My Own Science (Dr Stone Senku x reader)

There they go

While you happily hopped towards the balloon, Gen presented the cards to Ryusui. He noticed one of them were slightly more forwards and smiled.
"I see. If you really wanted my help, you should have just been honest and said so!" he picked it up. "But since you have Gen trying to pull these dirty little tricks, I'll charge you one million dragos for my piloting fee! Hahaha! The winning joker is mi-!" he stopped talking and his expression fell when he looked at his card and saw that it was the three of heart.

"Oof." you giggled at his expression.
"Big oof." Senku added, smiling.

"Oh! What's this?!" Gen showed the card he 'picked'. "*I* pulled the joker?! No way~! What a shock!" he waved it in front of Ryusui's face. "I didn't want this! Whatever will I do~?!"
You and Senku smiled, understanding his plan. You glanced at each-other before walking up to him.
"What, you don't want that?!" Senku pointed at the joker, making an adorable face. "That's like, a super platinium rare ticket! You might never get something like that again! This is humanity's first flying device of the new world!"
"Plus it'll be just the three of us!" you added. "An epic adventure with just us the boys~!"
"Yeah~ you're right." Gen leaned back. "But I'm sooooo scared of hot air ballooooons!"
"Oh no~." you placed your hands on top of your head. "What a predicament~."
You snickered and turned around, Senku took a step aside so you were behind him, hiding you from Ryusui. Who seemed to have taken the bait.

"H-Haha! In that case," he snapped his fingers. "I don't mind trading with you!"
You had to hold back another chuckle when you saw Gen smirking right before wearing an innocent expression and turning towards him.
"Really~? But~ I mean, I did get so lucky and pull this ticket after all. So~ I couldn't exactly give it away for free..."
And Ryusui did not hesitate to dump a mass amount of cash in front of him. Gen cackled at his money while he was happy with his joker. A total win-win situation. Now buying the oil from him won't be a problem for sure!

"Awesome, so we're all set right?" you asked Senku.
"Sure. We'll check the weather and prepare the balloon. It'll take some time but we'll get off the ground in time for sunrise."
You smiled and excitedly shook your fists.
"Oh my god it'll be so beautiful! I can't wai-!"
"I'M RARING TO GO!!!"

You yelped in surprise. You all looked over to see Chrome walking towards you with the upmost determination. He looked like he could pass out at any second.
"Chrome?!" Kinrou exclaimed. "Did you run all the way back?!"
"What?! All the way from the village?!" Ginrou said.
He stopped in front of you and extended a hand.

"Give me your joker (Y/n)!"
"No fuck off!" you turned a bit as to protect your card.
"Oh come on! I've never flew ever in my life!"
"Well I haven't either! I also really want to get on that balloon!"
He took some panting breathes and hung his head down.

"With these eyes of mine," he said. "I want to see from up the sky what the world is really like... You yourself told me that the earth is round." your expression softened. "But we've lived all our lives in this little village...so all we do is hear." he paused. "All we'll ever be able to do is hear about things from you guys. So that's why..."
He took a moment to catch his breath again. He noticed something and looked up. You were handing him the joker.
"Here." you smiled. "Sorry I got so defensive."
"You always get defensive (Y/n)-chan." Gen smiled. "Are you sure though?"
"I'm sure I'll get another chance someday."
Chrome took a moment to appreciate your bro-move and took the card.
"AAAAALL RIIIIIIGHT!" he raised it in the air in victory. "Thank you (Y/n)!!!"
"You're welcome Chief." you smiled.

It was still dark when the hot air balloon was ready to go. Senku let a little balloon fly in the air so he could calculate the direction of the wind and its speed, and Ryusui deducted that the weather was in the perfect condition for flying.
Everything was quiet as the balloon started to float. As soon as the ropes were cut you let out an 'Ow shit!' and ran away. Everyone was quite confused but they quickly understood when you quickly came back with your trumpet. Senku chuckled.
