Just because Katsuki now had a newly acquired crush on Shouto does not mean his crush on Deku had dissipated. That would take a long time to disappear.
Katsuki had gotten up at five in the morning exactly one week and a day after the Mytho incident. It was for his weekend training. He observed five other people up and doing various tasks around the common room at this ungodly hour. There was Deku who was being his selfless self and making breakfast for the class even though he looked dead on his feet and sucked ass at making any type of food. Katsuki noted the get up Deku was sporting was more peculiar than usual. First and foremost, Deku looked like he hadn't slept in days. His hair was more of a mess than it was almost every other day, which Katsuki didn't think possible. He was donning an oversized shirt that suspiciously smelled like Hitoshi, but surely that was Katsuki's mind making stuff up. The shirt was so big the omega wasn't even wearing pants. This was not abnormal though, it happened every weekend on lazy mornings -well, not the zombie-like look and the messy hair, but the Hitoshi-smelling shirt was normal. What was really odd was the thick choker around his neck that didn't look the least bit comfortable and the gloves that reached all the way to his elbows.
Katsuki wasn't dumb, they were obviously scent blockers for when an omega was in heat, but that couldn't be. Deku had more self-preservation skills than that… right? Yeah, no.
Deku was in heat so what in holy hell was he doing chores for? Dumbass. He should be resting. This time period was very stressful for omegas not mated. Based on educated guesses, Deku had been in heat for three days now and he was almost at the peak. What the fuck had the stupid omega been doing at school? Deku was going to be the end of him, he swore.
Katsuki didn't have time for this right now though, Tokoyami, Yaomomo, Shouji, and Kyoka were here if anything went wrong. Yaomomo and Tokoyami were already watching him with concern, about ready to make him take a break.
Katsuki sighed, he would shorten his training regime to only three hours so he could be back sooner for Deku. Then he could force Deku to stay in his room for three or four days to get over the heat. Maybe they could cuddle? He heard that helped omegan heats.
First things first, his training.
Katsuki had lost track of time and accidentally trained for four hours. It was fine though, his usual time was five hours.
With Deku on his mind, he sprinted back to UA high school. It took ten minutes. Pretty good, considering he was four miles away from school. He kicked open the door, giving him a sense of deja vu. Last time he did that wasn't Shouto lifting up a couch or something? Shouto looked very hot lifting couches.
He looked around, it was now nine in the morning. Meaning almost everyone's lazy asses were still asleep. With the exception of a few people of course.
Shouto was sitting on a chair in the kitchen on a stool. There was heated soba getting cold next to the boy. He was scrolling through his phone, but he looked up when he heard the door crash open. Shouto blushed. That's weird, Katsuki thought.
Denki was laying on the couch with his arms over him like a corpse while he stared at the ceiling unblinking. Maybe he was dead? Denki looked a bit like he just saw something he wasn't supposed to. Eijiro was doing push ups and Shouji stared at him with concern. Kyoka was sitting on the couch next to Denki's face while blasting music through her earphones.
Katsuki frowned then turned to Shouto who was staring at him, "Where's Deku?"
Shouto frowned, matching Katsuki, "He's going around the dorms asking our classmates if they want him to deliver their laundry to the wash. Yaomomo and Tokoyami convinced him to stop making breakfast so he took that as an invite to do a different chore."
Katsuki said gruffly, "Tch, dumbass."
Shouto nodded in agreement and Katsuki's face involuntarily morphed into a smile. Unfortunately, Shouto saw it before Katsuki could pretend it never happened. Apparently, Katsuki's smile was contagious because Shouto smiled at Katsuki's smile. Shouto said, "What did I do? Why are you smiling?"
Katsuki started to walk away, "Nothing."
Shouto jumped off his chair, following Katsuki. Shouto hummed, "Then why are you smiling?"
Katsuki pressed a button on the elevator, calling it to their floor. The pair was standing next to each other now. Katsuki replied, "What? Am I not allowed to smile?"
Shouto turned to Katsuki and the blonde haired alpha did the same, Shouto raised a brow and gave him a serious look, "You never smile."
Katsuki scoffed. The elevator finally reached their floor and they both got in. They stood in silence on opposite sides of the elevator until the machine rang, notifying they were on their floor. The doors opened and they got out. They both walked in a single file line, Shouto walking behind Katsuki. The only sounds were their footsteps on the carpeted floor and the occasional snore. They reached Katsuki's door. Finally, Katsuki turned at a rapid pace and faced Shouto.
Katsuki said, "Why are you still here?"
Shouto retaliated, "Why did you smile?"
Katsuki opened his door, "I'm taking a shower now, bye."
Shouto just stared at the blonde.
"...What now? Did you want to join?"
Shouto's face lit aflame. "N-no."
"Your soba is getting cold."
Katsuki had gotten into his room with only his head peeking out.
The last thing Katsuki saw before he shut the door in the bicolored boy's face was the horrified look on Shouto's face as he thought of his poor soba alone on the table, left to face the wild beasts the two called classmates.
Katsuki is one of those magical people who can take really short showers and be sparkly clean when he finishes. Unfair, I know. Katsuki was out in ten minutes with his hair sopping wet but still managing to be spikey as ever. How? No one knows.
Little did Katsuki know, in those ten fateful minutes, chaos had unleashed in the common room.
Once Katsuki was dried off and had gotten dressed, he took the steps two at a time hopping down the stairs with little to no effort. When he reached the bottom, he called to everyone in the common room, "Hey, what do you guys want for break-"
That's when he saw everyone who had been previously lazing around was crowded around a form. They were murmuring to each other. Some attempted to touch the thing laying on the ground before someone else would kick the hand away.
Aizawa-sensei suddenly appeared next to the crowd, "Give him some space. You guys are supposed to be heroes, right? Didn't you take a class for situations like this? I swear, you guys all collectively have one brain cell. Move out of the way."
The group parted, revealing the form to be a passed out Deku. Katsuki's eyes widened.
Aizawa scooped up the unconscious omega and carried him in his arms. Aizawa mumbled, "Problem child- can't even take care of himself. We told him to take it easy and three days later I find him passed out on the ground obviously at the climax of his heat. Next time we're forcing him to take his heat days off school. I told the staff they should've sent him home."
Katsuki put together all the pieces coming to a solid conclusion: Deku must have begged the UA staff to let him still be in school while in heat to show he was strong even though he was an omega. Which is dumb. Staff must have let him if he promised to take suppressants and wear scent patches. Deku did, though he lacks self-preservation in all forms so he did not take a break even when he was in great pain from being at the peak of his heat. He must have passed out from overwork when he was in an extremely weak state. Stupid, stupid, stupid.
Aizawa-sensei cleared his throat, "Alright, there's not much we can do for him now. Since he's emitting so much pheromones we can not send him home right now with a good conscience so you problem children will have to take care of him while he goes through this. That, or lock him in his room."
Class 1-A shivered, they would never do that to their precious omega.
Aizawa continued, "I recommend you keep alphas away from Izuku for right now. We do not want any alphas going into rut by accident. So unless the alpha is highly trained, keep them away at all costs. Notify any other teacher besides me if you need anything. I will now be leaving the number one problem child to you."
Aizawa gently set Deku on the couch and patted his soft green curls fondly.
One thing everyone should know about class 1-A is they were very protective of each other.
After five seconds of just standing there stunned, Yaomomo, Shouto, and Katsuki were all practically being shoved out of the common room because they were the only alphas present. The only other alphas in the class were Shinsou and Tenya.
Shouto had practically begged -like the lovesick puppy he is- to Ashido that they could do something. Ashido and a few other members of the Idiot Gang were guarding the entrances to the common room so Yaomomo, Shouto, and Katsuki wouldn't get in. Though, Ashido was the only one who wore a black suit and sunglasses and cosplayed
like a very serious cliché bodyguard from any show.
After ten minutes of bickering between Ashido and Shouto, she finally told him that he, Yaomomo, and Katsuki could go shopping for Deku to get anything he might need while in heat. Katsuki internally cheered. The catch was that they had to bring a few betas from the class.
After more arguing, they settled on bringing Hagakure, Aoyama, Satou, and Shouji with them.
By eleven o'clock, the shopping group was off on their journey to spoil Deku rotten.
Maybe Katsuki didn't get to cuddle Deku and comfort him while he was in heat, but getting to buy him pillows, blankets, jackets, and stuffed animals for his nest was almost as good. Also, Yaomomo, Shouto, and Katsuki got to see Hagakure, Aoyama, Satou, and Shouji's jaw drop as they effortlessly spent probably over a thousand dollars. Perks of coming from a rich family, Katsuki thinks.
Hagakure muttered, "Sugar daddies," to Katsuki as Shouto and Yaomomo argued over who was gonna buy all the stuff. It was backwards though, they were arguing over who was going to buy it because they didn't want to, they both wanted to be the one to impress Deku by showing him they were rich.
Katsuki tried to punch Hagakure but she dodged, giggling. Katsuki growled and swung again, Hagakure began laughing her pretty little head off and ran away. Katsuki chased her down the isles of the store.
It took Yaomomo and Shouto half an hour at the register to figure out they could split the cost, which they ended up doing.
Then the group of seven got politely kicked out of the store.
"Um, guys, don't you think that's a little much?" Ashido said, eyeing the abundant amount of reusable bags they all carried. The bags held the aftermath of their shopping spree. They got everything they could think of. Blankets, pillows, stuffed animals, snacks, etcetera. Anything to make Deku happy.
"Got a problem with that, Pinky?" Katsuki said menacingly.
When they had entered the UA building the betas had immediately ditched them, leaving Yaomomo, Shouto, and Katsuki to carry the twenty-one bags. There was absolutely no way that they would be able to carry those in one trip no matter how much hero training they all collectively did. Their arms just weren't big enough.
"No?" Ashido said.
"Yeah, do you think Izuku shouldn't be spoiled after all he does for us?" Shouto said, flaring up his scary alpha pheromones.
"Definitely not. Izu-baby deserves the world." Ashido said.
"Then can we go visit Deku now?" Katsuki said, hoping she'd accidentally say yes.
"No." Ashido said.
Dammit, mission failed.
Shouto sniffed the air, then scrunched his nose cutely, "Is Shinsou down here?"
Ashido scowled, "Yeah, he attacked my poor Denki when we refused to let him see Izuku. Stupid alpha."
"Curious, Shinsou's usually not down until four in the afternoon on weekends, what changed?" Yaomomo inquired.
"He said something about sensing Izuku's horny pheromones and came down to see what was the matter," Ashido told the trio.
"So then what happened, did he just leave?" Shouto asked.
Ashido looked up at Shouto, "Nah, Aizawa-sensei heard the ruckus and came down to see what was the matter. Shinsou begged Aizawa-sensei and Aizwa finally let up, but we had to be on extra guard, watching those two at every second. It was odd, I think Shinsou and Izuku have something going on between each other. Aizawa obviously knew."
Katsuki paused, "Wait, so are you saying Mind Fuck is with Deku right now?"
Ashido frowned, "Yeah, weren't you listening?"
Shouto looked a little alarmed, "But it's dangerous for alphas to be around omegas during heat. They are in a weak and submissive state. Shinsou might try to take advantage-"
Ashido rolled her eyes, "Do you really think that lowly of Shinsou? Plus, alphas scents can be comforting to omegas at any time really." Ashido glanced backward, "I think it's really helping. Izuku looks less crazed now."
Shouto pouted, "Then why couldn't Katsuki and I have helped earlier?"
"And me-" Yaomomo added.
"Because-" Ashido looked left then right as if to see if anyone was listening in. "You didn't hear it from me, but I think Shinsou and Izuku are a thing."
"What do you mean?" Shouto asked.
Ashido rolled her eyes, "I mean, Shinsou and Izuku are dating." Then she paused, "That's one of my theories at least, it explains all their behavior around each other."
"That can't be," Katsuki denied.
Ashido gave him a look.
"What?" Katsuki asked, exasperated.
"You know what I mean."
Yeah. He did. Ashido was trying to tell him to let Deku go and go after Shouto who she thought he had a better chance with. Definitely not true.
Katsuki sighed, "Yeah, I do."
"Then do it," Ashido suggested.
Katsuki shook his head.
Shouto looked positively confused. "What am I missing?"
"None of your fucking business, Candy Cane," Katsuki said with no malice.
"Look, I'll let you three in as long as you promise not to attack Shinsou. Even though he deserves it for attacking Denki," Ashido offered.
All three of them nodded quickly in agreement.
The three stumbled into the room in a rush. Katsuki didn't know what to feel at the sight before him.
Shinsou and Deku were snuggled up to each other. Deku's hands were wandering underneath the purplette's shirt, but Katsuki chalked that up to being delirious from the heat. Besides, Shinsou looked absolutely fine and consenting toward it. Katsuki even dared to think, Shinsou looked more than happy about it, he looked like he was enjoying it. Little shit. Definitely had a crush on Deku. They were both huddled under a mountain of blankets, pressed up against each other.
Katsuki watched as Deku leaned into Shinsou, going in for a passionate kiss. Shinsou blocked it with his hand. Katsuki couldn't help but respect Shinsou for that. He didn't lose control and give into the pheromones Deku was emitting that were just begging to be bred.
Shinsou took his hand off Deku's mouth and whispered something in the greenette's ear. Deku turned cherry red and Shinsou just smirked. What the fuck did that asshole say to his Deku!? He was going to murder Shinsou.
Katsuki pushed down those thoughts, knowing it was just his alpha going wild in the presence of an omega had romantic feelings for. Also, he knew Deku was not his. Deku was his own person. Katsuki needed to get control of his thoughts or the Idiot Gang was going to throw him in horny jail. He shook his head, clearing his thoughts.
All of this happened within five seconds and time seemed to unfreeze and Yaomomo was running up to Deku. She kneeled before his spot on the couch.
"Midoriya, are you okay?! Do you need anything? Do you want Shinsou away from you?" Yaomomo said in one frantic breath.
Shinsou tightened his grip on Deku and growled at Yaomomo, probably seeing her as a threat at the moment.
Deku just shook his head and squeezed Shinsou back. He tucked his head into the side of Shinsou's neck. He practically melted into the purplette. He mewled happily.
Katsuki couldn't help but be jealous.
Shinsou, sensing the jealous alpha pheromones, looked up. His head snapped over to the pair of male alphas near the doorway to the currently horny pheromone infested common room. He glared at the pair, "What are they doing here?"
Shouto looked offended, "We're not going to hurt you." His hands were up like a criminal to a cop.
"Yeah, but you might steal my ome-" Shinsou was cut off by a sudden pain-filled moan. Or maybe it was pleasure? It was kinda hard to tell. It could possibly be a mix?
Shinsou turned back around quickly to face Deku who had uttered the noise. There was a new surge of strong pheromones coming from Deku. This time more needy and urgent than horny. Shinsou gave Deku a concerned look and scooped the boy up, planting a kiss on the greenetttes's forehead. Izuku was like a doll now, unable to move. That must mean the heat would be over in at most five hours? At least, the worst of the heat would be over. Katsuki really needs to do more research on the study of heats.
The Idiot Gang was crowding the omega and alphas.
Hanta spoke up, "Um, do you think we should contact Aizawa-sensei?"
Ashido grimaced, "Yeah, probably. I hope he doesn't give us hell for letting you guys in here. I know you three just wanted to help."
Eijiro was already calling Aizawa by the time Raccoon Eyes said that. They heard only what Eijiro was saying.
The line picked up on the second ring, Aizwa spoke first but Eijiro responded wincing, "Um, Izuku is in the last stage of his heat. We think it might be best for you to pick him up now." Pause. "Thanks." Pause. "...no?" Pause. "Um, yes." Pause. "We might have let Shouto, Katsuki, and Yaomomo in." Pause. "Because they asked?" Pause. "Yes, sensei." Pause followed by a grimace from Eijiro. "Yes, sensei." Eijiro ended the call. Then he asked the group, "Average news or bad news first?"
"No good news?" Denki asked, pouting.
"Nah, I'll just tell you the average news first: Aizawa is coming to pick Izuku up any minute now," Eijiro said..
"What's the bad news?" Ashido asked, sounding like she already knew.
"Extra of every exercise next class," Eijiro responded.
