The S.I.M.P Gene

Pairing: Saiki Kusuo x Reader

Warning(s): Actually inheriting a dominant trait from his father righsldnsocsesssghhh~

A/N: Rewatching Saiki Kusuo with my sister and I don’t care about the risks, Kusuke is my husband. But this ain’t bout him.

Summary: Saiki is leagues away from resembling his father in any way, shape or form...Except...

——-

What a pain.

Of all the things to inherit from his father, why this? And why now?

He was having a hard enough time dealing with his classmates, you mean to tell me he had to worry about you, too?

No that he has any issue with you.

On the contrary, you were wonderful. Amazing, in fact.

He likes you.

And therein lies the problem.

Kusuo is very level-headed and he trusts his common sense.

Even though the world around him is… well… Not as level-headed and well-versed in the ways of common sense. 😅

So the realization that he is capable of having this… this unrestrained affection for you blindsided him.

Why is he doing your homework for you today when he is a firm believer in people taking responsibility for their own mistakes?! Oh well, it’s just this once.

He has no choice but to listen to other people’s problems, but why is he actively trying to help you with yours even though it’s going to be more trouble then he’s willing to deal with?! Oh well, it’s just this once. (It’s not)

Sigh. He can’t deny it. He likes you a little too much.

He likes how you aren’t afraid to say what’s on your mind, but at the same time you speak sense.

He likes that you have a good head on your shoulders. Every now and again you can’t help yourself with the Saiki gang, but the fact he can sometimes avoid being dragged into his classmates’ messes just by leaving with you whenever you don’t have time for it is quite refreshing.

He could actually trust you with knowing about his powers because you had a little secret of your own!

No, you weren’t a psychic too.

You had your own powers to keep under wraps.

He likes your laugh, unrestrained and full of feeling. It gets really embarrassing when you do it in public but when it’s just you and him, it’s fine if you let it rip!

——-

Can we talk about how he enjoys being seen with you by Teruhashi way more than he should?

Trying to ask him out in front of you as to intimidate and overshadow you, but at the same time she can’t let it look like a date because of appearances~

Kusuo is just done, and he’s not cool with Teruhashi snuffing you like that.

But you don’t even flinch. You were scared of no-one, and you better believe Saiki filled you in on what she was really like so you knew just how to deal with her.

“Hi Teruhashi, L/n here!” You wave your arm in a wide arc in front of Saiki, making your presence known.

“Given how nice you usually are, I’m sure you didn’t mean to pretend like I wasn’t here-“

‘She definitely did.’

‘Oh, I know.’

You slide over to Saiki, arms touching at the elbows. “-but Saiki’s taking me out this weekend…”

“Oh, r-really? If you don’t mind me asking, where are you going?”

At this, you waved her off. This girl really had it bad for Kusuo. Well, too bad, your plans come first. “It’s a secret~”

It drove PK’s perfect pretty girl nuts!

‘Seriously?! That girl’s been here a whole three months, there’s no way she hasn’t done some exploring on her own! She must be using her ‘new girl’ status to get close to Saiki! Saikiiiiii!!! You CAN’T think she’s prettier and more perfect than me, you just CAN’T!’

Kusuo didn’t know if he could say you were perfect, but he could say without hesitation he preferred looking at you over her. Also, considering that he liked you… a lot…

And he didn’t like Teruhashi… at all…

The comparison just couldn’t be made. Not without making a permanent enemy out of every man in the universe.

He was relieved that he didn’t have to go on another date with Teruhashi. He knew you were only baiting her because she had been rude, but he couldn’t ignore the pleasant humming his heart was doing when you revealed that you were also defending your plans together because you really wanted to spend time with him.

“Sorry, I may have made it seem like more than it was…”

‘No complaints here. I’d rather not go anywhere with her.’

——-

While he was alone one day, investigating these… *gulp* feelings… he ended up getting an unexpected unwanted phone call from his older brother.

At first, he was just gonna let the phone ring. He had more important things to worry about and his super villain brother was not one of them.

But Kusuo knew Kusuke wasn’t going to be snuffed that easily. He’d call the house phone next and his mother would make him talk to him or worse, he would show up in person.

He was better off taking this call and getting on with life.

And baybee! Somehow. Someway.

Kusuke called asking about you. 💀

Like, how sway? Kusuo didn’t say a thing about you, made certain not to alert his parents of your existence but he still found out!

“Silly, did you forget that I see everything? You’re slipping~”

Oh right. His brother spies on him whenever the mood strikes him.

Ugh. Pain.

Having his brother in his business was thee last thing he needed right now. But he may as well get a second opinion. So he spills a teensy bit of tea.

He admits his strong attraction to you, despite the two of you being just friends, and it’s not even in the way most high school boys are attracted to girls.

He suspects that, despite his better judgment, he might be letting you have your way a little too often, even when it doesn’t benefit him in the least to indulge you. To be fair, the amount wouldn’t look like much from a normal person’s perspective.

It’s just a huh-yuuuuge leap for Kusuo personally.

He doesn’t even pursue relationships, but you don’t push him to be one way or the other and it makes him want to reconsider.

And Kusuke, classic evil Kusuke, had to pipe up and say the worst thing ever.

“The answer is very simple, little bro. You’ve inherited dad’s simp gene, and the trait is surfacing for this L/n girl.”

……..The AUDACITY!

Kusuo hung up right in Kusuke’s face. He should have known better than to expect anything helpful from him. Not about this…

A simp, huh?

Laughable.

The idea was as impossible as it was ridiculous. Saiki Kusuo was many things. A simp he was not. He knew better than that.

And yet… The more he thought about it, the more similarities he found between the way his father talked about his mother and the way he felt about you.

He was not a simp, but every day spent with you, he felt as if he were slowly creeping towards something scarily close….

Ugh. NO!!!!

While most boys wanted to be just like their fathers, the thought that Kusuo actually might have inherited something, anything from his father, wasn’t a pleasant one.

And this was the worst possible trait he could have gotten. Well. Aside from the freaky skill of polishing $300 leather with one’s tongue but we’re not getting into that.

For a week straight Kusuo gave his father the cold shoulder. Every attempt at any father-son bonding was rebuffed and he refused to help him with his powers.

“I don’t get it Kusuo, why are you being like this! You’re even more surly and cold-hearted than usual!”

‘You cursed me with your incurable disease. I’ll never forgive you.’

“What are you talking about?!”

It took his mother, his grandmother, his friend group AND you to patch the bridge between the two of them.

Oh well, he’ll figure out how to deal with his feelings.

He’s Saiki Kusuo. Making the most messes was his unfortunate specialty.
