You didn't know who he was or what he did for a living. You just knew that he always came to your supermarket and he was always quite keen on buying groceries when the best sales occurred.

He intrigued you a lot but you always grew too shy to say anything other than the price of his groceries. It made you mad and everyday you tried to grow the courage to ask for his number or even a name but then suddenly his presence seemed to render you speechless.

The man had short black hair when you first saw him. He was pretty tall and had a good physique if you did say so yourself. Three years later he was now bald but that didn't stop you from becoming a blushing mess when he came to your register.

He used to come in a grey suit- his tie hanging loose around his neck like he had finished a boring day in the office. Nowadays he came in a yellow superhero suit or sometimes just casual clothing worn to go out.

The yellow suit made you think he was a superhero but the lack of remembrance to his face or, well, lack of a name made you think other wise. That day you actually felt bad having not noticed him.

It became a sort of unspoken routine between the two of you. You always saw his eyes light up immensely when something was discounted to a way lower price and so you wanted to give him a reason to keep coming into your checkout.

You slowly began scanning his items and then when you knew none of your co-workers were watching you would put some unscanned items in his bags- leaving them unpaid for and free.

The abnormally dropped price caught his attention but he merely shrugged and walked away with the receipt- checking it over to see some items not on the little piece of paper.

It gave him a tiny bit of excitement when he saw this and at first he actually thought you did it on accident. You heard him mutter, "Oi.." When he first noticed the reciept but you simply shushed him- replying a simple, "Your Welcome." And left him on his way.

It became a cycle- he comes in and went straight to you, he excitedly let you scan- and not- his groceries and the low prices made him actually throw a smile your way.
You would blush and smile back- feeling happy you got to do this for such a kind yet mysterious man.

You knew it was against the rules to do what you were doing and getting caught by your manager would definitely leave you jobless and without a source of income but you couldn't help it.

He was the highlight of your day and you wanted to know him better.

Weeks passed and he still came to your checkout when you were there and he waited to see what you would secretly pass without scanning and he would smirk in satisfaction, slight redness filling his cheeks. It was quite odd that he never questioned why you would do such a thing for such a simple looking guy that you didn't even know but if he didn't object then you would continue.

One day though, you were continuing on with your day at work like normal and you saw the man there with his basket filled his groceries on sale.
You were quietly standing in your checkout, again unable to take your eyes away from the bald man who squirmed his way into your heart and penetrated your mind. It annoyed you because it truly showed how much confidence you really lacked but all thoughts were cut short when screams were suddenly heard outside.

The ground began shaking- almost like it was vibrations caused by someones huge footsteps and you looked around- wide eyed, watching everyone- customers and workers- run out of the store screaming. You were still as you wordlessly watched the bald man mess with his coins in front of you while this was all happening.

You wanted to warn him to get out and save himself but the lack of any emotion or reaction at all slightly scared you.

And then in the blink of an eye the whole roof was ripped off of the building- you gasped, tears stinging your eyes thinking about another monster was coming to terrorise you before it killed you like the rest of it's victims. You covered you head, crouching and somehow managing to protect yourself from the debris when you heard his voice, directed at you.

"Oi.. You okay?" He simply scratched his head and didn't give you any time to answer when you only feebly nodded and he smiled at you gently before leaping into the air towards a massive giant who was stomping and destroying all of City B.

You cried out to him, wanting him to be okay and not die. You couldn't believe he actually flew onto that thing and stood on his shoulder like it was nothing. The monster stood hundreds of metres tall and on his shoulders you could hear a normal sized man yelling something about 'Biceps King.'

You watched as the man began yelling towards the bald man you hoped wouldn't be led to his death and then the giant swiped his hand onto his shoulder- killing one of them. Only the giant had killed the man that wasn't the superhero you were watching.

The giant saw his mistake and began yelling in agony about killing his brother and how he was the strongest man- only know he was weaker and empty without his brother.
So the man he had killed was his brother and now he was going on a rampage.

The caped bald man who you still hated not knowing the true name of had finally had enough after taking a look at the damage done to the city. He swung his red gloved fist into the giant monster face killing him.

With just one punch..

Your jaw dropped when you watched the monster die so easily. How did you not know this hero? You had to know his name- how could a simple man like him just come out of nowhere and kill a giant monster on steroids like that.

Shaking your head from the dizziness of your loud and racing thoughts- you didn't even notice the man who just saved your life was back on the grown offering a gloved hand in your direction.

He smiled again, not saying anything as you finally got off of the ground and awkwardly held his hand before you quickly and forcibly pulled him to you and hugged him. You could tell by the quiet gasp and the way his body became stiff that it surprised him.

You eyes went wide again when you realised what you did and you were about to back away before you felt his two strong arms wrap around your waist and hold you tighter into his embrace.

Minutes later you both let go of each other, avoiding eye contact even though the both of you were now a blushing mess. You nervously used your left hand to move some hair behind your ear while your right hand went out towards him. You let out a shaky- and awkward- laugh as you finally introduced yourself, smiling widely- thinking about the terrible circumstances of your belated formal meeting.

"I'm (Y/N) (L/N)."

In return the man looked at your hand, seconds passed when he registered what was happening and he gently shook your hand, introducing himself in return.

"Saitama- Hero for fun."

You chuckled and just when you were going to let go of his hand to go home, a tug on your arm got your attention- his grip tightening as if he didn't want you to leave.

You looked back into his eyes and saw him looking puzzled like he was having a battle with himself in his mind while looking down but then finally looked up and gave a toothless smile.

"Oi, Let's go get dinner- my treat for all those free groceries."

You blushed in embarrassment, thinking about all those times you were too shy to speak and found yourself nodding in no time- wanting to get to know him more.

And him wanting to know why he was suddenly feeling something again every time he looked at your face.
