M-Side (Part 1)

On Midoriya Inko and Yagi Toshinori's wedding day, they had 2 ring bearers. One was Inko's son, Midoriya Izuku, and the other one was the child of Inko's matron of honor.

His name is Bakugo Katsuki. Katsuki had blond spiky hair as if his hair was electrocuted and permanently gelled to stand, with a pair of complimenting menacing scarlet red eyes, at least, as menacing as an 8-year-old kid could muster. It was the first time Izuku met him but the other ring bearer already hated Izuku so so much.

The first time they met, it was at the wedding rehearsal.

"I can do this by myself!" He declared gruffly upon being informed that he was not the only one assigned the task. Traditionally, you only need one ring bearer after all.

"Izuku can do it by himself," Bakugo Mitsuki, Katsuki's mother as well as Inko's matron of honor, corrected. "He's actually been doing it by himself ever since the rehearsal because you're too lazy to show up for the briefing." Kaachan crosses his arms, pouting. "The only reason why you're there in the first place is that I thought it'd be cute if both you and her son would walk around the aisle with matching ring bearer uniforms like you're some color-coordinated best friends."

Both she and Inko swooned at the idea.

"Best fried?!" Katsuki scoffed, pointing an accusing finger at the curly top. "You think I would be friends with someone who looks as stupid as him?!"

"Katuki!" Mitsuki shouted, slapping the back of her son's head.

"What the hell?!" He shouted back.

"Language!" Mitsuki admonished, what she didn't know was this was her son's tamed version of speaking. It'll get much worse in the future.

"It's okay," Izuku finally spoke, emerging behind his mom's legs. "I get that a lot. Okaa-san," He softly pulled his mother's wedding gown, trying to catch her attention. "I don't mind if Mitsuki-obaasan's son takes my job. He'll be a better ring bearer than I ever will."

"No, you got it wrong." Mitsuki sweatdropped. "You're the son of the bride. You're needed there. Katsuki's the one we can remove. And Inko should because Katsuki didn't bother attending the rehearsals like he ought to." She added, glaring bloody murder at her son.

"But it's boring!" Katsuki whined.

"Izuku," Inko frowned and knelt down to Izuku's level, patting him on the head. "You'll be a great ring bearer."

"But I'm stupid and clumsy," Izuku looked down, small beads of tears trailing down his chubby cheeks. "My classmates said so."

"Izuku," Inko repeated, kissing Izuku's forehead. "Please trust yourself a little bit more."

"He's a timid child, isn't he?" Mitsuki smiled sadly. Katsuki looked up at his mom's face with an unreadable expression.

"Izuku apparently gets bullied in the grade school he studies in," Inko patted his son's bushy hair, wiping his tears with her other hand. "Mostly because of his dad... Or should I say, lack thereof."

"At least you have a new dad now!" Mitsuki knelt down, too, so that they can speak at eye level. "Aren't you happy you have a new dad?"

"I'm very happy," Izuku wiped his tears and his eyes immediately lightened up as soon as his new father was mentioned in the conversation. "I love All Might-san a lot!"

"He even calls Toshinori-san with his military moniker," Mitsuki giggled. "Don't worry, All Might-san will be a great dad and he'll never leave you!"

Izuku nodded with a grin, a few tears still trickling down his face.

"I'll help you," A small voice whispers from behind.

The three turned around to see a blushing Katsuki, tiny hands balled into a fist. "In case you trip, I'll catch you. I'll even make sure you won't lose the ring. So..." He turns a brighter shade of red. "... Don't cry."

Izuku knew that the only reason why he bothered to say that was because Katsuki made him cry in front of their mothers and Katsuki was sure Mitsuki will give him hell for it when they get home. But for some reason, he felt something warm and comforting welling up in his chest.

Izuku cried even more.

On the way down the aisle, Katsuki was holding a still-crying Izuku's hand. Inko still has pictures of that moment, and Midoriya thought it was hilarious to see Kaachan so red-faced as he fights the urge to throttle him just to stop him from crying.

"What's your name?"

Midoriya could still vividly remember how their conversation went as they crossed the aisle. Looking back, it was just a short trip. But to their small feet and short legs, it seemed like a pilgrimage of a lifetime.

"Izuku," He sobbed.

"Stop crying," This was the part caught in the picture and he looks like he wants to murder Izuku right there and there. "you're annoying, you're stupid and useless."

"What?"

"You can read your name as Deku, didn't you know that?"

'Deku' shakes his head.

"You really are useless," Katsuki muttered under his breath. "Because you're a stupid idiot," he said through gritted teeth, still holding Izuku's hand as they finished passing the rings to the bride and groom. "I've decided to hire you as my henchman, Deku."

Large green eyes widened at the nickname, a warmth from his belly swelling so much to the point it felt like it engulfed his whole being.

"Starting this day forward, no one will bully you but me." Katsuki gave him a sideward glance, offering a proud wide grin that will forever be etched to the back of Deku's mind. "Be grateful, you pathetic little shit."

Izuku nodded.

Once they were out of everyone's sight, he jumped at Kaachan and trapped him in the greatest bear hug his small frail arms could muster.

"Thank you, Kacchan!"

"K-K-K-Kacchan?!" Kaachan scoffed incredulously, trying his best to peel Deku's arms off of him. But to no success. "Get off of me!"

It was the day Izuku made a friend.
