." When Todoroki frowned, Midoriya jumped to appease him.

"B-but I can try!" Todoroki shook his head, swallowing his discomfort. It's not like Midoriya meant it to sound affectionate and Bakugou was his childhood friend. Though he didn't like how Bakugou treated him.

"No, I won't change you. I don't like the name, but I can live with it." Midoriya nodded slowly, silently growing confidence as he met his mate's eyes again.

"Then I don't want you to hold back in the competition. I want to be in the top just like you do." The idea of potentially hurting their mate ached their hearts, but Midoriya was determined to become a hero even if that meant being at odds with his mate. It wasn't rare for omegas to become heroes, but it was uncommon. Often they are told to be extremely cautious given the drawback of having their alpha go ballistic when they're in distress.

But Todoroki agreed. Even though Midoriya is his fated omega, he still wanted to fight him because of his connection to All Might.

Shouto should have expected to open up to Midoriya sooner or later, but he hadn't expect it to completely pour out his anguish and soul the same day they met. Maybe it was their bond that helped save him, but Todoroki was moved by Midoriya's passion during their fight. Was this what his mother meant about a loving, fated mate? Midoriya risked hurting himself and broke his own bones to free Todoroki from the confines of his self-doubt, stubbornness and the influence of his father. His true potential and his left side revealed itself with the encouragement of the one fated to love him. But he was still confused about what he should do with his quirk. And the urge to finally see his mother again after so long was more important than winning the festival. The only thing he knew for sure was that Midoriya saved him at the expense of himself. He wasn't going to let him leave his side at this rate now that he was so attached.

While Midoriya was upset at throwing away his chance at exposure, he couldn't regret how peaceful and remorseful Todoroki was at his side after the fight. Throwing Endeavor's nastiness back in his face earlier for the sake as his mate's happiness was a proud moment for him as well, but the tender moment the two were sharing alone in Recovery Girl's infirmary sealed the two's bond to a permanent relationship.

Todoroki held Midoriya's hand gently, remorse and his calm pheromones drifting in the air. The others had left to give them some more privacy after making sure Midoriya was okay. Recovery Girl quickly tapped him before she left to not have and 'moments' while Midoriya was recovering, but the two were too engrossed in each other to blush or acknowledge her.

"I did this to you," he stated, fingers gliding over the scars that now marred his mate's hand. Midoriya shook his head.

"Please don't blame yourself. This is something I have to live with. I'm sure I'll have plenty of scars later." Todoroki's eyes widened a tad.

"I'm going to prevent any more scarring on you. While I won't stop you from being a hero, that doesn't mean I'm okay with letting you go head first into danger." He was the impulsive type and considering how he jumped into the fray during the USJ attack, Todoroki doubted it would be the last time he'd do so. Midoriya laughed, a sweet sound that rang melodiously in his alpha's ear.

"Fair enough. Please take care of me from now on." He tilted his head as he spoke, smiling brightly at him. What angel had Shouto pleased to have this one by his side? His mate, his omega, his companion was simply too pure.

"When did you want to get married?" The words tumbled out of his mouth, but he didn't regret it one bit. Midoriya blinked, face turning as crimson as his alpha's hair.

"Eh?!" Sadly, the two could not get married so young, but they'd work on it. Might as well plan it earlier so wedding stress wouldn't be as bad as the date drew closer. Considering how Midoriya began to freak out, Todoroki had to calm and ensure him that he was joking. Even though he wasn't. He leant in to kiss his forehead, breathing in sharply as he caught his mate's scent. He shifted to kiss him firmly on the lips, the gesture shyly returned.

"Todoroki-kun, please don't go too far," pleaded Midoriya as he pulled away, unsure if he could stop them both with desire looming above their heads. The barest smile appeared on the alpha's face.

"Of course not." They resumed kissing, the kiss innocent compared to the first one they shared while the warmth of Todoroki's quirk blanketed them.

Classes continued per usual after the festival and considering the incident of the two getting hot and heavy in front of their peers, Aizawa was nagged to do a crash course on mates to his students given it was the time of their puberty. He grumbled and groaned about it, but he made sure the little shits were all listening so he wouldn't have to repeat any information.

They learned from class that even though the omegas of pro heroes were easy targets to villains, it was wise not to give chase. Strong alphas sink into a murderous rage when their omega was harmed or distressed by a villain. One hero saved his omega by committing an entire slaughter and was stopped only by his omega limping out of her confinement to hold him. The incident was so shocking that they kept it out of the media so the hero would not be painted as a monster when it was his alpha instincts that reacted.

The thought of Midoriya being in that kind of danger frightened Todoroki. They did have arguments from time to time about Midoriya's bone breaking quirk and the possibility of being kidnapped by a villain, but his strong will to become a hero assured his mate that he was making the right decision. Could Todoroki also lose his sanity if Midoriya was in danger? The thought was vulgar and he'd rather not lose control, but his alpha reasoned inside him that he had to be willing to exhaust all options if it meant protecting his mate.

The walk home after school was more chatty than usual with everyone throwing in their thoughts about mates.

"I wonder if finding a mate will be easy for me. I've never felt a connection like the one Deku has, so I doubt I'm fated to someone," hummed Uraraka as they left the school. All the girls sighed in unison, understanding her plight.

"Mates are gross, who needs 'em?" grumbled Bakugou, stomping each step with disdain. He was mad that Todoroki didn't use his fire during their battle and that he was wrong about shitty Deku not having a fated mate, but no one really cared about his thoughts.

"I can't wait to find my fated mate!" gasped Mineta, drooling as he imagined his fated one as some busty chick who would be the first and only woman who would allow Mineta to touch her boobs.

"If you have a fated mate. Fated mates are just as rare as quirkless people," Tsuyu pointed out bluntly. As Mineta began to cry, Midoriya winced as she brought up quirkless people. He was in that demographic a few months ago.

"Having a fated mate is like a soulmate, right? We're all meant to be with someone, just not as in tune as fated ones. I think they're lucky. I hear it's amazing," praised Kirishima, winking at the fated pair in their group.

"Yeah, you guys are lucky, all right. I hear it's a feeling you have until you two touch. That's so annoying. What if I have a fated mate but I wouldn't know unless I touched everyone I meet?" whined Kaminari, kicking a lamppost they walked by. Jirou rolled her eyes.

"Depends. If the only times you feel connected with someone is when you see someone hot, then chances are you aren't a fated half. There's a huge difference between mates and fated mates. Join the party of normal people and work hard to find someone who can deal with your 'amazing' quirk," she added, nearly busting out laughing at the end. Kaminari joined Mineta in crying.

Iida hummed in thought. "What does concern me is how much someone's quirk is affected when their mate is in danger. My older brother and his mate aren't fated, but at one point he lost his mind for a moment when she was hurt during a villain attack. Fated pairs have a deeper bond, so that would mean…"

They all looked over at Midoriya and Todoroki who were both preoccupied with reading Midoriya's notebook together. Only Midoriya could keep the half-hot, half-cold alpha placated when he reacted to Midoriya in any sort of danger. As one, the class sighed.

'Please keep Midoriya protected!' they prayed, clapping their hands together.

They reached the crossroads where everyone would split up and head home, but Izuku and Shouto stayed put for a minute longer.

"Are you heading to the hospital, Shoucchan?" asked Izuku, growing accustomed to using the nickname for him. Shouto smiled a little. It felt nice to have someone know his thoughts in case he was uncomfortable voicing them.

"Yeah, I'm going to see my mom. And…" he trailed off, not able to meet his eyes. "I'm going to tell her about you. About us."

Izuku's eyes widened. He knew Shouto was reconnecting with his mother little by little, but was it necessary to bring him up so soon? They were dating for a couple weeks now. Maybe in a month or two, but now? Inko met Todoroki a few times and knew about their fated bond, but that was after she came home and saw the two in a deep kiss on Midoriya's bed while her son was supposed to be nesting. Todoroki read his mind just as he did.

"It's necessary now. You're my fated omega. I want her to know the one who pulled me out of the shit I was going through." They didn't mark each other yet since Midoriya's heat was still far off, so clinging to one another when they could was a clear indicator that the two were together. Endeavor saw this a few times and ranted about it, but Todoroki couldn't find a fuck to give him.

Midoriya smiled gently. "Then I'm okay with it. Will you come over tonight? I feel like my mom is making more food lately in hopes that it'll entice you to come."

Todoroki appreciated Inko for both birthing Izuku and for making him feel like he was a part of the family too. She was going to be his mother-in-law one day and Shouto couldn't ask for a kinder, understanding woman. He agreed and the two shared one last kiss before they would meet at sundown.

While his alpha disappeared from sight, Midoriya smiled to himself and turned to the direction of his home. As he quietly made his way down the street, he suddenly tensed when a slightly familiar alpha scent triggered him to halt. The scent was similar to Shouto's, but unlike Shouto's warm presence, this one was hostile and demanded submission.

And it belonged to Endeavor. The Fire Hero emerged out of the shadows with his flames burning brighter than he'd ever seen them, striding towards him with purpose. His eyes mirrored the disgust he felt from seeing the two so close.

"Midoriya Izuku." Izuku gulped, his inner omega intimidated by him.

"E-Endeavor," he said softly, nodding to the hero. His large hand clamped onto his shoulder, making him flinch. Fated to his son or not, he was still an omega, Endeavor thought with a smirk.

"Come with me." Midoriya tried to dig his heels into the ground, but it only served to piss Endeavor off. "Walk!"

In submission and fear brought by his instincts, Midoriya unwillingly complied. His omega chose safety over stubbornness.

Chapter two is done! Apologies if it seemed rushed in some areas, I wanted to show a brief start up in the relationship to what it has become now. The next chapter shall be why this story is titled 'Lose Control.' My fanfic style is to add previews to the ends of my chapters, but I totally overlooked that here because I was on fire writing this. Next chapter preview:

"He would never treat me like that. You, maybe, but I'm his fated omega. He was the one who kissed me first. And quite intensely, given he's a strong alpha like you say."

…

"I am the reason for your existence, your power! You should be listening to me!"

…

"Y-you…you hurt him…"
