He remembered the first day they met. Apparently, from the diaries, she saved him from some bullies back when they were younger. He couldn't exactly remember the exact words from her text, or the exact details, but he could picture it clearly. Even when young, her mother gave her a diary for her to write about her life, everyday in order to keep memories. Over time, as he read more and more, this memory would be repeated over and over in the years of text she wrote, each story evolving more and more in detail until he could play out the whole scene in his head. 

Even though he didn't remember all of it, being over twenty-five or twenty-six years ago, but he remembered at that youthful age, everybody thought his quirk had formed late; some thought that he didn't have a quirk at all. Often, boys who had their quirks already would constantly pick on him. He remembered that. No one at that point knew that his quirk was that he could erase others; it wasn't something that could exactly be seen to have been developed. Some boys had horns or tails forming, others had different changes in their bodies. He didn't have any physical changes to himself, so his parents assumed his quirk was developed late or he was quirkless.

He also remembered her. She was a new student at Sarugaku Elementary school, arriving a day after the first. Her h/l h/c was the first thing he noticed, then those gleaming e/c eyes, that shone brighter than anything else he had ever seen. With a frilly, pink little dress, she stuttered as the teacher told her to introduce herself, looking down at her feet and fidgeting with her hands from behind her. Her quiet whisper could only be heard from the front seats, and luckily he was in one of the front seats, so he was able to hear it. 

He remembered her words. 

"Er... hewwo... m-my name's Y-Y/N... L/N... i-i-it's nice t-to m-meet you." 

At first, he raised his eyebrows, deciding for now he should focus on something else. 

During the next week at lunch time was when they both had officially met.

Two older boys came up to the young Aizawa as he sat down on the bench in the small playground the school owned. 

"Hello?"

"Hey! What's your Quirk?" one of the boys approached him, smirking as they looked down on him with more malice and evil a six-year-old should be able to obtain. 

"Uh... I don't know yet," he answered honestly. He wasn't aware yet of the consequences of not having a noticeable Quirk. 

"So are you Quirkless?"

"I don't know. I guess so. What are your guys Quirk?"

"Sorry, we don't talk to Quirkless losers." 

"I just wanted to know what your Quirk was..."

"You want to know what our Quirk is? How about we show him?" 

One of them, he remembered, had a quirk of materialization, and as soon as his fingers touched ground, a hole started to emerge from the bottom of one of his feet, making him sink a few inches or so, but still, he couldn't move the captured and immobilized foot. 

"What do you think, Mota?" he smirked as he looked up from the ground with his fingers still planted in the ground.

"It's Shota!" he argued back, not entirely impressed. If he really tried, he could pull out, as the ground had attached itself to his foot. 

The other boy growled frustratingly, and pushed the young ravenette back onto the floor. "Hey! What was that for!"

"We don't like Quirkless kids!"

"I'm the same age as you!" he snapped back, attempting to get back up, until he got slapped by the boy, making him tumble back.

Aizawa yelled back in frustration rather than pain or anger, the impact hadn't hurt him at all, but after a few seconds, his cheek started to sting, becoming incredibly painful, more painful than what he should have felt even if he was slapped at full force. "Ow, what the flip!" 

"The doctor said my quirk is called "Aftermath," whatever that means. Do you like it?"

"Ow! No, get away!" the young male whined, placing a hand on his reddened cheek, as he sat up to them gazing down at him. 

"No way loser! Mommy told me that we're better than everybody and that means you!"

"Go away! I didn't do anything to you!" 

"H-hey! W-what are you doing!" a femine voice heard from behind them.

"What do you want? Go play with your friends! Oh wait, you don't have any!" 

"I don't care! What are you doing to Aizawa?" 

"Nothing! Go back to your books, nerd!" 

"Hey! I said, "What are you doing to Aizawa!""

"Go somewhere else! Why do you care for him? Is he your boyfriend?"

"Stop it! Go away or I'll make you go to sleep!"

"Ha! Fine then, make me go to sleep." 

She walked over to him, and placed her hands on his shoulders, keeping them still for a few minutes before mumbling "Go to sleep, go to sleep, go to sleep..." 

Then, the boy collapsed, leaving the other male with the one who had his fingers attached to the floor, screamed and let go, making the hole Aizawa's foot was in, rising back into the proper height. 

"Ahhh! Teacher, teacher, Y/N-" the other boy ran away, leaving Aizawa and Y/N to themselves.

"Hey, you okay Aizawa?"

He stared at her, marvelling the distinct features of her, lost in her e/c pits, until he snapped out, mentally slapping himself. "Uhh... yeah. Thank you Y/N. What about... you know... him?" 

"Oh, he'll wake up in a few minutes. Hehe, I guess that makes me your hero!" she replied, smiling brightly at the sulking child, her radiance nearly blinding him as he cocked his head in confusion.

"Huh?"

"Oh, I thought you liked heroes. I accidentally peaked at your All About Me paper, sorry, sorry!"she apologized, clenching her fists tightly in anxiety.

He grinned. 

"Yeah, I do. I guess that does make you my hero. Next time, I'll be your hero, I'll make sure of it!" 

His back snapped forward as he sat upright, immediately regretting it, a pain forming at his spine, and he winced from the back pain. 

"God, fuck..." he muttered under his breathe, moving his arm to his back to soothe the hurting.

"Why do I keep having these dreams?" his voice whispered in the comforting silence of his bedroom. 

Brushing his hand against his forehead and wiping off some sweat, he calmed down his breathing thinking back to the memory. 

"Tch, some hero I was."

A/N: Alright, so this is a memory of when they first met. I honestly had way too much writing the fluff. I love Y/N's and Aizawa's interaction. What about you guys?
