Have Genosai.

Cuz it's too adorbz to not write about.

It was the first time Saitama has ever bothered to notice it.

"Sensei?"

"Aren't you overdoing it, Genos?"

The cyborg paused in the middle of washing the dishes, looking confused.

"I'm sorry sensei, but what do you mean?"

Saitama's brow twitched.

"Look at the plate."

"Yes…?"

"It's reflecting enough sunlight to burn the fucking wall."

True enough, Genos turns to the concrete beside him to find a small black spot staining the otherwise white wall. He gasps lightly in shock and hurriedly clanks the plate down before hurrying towards the wall.

"I'm sorry sensei! I'll fix this immediately." Genos says, reaching for his cleaning supplies that are surprisingly within reach.

"No. No. Please don't." Saitama replies, pinching his nose.

Honestly, the cyborg pushed himself too far sometimes.

The next time was a bit unnerving.

Genos seemed to stare at nothing, his grip still on the clothes he was folding.

It took Saitama 5 minutes to snap him out of it.

When he finally came too, Genos smiled.

But Saitama didn't like the way how it was strained.

The third time was annoying.

But he couldn't say he was all that annoyed.

Genos basically heated up too much and fainted.

And Saitama may or may not have been sitting outside of the professor's lab waiting for him because he can't make dinner because damnit he needs ingredients and it was Genos's turn to pay.

Fubuki stops by with Tornado and tells him he just doesn't want to eat alone. Saitama just scoffs.

He was annoyed to the point he was worried, after all. Fubuki's just overreacting.

Right? Right.

"We're going to adopt." Saitama blurts out all of a sudden as they eat lunch.

Genos tilts his head.

"I'm sorry sensei, please elaborate further-"

"I meant an animal. You know a dog or a cat." He continues, slurping some udon. "It might help with some stuff."

Genos frowned.

"Is my company not enough, sensei?"

"What? Nah. You're fine."

"Then why would sensei have the sudden urge to find a furry companion?"

"Actually, it's not for me, it's for you."

At this Genos pauses once again.

He stares at his master, only to get intimidated by a blank stare he usually had.

"What is the purpose of…?"

"You're too stressed."

They go to a shelter on their way back from the sale at the market.

Genos is slightly uncomfortable at all the puppies and kittens flocking his way while Saitama sits by the corner, idly chatting with the girl by the counter about breeds.

It takes a few minutes before a slightly flustered Genos approaches them with a ball of white fur, mewing avidly at them both.

It was a cat with a green eye. Only a green eye because it's other eye seems to be gone, seemingly gouged out.

The girl 'awed' when the cat went to lick at Genos's cheek.

They take the cat home, and Saitama sees improvements already.

Genos seems more willing to heed Saitama's advice of just 'chilling out and feed the goddamn cat it's been screaming for hours' which leads to less grumpy Genos and a more normal Genos (well, as normal as he could get.)

He also went to that specific spot in his table to write notes about his beloved master.

Which was good.

All good.

Saitama had taken up this weird habit of just watching Genos pamper the cat.

Genos rubbed the furball's ears, making it purr and lean toward his touch.

Saitama accidentally bites his tongue along with the candy he's been sucking on.

"FUCK!"

"Sensei?!"

The cyborg jolts up, causing the cat to hiss in alarm as well.

"N-Nothing. I'm fine."

"Are you sure sensei?" Genos tries to question further, but is stopped by a tug of Genosai's claw.

The cat meows in the most adorable way that Saitama can't blame it for the sting on his tongue.

Except he can. Because the cat did something.

"Huh? You're hungry? Ah, okay."

As Genos gets up to get some cat food, the baldy sits there, staring at their pet.

Since when did they decide on that name?

"Genos."

"Yes, sensei?"

"We will not name is Genosai."

"Why not, sensei?"

"Because, it sounds weird and it souns too fucking close to genocide."

"…"

"How about something simple?"

"Eggy."

"Genos-"

"I'm sorry, I don't mean to offend you sensei. But I just want to name him in your likeness."

"…Okay."

"Sensei?"

And so, the cat is now named…

…whatever they want to call it.

But hey, it gives Saitama the privilege to call it 'Schitt'.

Genos reminds him that he looks at the cat and treats him as some kind of second sensei.

Saitama immediately takes back the shitty nickname.

It's been a few weeks since the cat moved in.

Genos's mood had improved.

Saitama's didn't.

Because for some reason, he was jealous of a cat.

It's gotten to the point where he'd compete with the animal in the form of catching Genos's attention.

Damnit.

He had it bad.

"Sensei…"

Saitama looked up to see Genos with a frown on his face.

He blinked once.

The limp body (or pile of mushy meat, rather) fell on the concrete as the cat stepped up and mewled at Saitama, who glared lightly.

"I still get Sundays with him. And no interrupting conversations, okay?"

It meows one more time before following him back to the apartment.

Genos was back to being happy and chill, and Saitama was too.

But he still wasn't all that content.

After all, Saitama and the cat had a truce that lasted only for a while.

The next war will begin next month, and the hero was pretty sure he won't let a furball take Genos's attention that easily.

Maybe another one? A sequel with Genos's thoughts?

Review if you may.
