Senku Ishigami One shots

Such A Tease

(Time set in modern universe.)

Being a childhood friend of Senku as if both of you were attached in the hip from birth. You were soon to be part of his free labor when he found out the wonders of science brings.

It didn't really help that both were you are just a door a way from each other. Both parents seems to be amused on the children's interactions. One purely amuse and amaze eager to learn from the boy. As the said boy enjoys the wonder and awe on the girls eyes. Promising to himself to make more experiments for him and his companion to enjoy.

That is until they reach teenage years.

Once both of them reached teenage years. (Y/n) seems to develop an annoying habit for Senku.

She seems to like teasing the hell out of him in any given chance. When asked about the matter her only reply was.

"I want to see what you would look like flustered."

"Good luck with then, stupid. That's 10 billion percent not gonna happen."

"You're not sure~"

Grumbling Senku brought up his hand to his forehead already feeling the upcoming headache. Hormonal unbalance can be pain in the ass. Deciding to ignore her and focus to his current project soon becomes hard to focus as he felt your stares bore into his skull which Senku released a frustrated sigh at.

"What is it?" Senku asked not looking up from his work.

"Hmm?" (Y/n) replied tilting her head to the side even tho she's aware he can't see her.

"You're staring." Senku stated.

"And? Does it make you uncomfortable?" You asked leaning close eyes drifting from his work to his handsome face.

"Yes. Just spit out whatever's on your little mind already if that'll make you stop staring at me." Senku said as he turned around to look for a screw.

"Y'know you're aging quite well. Despise the voice cracks now and then which would gave me a good laugh. You're looking quite attractive as hell." (Y/n) said as she leaned back to take a good look at Senku. Before humming to herself.

"Sure your gravity defying hair looks different or well, looks like a leek. Your intelligence and handsome face makes you attractive." You stated before leaning close as if observing your own project.

"It's just your hormones acting up. Are you done?" Senku sighed as he looks around his project to check no screws were loose.

"Hmm, I think so. But I really do mean what I said Ishi-chan. I might be developing a crush on you." (Y/n) smirked poking Senku's cheeks. Causing the male to grumble in demise.

"Please don't. Get out or I'll test this new project on you to see if it works." Senku said as he slapped your hand away from his face looking at you soon after to give you a glare.

"Heh, I'll take my chances after all, Taiju is busy helping out Yuzuhira. I'll be your only available guinea pig." You replied before laying down on his bed.

"Hey! Don't get your germs all over my bed!" Senku exclaimed as he cleaned up his work place hearing an offended gasp from you.

"Ah! The audacity. You're the one who hasn't showered yet. If there's someone between us reeking germs it's you." You scoffed standing up going to his closet to grab his clothes and towel. Shoving it to him causing him to grunt at the impact.

"Go take one, would you? I'll take over the cleaning." (Y/n) said as she basically kicking Senku out of his own room.

'Seriously, that girl.' Senku grumbled to himself.

As he was in the shower, thoughts clouded his genius brain. From recalling previous projects, the failed ones and the successful, to upcoming inventions he look forward to create. As suddenly you popped up in the middle of his thinking causing him to be confused.

Why the hell were you there?

Sure, you've always been by his side when he started experimenting. It was a given he would suddenly thought of you right?

Senku sighed grumbling at himself in the shower rinsing off the soap on his body and shampoo from his now down hair.

'Stupid hormones.'

He remembers your first time flirting with him out of the blue.

"You like stars and space right, Ishi-chan?"

"Yes, what about it?"

"I wish I was a star then."

"For what reason exactly?"

"For you to like me."

He remembers it clear as day. The look of grimaced on his face the moment you said those words. As you in the other half laughed at his expression saying that's not the reaction you were expecting but it came no surprise from you. Since well, you grew up with him after all.

Deciding it was time to finish up. He got out of the shower drying up his body and hair (as it slowly goes back to defy gravity). Dressing up with his clothes provided by you. He goes back to his room perfectly cleaned with you sleeping on his bed.

Taking this as advantage to observe you. He crouched down in front of your sleeping face as he took in your peaceful expression. As he questions himself.

'Do I find your physical appearance attractive to me as well?'

Staring intently to the details along your face he found himself slowly smiling when you grumbled something in your sleep.

'It seems I sadly do huh.' Senku sighed to himself.

"Have a good rest then, silly girl." Senku said as he leaned down to give your forehead a kiss. Standing up to have some rest on his own on the couch.

"Who knew you have it in you genius?" A voice from his back stopped his tracks as he quickly turned around to see your smirking face at him.

For the first time. You finally saw him flustered.

"There! That's the expression I was aiming for!" (Y/n) exclaimed hastily getting up to pry away Senku's arm from his face.

"You were plotting this!" Senku exclaimed turning away his face as both of his arms were locked away by the girl in front of him. Curse his weak self for only focusing on science and not exercising.

"C'mon! Let me see!" You exclaimed pushing him into his bed successfully caging him by using your weight on top of him.

This doesn't bother Senku at all growing up with someone like you, physical contact with you isn't something for him to get troubled by.

As few moments pass the blush on Senku's face slowly died down as he wondered why did you suddenly got quiet. Slowly he peeks at you from the corner of his eyes only to find you covering your face with one hand.

Seeing this Senku frowned before turning his head to face you now before leaning up to you. Wondering if he should apologize or not.

As he was close enough to be face to face with you. Your hand suddenly left your face as you quickly give him a kiss on his forehead also.

Senku processing what just happened as his face slowly reverted back to being flustered.

"There. I see it now." He heard you whisper as he looked back to see your (e/c) eyes gleaming with mischievous with a matching smile of cheekiness.

Senku groaned in defeat before laying down on his bed with you setting yourself beside him.

"Troublesome." Senku muttered as he put his arm on his face.

'You're really such a tease.'
