My Own Science (Dr Stone Senku x reader)

Learning something new

You guys created a vacuum tube to seal the medusa away, that way no one can activate it, as a safety precaution. This decision made Ryusui figure the secret of the device, that it can revive people from the dead as well.
"The instinct of a captain really is something!" you said, impressed.
"And don't you forget it!" he proudly snapped his fingers.
As far as your globetrotting mission is concerned, you needed to found one final city, in Indonesia, aka. Rubber City. They were a abondance of those rubber tree, the sap of which was the primary ingredient to make rubber. Got some rubber, revived people, built houses, city founded! This was way quicker than you expected. Now it's back to Japan! On the way there, Chrome and Suika came to you.

"Help us make a rocket!!!"
"Guys," you sighed. "I'm already busy with my own stuff, I can't."
"(Y/n) please!" Chrome leaned closer. "We're going to need your modern world knowledge! To help us create a return vessel in secret!"
"I can't help you, I'm sorry." you turned away. "Plus, don't you remember, Senku said we don't have time to make one."
He clenched his fist.
"Don't you want him and the others to come back?! This is the only way!" you pursued your lips. "If they don't wanna make themselves a way to return home, we gotta craft it ourselves! We're gonna need your input, you're from the modern world! You know more about rockets than we do, that's for sur-"
"I am not a rocket scientist Chrome!" you suddenly looked at him. "I'm a musician! There's nothing I can do! I'm not-!" you cut yourself off and turned away again when your voice cracked.
"(Y/n)-chan..." Suika said with a concerned look.

There was a moment of silence. Chrome has known you for long enough to be able to tell that it hurt you to say this. Out of everyone here, you were probably one of the people who suffered the most from this turn of events.
"...Alright." he finally said. "Then we'll do it ourselves!"
You huffed a smile and looked at him.
"You two, alone? You can barely do three digits multiplication, and Suika's a kid."
"Th-that doesn't mean anything!" she shook her head. "I'm still a scientist!"
"Exactly!" Chrome said. "We're people of science, whenever a thing seems impossible, we do it anyway!" he tapped his own chest with his fist. "That's how science works, we try again and again! This time, we just gotta work crazy bad and fast. We all gotta be there for the final victory toast! That's the true way to win! That's our happy ending!"
Your eyes widen slightly. His words hit you more than you thought they would, like you were reminded of the Kingdom of Science's whole philosophy. You looked down.
"Even if I wanted to, I still can't help you." you looked back at them. "But I know someone who can."

You told them to follow you, which they did, confused. The three of you went to Sai's workplace.
"Hey, remember when you told me about how, back in India, you'd teach math part-time to pay the bills?"
"Uh, ye-?"
"Well I hope your teaching skills are still sharp, 'cause these two need to learn math." you pointed at Chrome and Suika with your thumb. "Up to rocket science level, at least."
"What?!"
He was even more shocked when you guys explained your secret project.
"But, starting from square one..." his expression turned more serious. "It won't be easy."
"They're quick learners, trust me." you smiled. "Nothing they can't handle."

He looked at them.
"Are you two serious about this?"
"Damn right we are!!!" they said at the same time, mimicking your way of speaking whenever you'd be really hyped. "Mad serious!!!"
You couldn't help but laugh. Say smiled at their enthusiasm.
"Then get yourselves a desk." he rotated his black board to write on the other side. "We're starting right away!"
Chrome and Suika cheered with you.
"Now we got our own crafting project!" Chrome said. "Everyone is gonna be there to celebrate our victory against why-man, thanks to our round-trip rocket!"
You smiled, but to be completely honest, you were still skeptical.
'How will they alone be able to do what Senku and Xeno said was impossible...?'

Once you guys reached land again, you put agriculture back on track by setting up rice fields, which allowed François to make a bunch of new food. You cried when eating onigiris for the first time in 3,700 years, along with Ukyo.
"I'm...overcome." he said as you both softly sobbed. "I'm not even sure why. It's not like I constantly snacked on onigiris in the 21th century."
You sniffed and leaned back.
"It's called Proust's madeleine." you said, your voice wavering a little bit. "It's a taste, smell or sound that unlocks long-lost memories." you covered your eyes and leaned on him. "I'm having a flashback!"
He chuckled.
"Madeleine?" he asked.
"Yeah." you sniffed again, the two of you feeling better with this change of subject. "Marcel Proust, French philosopher. One day he was having tea with his mom and she got him a madeleine. He dipped it in his tea and ate it, and he also had a flashback of when he was a little kid and he ate that same thing. And he got all emotional because he forgot about that part of his childhood, like we are right now!"
