Tatsumaki had faced some tough battles and had nearly lost her life, so why was she so stressed about her new relationship?

It had been two days since their kiss, and she was so worried that she would mess this amazing thing up. She was more stressed about it than she had ever been, she felt wonderful, like a weight was lifted off her chest, she was so afraid of losing that feeling.

She shrugged it off, no matter what people thought or said, she would stay with him, she refused to mess this up. She had faced harder tasks, this was child's play.

So why did she feel so sick to her stomach? She knew she was finally in love, she needed this, she needed to stay calm.

She would go over to his house, get more comfortable with him, and it would work out. She just had a feeling.

She decided to just look comfy and casual, she wore a green hoodie, a skirt, and some basic white running shoes. And then she left.

She flew over to his place in city z, she wished he was closer, but she would go across that distance to see him. She got there pretty quickly, only a half hour considering the distance, she landed on the outside of his door, and knocked as she pulled her hair back into a ponytail.

Genos answered, and let her in when Saitama smiled and saw who it was.

He was on his floor, elbows on his knees as he sat crossed legged on the floor playing video games. She just grabbed the other controller, sat on his lap and played with him

The two silently played against each other until they got up to go eat.

Saitama made two sandwiches, he ate one while tatsumaki ate the other.

Genos looked at her funny, he clearly had no idea what went on between the two yet, so she smirked and decided to have a little fun.

When they finished eating, she made sure genos was looking before she approached Saitama.

"Thanks for the food." She said before pulling him down for a sweet kiss.

Genos's jaw nearly went slack from surprise, he turned away and went back to putting away dishes. He nearly broke them from rage, he barely had any self control not to crush them in his hands.

She noticed that and smiled, her suspicion was right, he had feelings for Saitama, but he couldn't have him.

He was hers, and he seemed content with her.

"Well, that's wasn't necessary, but I'm also not complaining." Saitama said jokingly as the two pulled away.

Genos nearly whipped a cup at the wall hearing his sensei say he enjoyed kissing another woman.

"Well, I felt like it." Tatsumaki said before she walked over to his couch and noticed the mail bag.

"Lets open this up." Saitama said, opening up the first letter addressed to him.

It read:

YOU STUPID FOOL

NOOBODY CARES ABOUT YOU

WHY DO YOU EVEN BE A HERO

YOU CAN JUST DIE AND NO ONE WILL MISS YOU

"This guy put in some effort in, definitely." He said before tossing the letter to the side.

Tatsumaki was stunned, he took that kind of hate and didn't even flinch, he didn't even acknowledge it. Whenever that happened to her, she usually boiled with rage.

Looks like she could learn from him.

Genos joined them and read his mail, he as usual got nothing but fan mail.

The next one Saitama got was a A-Rank Promotion, he was now A-Rank 84

Tatsumaki congratulated him and genos gave praise too, although the bald hero couldn't seem to care less really.

Saitama got mostly hate, but he had begun to receive some very kind letters. They were mostly of people saying thank you for saving them at some given point, some were just people who saw him fight.

He seemed pleased from the change of some people's hearts.

Tatsumaki was disgusted by how Much hate he got, but at least not everyone was a complete prick to her boyfriend at least.

The two read through their letters pretty fast and were done and over with, so Saitama went to his room with Tatsumaki following him inside his room.

He went over to his drawer and sorted a few things.

"Baka! Aren't you gonna lay with me?" She said from behind him in her usual tsundere fashion.

He turned and saw her laying on his bed on her side looking up at him.

"Sure, if you want." He said, laying next to her, wrapping one arm around her belly from behind and the other hand stroking her hair.

She snuggled deeper into him, turning around and putting her head on his chest and smiling into him, she could just be held like that forever.

"Hey." He said.

She looked up at the man and was surprised when HE was the one that leaned in to kiss her.

She closed her eyes and held onto him, savoring the touch of his lips on hers, as he wrapped his arms around her waist, pulling her in tighter. She wanted to just kiss him forever, never having felt his way about anyone until that point.

How foolish, she thought, she used to underestimate this man, the one that made her fall in love with him in the span of 2 days.

She was always so strong and so firm, and was cold and insulting to everyone, including her comrades and even her own sister fubuki. But she had opened her heart and become so warm to him.

She wanted him, oh she wanted him so much, she never wanted to let go.

He moved so that he was on top of her, he had one arm framing her head, and the other on her side.

She ran her arms up and down his back, and made small noises and bit her lip as he left little kisses all up and down her neck.

With a spark of bravery and curiosity, she began to lift his shirt, to which he promptly grabbed from her hands and took it off, exposing his chest and arms and all his muscles.

She nearly drooled at how hot he was really, he may be bald, but he had one hell of a body and really knew how to use his lips. She was his first kiss, but he seemed to master it already.

She guided his mouth back to hers and kissed him again, running her arms up and down his bare back as she kissed him more firmly, she reache-

"Sensei, you forgot a letter on the tabl-" Genos said before he saw what they were doing.

She wanted to rip him to pieces, did it even occur to him to knock first!?

"Damn it you Blonde Fool! We were having a moment and you fucked it up! Good going you asshole! Now the moments ruined!" She yelled at him as she sat up, absolutely fuming.

Saitama sighed, "just give it to me and leave the room." He told genos as he sat back against his wall.

Genos awkwardly handed him the letter and left, closing the door on the way out.

"I swear to god, I'm gonna kill him someday." She said, still extremely angry that her moment had been stolen by that dense fool.

"He might be an idiot, but he's harmless most times." Saitama simply responded, reaching for his shirt.

"Wait! I like it when you have your shirt off." Tatsumaki said, stopping him.

"See something you like?" He said with a small laugh, flexing his chest, abs and arms.

"I do actually." She said smiling as she climbed onto his lap and traced his chest with her finger, feeling the lines of his chest and ripped abs.

For someone so strong, he was surprisingly skinny. She thought it matched him though, the muscular frame without making him grotesquely large like some other S-Class heroes she worked with.

She pressed into him, almost sad that she knew she couldn't initate another moment like that, that was something that even she was caught off guard by.

Well, no use whining about it, she would just have to make the best out of what she could do.

"You know I love you right?" He said to her.

She widened her eyes at the suddenness of his words, then she became deliriously happy all of sudden.

She smiled a big smile as small tears began to form, "I love you too."

She kissed him again, and she felt her chest explode with everything she ever hoped for, her heart and emotions going off like fireworks.

Genos could hear their words to each other, he nearly cried himself. What did he do to derserve watching and hearing all this?

The answer certainly wasn't an easy one.
