Kirishima was training in the gym with Bakugo when something caught his eyes on the other alpha's neck. He got a bit closer, probably invading his personal space by accident, finally realising what it was: the scar left by a bite mark.

"Bro, did a villain tried to claim you or something?" he asked rather confused, making the blond turn towards him, also confused about what he was talking about. It took Kirishima pointing at his own neck for Bakugo to understand what he was talking about, a grin forming on his lips as fingers went to touch the mark.

Just thinking about it could make him smile.

Bakugo was standing in the kitchen, thinking about what he could do for breakfast, waiting for the coffee machine to finish its work. He turned back to where Midoriya was sitting on the couch with his notebook, most likely going over his notes, ready to call out to him. Yet, he stopped himself when he noticed something else: Midoriya was slowly running his finger over the scar on his neck, most likely without knowing it.

He had noticed him doing it for a little while now. When lost in thought, his mate would often start tracing over the scar left behind by his teeth. The mark was often hidden by his clothing, as it was rather low on his neck, but at home, it was often showing when he was stealing the blond's shirt. Bakugo had started to wonder why he would always touch it, sometimes a little worry setting in. Was he regretting it?

He made his way to the living room, sitting down next to his mate, the man leaning a bit towards him. Midoriya ended up giggling a bit when the alpha decided to lift him up and sit him in his laps, arms wrapped around his waist. He went to kiss the mark he left, another little giggle escaping Midoriya.

"Good morning to you too," said the omega, turning a little bit towards the alpha after setting down his notes. "Good morning" smiled the blond, his eyes turning back to the scar, trying to see if something was wrong with it. Maybe it was hurting him?

"is something wrong?" asked Midoriya with an arched brow, looking a bit amused by his staring. He hummed a bit, before looking back up at his face, "I was just wondering why you were always touching your bite mark, is it sore?".

The omega seemed a bit confused by his question, going to touch his neck again. "Do I touch it that often?" he asked a bit surprised to learn he was doing that. "I only noticed it recently" admitted Bakugo, "But you seem to trace it when you are lost in your thoughts" he explained. Which was rather often when he wasn't talking with him.

"Oh, I didn't notice" replied Midoriya, which was something the blond had figured. "But no, it's pretty much like any other scar, I don't feel it, it only hurt when it was first bitten there" he explained. Well, of course, it would hurt for a while at first, but it had already been years since Bakugo had bitten his flesh, now it was just there. Although sometimes it felt like the area around it was a bit more sensitive than others.

"So there's nothing wrong with it?" finally asked Bakugo, simply wanting to make sure. He received a nod, Midoriya looking a bit confused on the whys it could bother him. Yet, something seemed to pass in his mind, but he didn't say it, only making Bakugo frown a bit. "You thought of something, didn't you?".

Midoriya then gave him a small smile, a bit unsure whether or not he should voice his thought. "You will think it stupid," he said, only for Bakugo to arch a brow, trying to keep in the 'you often have stupid ideas' that wanted to get out. Not the time to argue about whether or not Midoriya had stupid idea sometimes.

"I was just thinking its a shame I cannot show it" he admitted, only for Bakugo to look confused. This made Midoriya blush a bit, knowing how stupid it was, especially when the alpha wasn't putting much interest in what many were interested in. "You know, some like to show off their mark when they have a great mate, or because the alpha wants to make their territory known" he explained.

But he couldn't really do that now, could he? The fact that he was an omega was still a secret kept from the public, he couldn't just show off his bond to Bakugo as if it was nothing. In the best-case scenario, people would think he was dating an alpha who wanted to claim him despite being a beta, worst case they would figure it out.

"You want to show off?" asked Bakugo, sounding a bit amused at the idea that Midoriya wanted to show off he had 'a great mate'. The omega simply blushed a bit more, before mumbling "Like this, people would know I'm yours and you are taken".

The blond was a bit dumbfounded. So this is what it was about? Midoriya wanted to show people that Bakugo was taken? He tried thinking about what he could have done or said that would have given the impression anyone was after him. The omega rolled his eyes a bit when he realised his mate had absolutely no idea what he was talking about.

"You are popular you know?" he pointed out, "People clearly wishes they could have you for themselves, even magazines are wondering if you are single and which omega will win over the great Dynamite" he explained. But of course, he wasn't expecting Bakugo to really notice this. Well, maybe he had notice people starting to be fans of him, which was good, but not the one who wished they were his mate.

The blond then seemed to think about it more, looking at his neck. The young man was starting to feel a bit anxious, wondering if what he had just said was truly just stupidity. Sure, it was useless to worry about something like this, he knew his Kacchan wouldn't go anywhere else. But it was still something he thought about sometimes when he would see headlines and post online.

He was taken out of his worries when he heard his mate gently chuckle, placing his head on his shoulder, smiling up at him. "Then why don't you mark me so everyone knows I'm already taken?" he suggested.

It was the time for Midoriya to be dumbfounded this time, wondering if he had really heard correctly. Yet, he realised it was indeed real, Bakugo was really offering to also be marked by his omega so everyone would know he was taken. For a moment he really thought he was hallucinating. "Are you sure?" he asked, not wanting for Bakugo to regret it later. "Wouldn't have suggested it if I wasn't sure".

Midoriya still thought it was quite sudden, yet there was something inside him wanting to do it. Like this, he knew others would know Bakugo was already with someone. Or at least let a doubt that he wasn't single. Maybe the media would go crazy over it once they figured it out, but right now he thought it wasn't a bad idea.

The blond then took him off of his laps, turning his back to his so he could have better access to his neck. The omega gently went a brushed his fingers against his neck, a hand joining his to guide his fingers. "You can do it here," he said, the fingers stopping rather high on his neck. "B-but this is really hard to hide" pointed out Midoriya.

The alpha hummed a bit, turning slightly towards him with a grin "I know, wasn't it what you wanted to do? Showing off? If you cannot show your bite mark, then I'll let everyone see mine".

Fingers started to slowly tremble a bit, not believing Bakugo would go this far for him. How had he managed to find a mate who didn't care about what an alpha 'was supposed to be', going as far as accepting to be marked by his omega? It was one thing scenting him sometime when he felt anxious about it, it was another literally biting his neck to leave a mark.

"But am not sure if my jaw will be strong enough" admitted Midoriya, despite wanting to do it, his body was probably not meant to be strong enough to easily bit down hard enough to leave a permanent scar. "Then you can try using your quirk" suggested the blond, "I know you won't just bite off my neck".

The omega was a bit unsure. Sure he had gotten good at controlling One For All, but it was still something he would rather never need to use on his friends and his mate. Yet Bakugo was there, neck uncovered, ready for him to use it like that.

Midoriya then got closer to him, gently reaching to grab one of his hand, squeezing a bit. "If it gets too much just release my hand, okay?" he asked. "Will do" replied Bakugo, knowing that if he didn't reply the young man would just keep being worried about it.

Then Midoriya bent down, leaving a light kiss where he was going to bite, leaving one last time for the blond to back out. Yet he was still tightly holding his hand, unmoving and rather relax despite what was to come. Such a stark difference from the rather anxious and tense state the omega had been when Bakugo marked him. Well, it was probably due to them being rather different in that department.

Without any objection and backing out, the omega finally used his quirk to make his jaw stronger, biting down on Bakugo's neck. He felt the hand grabbing his even more strongly, trembling from either the pain or by trying not to crush his. Once the omega felt it was deep enough to leave a permanent mark on his neck he released, trying not to hurt him more. He then kissed his neck again, the metallic taste in his mouth a bit strange knowing it wasn't his own blood this time.

Bakugo then turned back towards him, offering a satisfied smile. He then stole a kiss from his mate, licking away the blood that was still on his lips. "See, it wasn't that difficult, was it?" he teased a bit, not letting go of Midoriya's hand. The omega couldn't help but smile at how satisfied his mate was, no regret showing on his face. "Let's just take care of your new wound instead of mocking me" he laughed, standing up before trying to pull him up too.

With this the blond followed his mate, letting him take care of the bite, only then remembering to ask him what he wanted to eat for breakfast, other than him.

"It's a long story," said Bakugo with a smile, Kirishima now wanting even more to know what it was all about. "Let just say a little someone wanted to make sure people knew I am his" he laughed, "But this isn't the placed to talk about it".

Kirishima was rather impressed by how the two love-birds were. He really wanted to find someone with whom he could just throw out the window any expectation that was wanted of them and just do whatever pleased them.
