Katsuki Bakugou 

What is he doing? Bakugou watched as Izuku fumbled for his words. He was sitting in Bakugou's bed, wrapped in his blankets. His green curls were messy and framed his face perfectly. Bakugou couldn't help to think he was quite beautiful in his own stupid way. When Izuku passed out in the arcade, Bakugou thought it was his heat hitting again. Although it was passed almost 2 weeks ago, the thought scared him. He hated the thought of the omega being in pain, and even worse, the thought of him not being able to control himself around this specific omega in heat. When Bakugou sniffed the air, realizing no scents were coming from the boy, it only brought more concern. Bakugou kept a cool face, and went to the boy's side. He carried Izuku to the car, drove his group back to school, and carried Izuku to Bakugou's room. He normally would have taken him back to his own room, but he wanted to know what the hell was going on. It is not like Izuku to pass out randomly, he had never seen this happen before. What made it all worse, he could not smell Izuku. There was no crisp apple scent, just the faint smell of his shampoo. 

Bakugou snapped out of it when he heard Izuku speaking.

"E-Ever since we stopped scenting and stuff, and we agreed to let the scent mark fade... I have been feeling really... um... lonely is the only word that seems to fit the feeling. Like, I can't focus on things and I j-just wanna be c-close to you...."

Bakugou watched the stuttering boy in his bed. His face was red, but that is normal, Deku always blushes. Suddenly, Izuku's words came crashing down on him. Izuku felt lonely since we stopped scenting? That is normal. Izuku wanted to be around Bakugou and close to  him? That is also normal. Bakugou knew all these things, but how come Deku was so ignorant about this topic? He had been given education on this stuff right? Bakugou's mind wandered around and he finally knew what Izuku was asking. He wanted to know if Bakugou missed him too. The fucked up part is that he did. He missed being around the shitty nerd a lot. But he knew it was because of the scent mark, and that Izuku had his heat while being claimed by him, but did not get to spend his heat with the alpha that claimed him. It was a really rough time for an omega and to basically have been claimed and then ripped away from the other person, that could cause really bad feelings and depression. 

Izuku was finally healing though. It had been 5 days since the two decided to let the scent fade. They just needed to make it a couple more days and then things should go back to normal. Bakugou needed to be strong for Izuku, it was his fault for being so irresponsible and claiming him in that vulnerable state. Bakugou had to lie. As much as he wanted to run up and scent the sad boy, calming him down like they did all those years ago as children, he knew he couldn't. Izuku did not want a relationship with Bakugou, and if he did, Bakugou knew he would be a shitty partner. It's best to just rip the bandage off fast. So, that it what he did.

Through gritted teeth, he shot a cold glare at the boy sitting in his bed.

"No, I haven't felt anything like that." Bakugou growled and turned away. He had to get out of here, fast. A burning feeling lit in his stomach and he grabbed his shoes and ran out of the room, leaving Deku alone and probably confused. He needed to get out of here. Bakugou threw his shoes on and decided to go on a run. Running always seemed to help ease his mind, but this time, he knew it wouldn't help much. The truth is, Bakugou was feeling just as lonely. Like something had been taken away form him. He knew he did not own Izuku, he isn't gay and he doesn't even have feelings for Izuku like that. Sure, he wanted to be close to him but it is just because Bakugou is an alpha and Izuku just so happens to be an omega. Fucking biology. Alphas and omegas are literally made to be together. His body was reacting to the boy without him even really knowing it. 

Bakugou had never really been interested in girls or dating. He had kissed a few girls in high school and middle school but never really was into it. He met a few omega girls as well, sure their scent was enticing but again, it never really ticked all his biological boxes. It freaked him out to no end when he reacted so strongly to Izuku. He kissed him and was basically rutting him like a dog in heat. The thought made him want to puke. Izuku used to be his best friend and he ruined that by being a complete dick to him after presenting as an alpha. He couldn't really help it though. His hormones were all over the place, his alpha instinct telling him to take charge, dominate, and overpower any weaker thing around. He had felt out of control of his body for a good 2 years until he started to have better schooling targeted to alphas. But, by then the damage was done and him and Izuku had stopped talking.

Bakugou ran laps out in the running track for about an hour. He had worked up a good sweat and decided to go back inside for a shower. Deku was probably gone by then. Bakugou avoided the group of pestering teens in the lobby that kept asking how Izuku was doing and just rolled his eyes, making his way to the elevator. After a few seconds the door opened to his floor and Bakugou ran his hands through his sweaty hair before unlocking his door and heading towards the bathroom. 

"K-Kacchan..." A scratchy voice called. Bakugou snapped around, shock covering his face. It was Deku, still sitting in his bed. His eyes were puffy and red. Had he been crying? Bakugou stood still and watched the boy. 

"What are you still doing in here?" Bakugou finally said and he watched as Izuku hung his head. Small chocked out sobs were sounding from under that mop of green curls. Bakugou stood stiff as a rail and watched Izuku like a hawk. What the hell is going on here?

"K-Kacchan.... remember when we were kids and when someone was mean to me you would hold me and make it all go away? R-remember you w-would take care of m-me? K-Kacchan p-please, c-can you m-make it go away?" The younger boy sobbed and Bakugou was not moving. His heart was beating a million times minute.

A louder sob broke through Izuku's chest and it broke Bakugou's heart. He felt anger rise up in his chest. Anger for making his childhood friend cry. Anger for not being able to move his stupid body forward and comfort the boy. Anger for being so cold to him during this time.

"Deku... We can't do that. We are trying to get our scents off each other remember?" Bakugou said through gritted teeth. He did not want to hurt the boy's feelings, but he also wanted to fix what he had done. Another sob racked through Izuku's body and Bakugou flinched.

"P-please K-Kacchan, I can't take it anymore. I f-feel so empty. I-I don't care about the scent, s-scent mark m-me again!" Izuku exclaimed and looked up at Bakugou. His green eyes were shining from his tears and he looked so broken. Bakugou was dumbfounded. Izuku wanted him to scent mark him again? Why was this being such a hard thing for the alpha to comprehend? The two boys used to cuddle and rub scent glands all the time. It was a comforting habit they two had made up after seeing their parents do it all the time. Their parents even made jokes about how they were going to make their future mates very jealous with how close the two boys were and how their scents would always be all over each other. A few moments passed and Bakugou felt like he was going to either cry or scream. He raked his fingers through his messy hair and let out a sigh. Izuku heard and looked at the alpha through his wet eyelashes.

"K-Kacchan..." Izuku said, almost begging. Bakugou snapped and moved. His body taking over, Bakugou climbed in bed and pulled the green eyed mess into his lap, forcing Deku to straddle Bakugou's lap. Bakugou still could not smell Izuku and it frustrated him to no end. Izuku let a little gasp put before he quickly clung to the alpha's shirt and nuzzled his tear stained face into the nape of Bakugou's neck.

Bakugou brought his hand up and hooked it around the back of Izuku's neck, holding his head against his neck. The alpha released some of his scent and a small mewl broke out of Izuku's lips. Since Izuku was on his suppressants, he could not release any of his own scent but Bakugou still pulled on his neck making Izuku tilt his head to the side, giving better access to the alpha. Bakugou hummed as he rubbed his neck against Izuku's, causing a purr to rumble in Izuku's chest. Since Izuku could not release his scent for the alpha, he chose to purr. Purring was evolved by omegas to help comfort their mates and show gratitude. As he purred, he could feel the alpha under him start to relax. Bakugou started to softly run his fingers through the younger boy's hair, earning soft keens and purrs to bubble out of the boy. After a while, the sounds stopped and Bakugou guessed that he had fallen asleep. Trying not to wake him, Bakugou wrapped his arm around the boys waist and turned their bodies so they were laying chest to chest on their sides. Izuku nuzzled up to the alpha before going still again.

Bakugou rolled his eyes and pulled the covers over their bodies before trying to go to sleep himself. His mind was buzzing with questions. He was confused and had no idea why Izuku was so upset, but he could not refuse the crying omega of the affection he was desperately seeking. He also felt super uncomfortable that Bakugou gave in and scented the boy again. He is a strong alpha, why could he not get his shit together? Now this is going to be even more of a hassle to let this scent mark fade away. Bakugou was sure that Izuku did not mean what he said about not caring about the scent mark. Izuku would find a mate and then be really upset that he had been scented by Bakugou already. If Izuku wanted a mate, then he would have refused the scent mark. Bakugou had never really thought about finding a mate before, so it did not bother him to have omega scent on him.

Bakugou listed to the soft snores of the sleeping boy beside him and felt a calmness fall over him. Something about this felt right, and it scared the alpha. Here he is, cuddling the boy he had once called his best friend, but then had turned cold towards. Something felt wrong but so right about all of this. Bakugou just needed time to figure out what it was, but for now, he will enjoy the familiar feeling of having his best friend back, even if it is just for tonight.

Izuku Midoriya

It was warm and smelt so good. A soft flutter was felt against his neck and made him smile, it tickled. An orange light was shining in the room and Izuku slowly opened his eyes. The first thing he saw was messy blonde hair next to him. Upon realizing who that hair belonged to, Izuku's eyes widened and his face flushed with color. He tried to move, but strong arms are locked around his waist. Bakugou's face was pushed into Izuku's neck, soft puffs of breath tickling his skin. All of the previous night's events came flooding back into his brain.

After Bakugou had left the room suddenly, when Izuku had asked about the lonely feeling, Izuku fell apart. He cried for what felt like hours until he fell asleep, hugging Kacchan's pillow because it smelt like him. He remembers Bakugou coming back in and being startled to see Izuku still in his room. The next part was a flood of embarrassment. He spewed his guts to Bakugou an practically begged him to scent him again. Izuku felt his face heat up and he internally screamed before trying to calm himself. He noticed a faint scent of apples in the air. Oh right, he didn't take his suppressants last night. He also noticed his distress pheromones were being released and then the sleeping alpha next to him must have smelt them. He let a low rumble spill from his lips before pressing his face more into the omega's neck. Izuku's eyes widened and he felt the calming pheromones of the alpha start to seep into his pores. His body instantly relaxing as if on command. 

Izuku did not regret what he did. If it was that bad, Bakugou would not be here sleeping next to him. Bakugou would have blasted him and told him to get out, but he didn't. A small smile pulled at his lips and he reached over, gently running his fingers through the alpha's messy blonde locks. Izuku's eyes trailed over the sleeping face in front of him and he smiled before turning his head and nuzzling his nose into the alphas hair, breathing in that familiar scent of his best friend.

"What are you doing, nerd?" A gruff and sleep filled voice muttered against Izuku's neck.

Oh God.
