"Damnit Baldy, pay attention to me! I know you're in there being lazy!"

Saitama sighed as he continued flipping channels on his futon, ignoring Tatsumaki's screams. Genos, staring at the door as her knocks grew louder, got up from his spot at the table tapped his mentor on the shoulder.

"Master, should you not get the door? Tatsumaki may just bust it down if you take too long."

"Ah, so troublesome..."

Slowly getting up and stretching, Saitama opened the door and looked down, inwardly grimacing that it was indeed the small, pouting form of Tatsumaki at his door.

"Finally, making me wait that long! Fight me, Baldy! Bean sprout! A-class-"

Saitama tapped her on the head and stared, expression deadpan as ever.

"Nah."

Slamming the door, Saitama spun around his heels determined to find the perfect show to waste a day on when he heard frantic knocking. Genos chuckled a little at her persistence, earning an annoyed look from his roommate and teacher.

"Hey you, quiet."

Clumsily trudging his way over to the door again, Saitama slowly opened it hoping that the green-haired esper had left. Preferably also leaving an apology gift.

...

Nope. She's still there, a little deflated but still there.

"Are you done throwing a temper tantrum, or...?"

"No! I-I mean, yes! Look, I don't need to explain myself anymore, I want a rematch!"

"But the weather outside is more fit to lounge in..."

Tatsumaki flicked him on the forehead, quietly hissing as she nursed her index finger for a brief second. She could insult that bald head all she wanted, but even she grudgingly admitted that it was tough as hell.

"N-No exceptions! We're doing this and we're doing this now! Ever since that first match, I've been training! It wasn't that much of a problem, but..."

Tatsumaki dramatically turned her head with a confident smirk, leaving Saitama still standing dumbly at his doorway. Did she want him to say something or...?

"Good girl."

Ruffling her green curly hair earned him a slap on the hand and a blush as the little esper scrambled away.

"Q-Quit it, geez! I-It's not like I was waiting for that, moron!"

What is this, some sort of anime?

"But you were so eager. Well, alright then, I guess I can make time in my busy schedule. Genos, I'm going to be out for a while, take care of yourself."

Genos, tilting his head towards the doorway, waved to Saitama.

"Yes, Master. I will make sure everything is as you left it when you return."

Nodding, Saitama walked out and closed the door, following Tatsumaki's retreating form. A random thought, however, stopped him in his tracks.

Oh wait, I didn't change into my hero outfit.

Oh. Well, as long as I don't get too much stuff on this hoodie...

It had been a few hours of constant running to keep up with Tatsumaki's flight speed, and Saitama mused that it was actually decent exercise. If he actually still needed to, this'd be a good route for a morning jog.

But on the other hand, there were so many good soaps on...

Absentmindedly drawing up a mental list of his favorite ones, Saitama continued to run into and through trees, boulders, and even a lake before he narrowed his final ten down.

"HEY! QUIT RUNNING! ARE YOU LISTENING TO ME, IDIOT?!"

Oh.

Screeching to a halt, Saitama flipped around and landed perfectly, creating a small shockwave.

"Right. So what is this battle anyway?"

Floating over towards him, Tatsumaki condescendingly smirked down towards him.

"It's simple even for a fool like you. Get over to me and tap me on the shoulder within five minutes."

Right as she said this, Saitama seemed to teleport right in front of Tatsumaki staring directly into her eyes, causing her to yelp and tumble backwards, flailing in suspension as she desperately tried to regain her composure.

"I-I-I still have to finish what I was saying, you brute!"

"Oh. Sorry."

The young esper sighed, straightening out her dress before casting emerald eyes towards her opponent, who seemed to be picking his nose. Resisting the urge to meld her palm with her face, she grit her teeth and continued.

"I will be attempting to stop you with a barrage of mental attacks. I won't bother trying to expend energy to throw rocks at you or whatever as I know it does nothing. Let's see you casually stroll over while your mind is being directly crushed, hmm?"

"Directly crushed, huh? Sounds painful, but ok. Do I win anything or...?"

"More like do I win anything. If I win, you must do whatever I say for one day like an obedient dog. If you manage to win, I...guess it applies to you too. B-But no lewd orders, alright?!"

Saitama tilted his head.

"Were you expecting one? That's kinda weird, Tatsumaki."

Face exploding into red, the flustered esper stuttered out an elegant reply of "SHUT UP, BALDY!". Taking deep breaths, Tatsumaki focused her mind onto Saitama's.

Meanwhile, Saitama was simply thinking about all the soaps Genos could be watching without him before he felt a small twinge in his brain. Figuring that it was Tatsumaki, Saitama began slowly walking towards her.

I never did go grocery shopping huh wait DAMNIT THERE WAS A SALE TODAY AUGHHHH NOT AGAIN no wait it goes on for like two more hours if I hurry up with Genos then maybe I can snag those buns on sale for-

Tatsumaki hissed as she tried to force all of Saitama's idle thoughts away and focus purely on limiting his motor functions. Pouring all her mental strength into trying to halt Saitama's movement and attempting to clog his mind up in return, Tatsumaki broke into a sweat and felt her entire body heating up from the exertion.

At least she was actually managing to slow him down, that had to be something, right?

"You're doing this on purpose, aren't you?! You disgusting worm, quit it!"

Tatsumaki sure is cute when she's trying hard huh

That did it.

Saitama let an amused grin show on his face as Tatsumaki gawked at him, face turning an almost imperceptible shade of red. Whether it was due to the fact that the thought stood poignantly out to her amidst the others or that Saitama was right in front of her face, she couldn't decide. Defenses thoroughly shattered, Saitama took two steps forward and took a hand out of his pocket.

Then he tapped her lightly on the shoulder.

"Let's have udon."

Staring dumbly at him, Tatsumaki opened her mouth to respond before collapsing, falling straight out of the air. Saitama, quickly thinking, flash-stepped over and caught her. The esper was light as a feather, and Saitama briefly entertained the thought of juggling her on one finger to make a few extra bucks.

"Working yourself too hard...ew, you're all sweaty. And you smell. I'm throwing you in the bath first chance I get, squirt."

"Shut up...stupid baldy Saitama...all your fault. Never pay attention to me..."

Saitama vaguely heard Tatsumaki as she latched onto his shirt, nuzzling her face into his chest. Shrugging at the action, Saitama began his trek back to his apartment. No dinner out is complete without Genos, after all.

A/N: So I heard that there was this new anime adaptation of this thing called One Punch Man. I watched that and loved all five episodes that were currently out. And then I dug deeper, and just concluded that everything involving One Punch Man was an indicator of a good time.

I wrote this on a whim, sorry if it seems like any of them are a little OOC. But hey, I'd like to hear your feedback. This'll probably be a two-shot, by the way, so reviews on the chapter or your thoughts on more OPM fics from me, either way I'm happy.
