My Own Science (Dr Stone Senku x reader)

Don't, stop it. Stop them! The feels are unstopable!

He smiled back before looking at the refrigerator.
"Cold sleep... I haven't even heard of it outside of spaceships from sci-fi movies."
Now you were going to say something like 'lol ur gonna be a sci-fi-boy!' probably followed by asking him about his favorite sci-fi movie, to start a conversation. But to your surprise, and the further cracking of your heart, Senku was the one who spoke up.
"Spaceships huh? The Soyuz had three people on board. If you had to choose from the people around now, who would you take with you to space?"
"Let's see..." Tsukasa paused and looked at him. "What is this? You want me to list the most capable among our people?"

"Huh? What are you saying? I was just asking."
"Now...here...at the very end... Why would you ask something so pointless?"
He was silent for a moment, whis back turned on you both, you couldn't see his expression.
"Is it not okay for us to have a pointless conversation?" he asked, which only crushed your heart even more.
Eventually, Tsukasa smiled.

"Let's see...Taiju and, um... Senku, you have a great inquiring mind for the stars, but you're unreliable as far as strength and stamina go. So I think it'd be Chrome."
"Yeah, I don't think I'd bring me along either." he smiled while you nodded. "There was that girl with the shells in her hair right? Who was that?"
"She's a reporter... She's my valuable source of information for deciding who to revive."
"Kukuku, and here I thought it was your kink. The world strongest primate has a thing for Marilyn Monroe looking girls."
You puffed a chuckle.

The conversation the three of you had was so friendly, you forgot about your sadness for a brief moment.
"And then I said: thoughts before thots!"
You and Senku laughed, Tsukasa tried not to so that it won't worsen his lung.

Though, everytime Tsukasa talked, his weak voice just hit you, but you did your best to not show your sadness.
"Again, sorry I lied to you." you said.
"It's okay...I would've done it too."
"And by the way, now that we're being honest with each-other, I gotta tell you: I said I was okay with you killing people, obviously I'm not."
"I understand..."
"I mean I get it, I get where you're coming from. But killing all adults is just too...too much. Plus, Tsukasa..." you leaned closer. "What about Jonathan?" you wheezed.
Tsukasa held his breath, trying his best not to laugh.
"(Y/n)...don't make me laugh, please." he managed to say.

"Sorry sorry." you smiled. "Dude, could you imagine if we bring Jonathan Frakes back?!"
"I know exactly what we'll do... We'll give him his own cave...
"Tsukasa." you said, knowing where he was going with this.
"People will come to him for answers."
"Dude." you tried not to laugh again.
"And he'll always respond by facts or fiction." he smiled, enjoying this.
"Stop." you held your stomach.
"And at random point...he'll hit you with a 'we got ya'."
You laughed out loud, hitting the floor. Meanwhile, Senku looked at you. He didn't understand that inside joke.

"So...(Y/n)." Tsukasa said. "That trumpet...the day I found you... You were the one playing it."
"Yep."
"Then, that twin sister was also you." he paused. "Heh, such a simple excuse."
"I mean..." you scratched your head. "I pretty much made her up."
"I don't believe so..." he looked at you. "You're great at music, you're strong, and you have a real presence... I always notice whether you're here or not."
Your heart skipped a beat.

"Could you come closer? I...want to ask you something."
"Uh, yeah."
You leaned closer to his face so he could whisper in your ear.
"If you...had encountered me first... Would you have fallen for me instead?"

Your eyes widen, you opened your mouth but no coherent words were said. You glanced back at Senku, who couldn't hear anything and had his back turned on you, still working on the refrigerator. You looked back at him.
"Tsukasa, I-"
"Nevermind... I'm sorry for asking something like this." he smiled. "I wouldn't know what to do or say if I knew the answer anyway."
His smile was so sad, you felt your chest tightened. You put a hand on his cheek and pecked his other one. He gently gasped, and you smiled at each-other.

"I heard you made a guitar." he changed the subject. "I'd...like to hear you play."
"Ah! Yes, of course!" you stood up. "I'll go grab it, don't do anything until I'm back! It'll just take a second!" then, you ran out.

Now alone with Senku. A moment of silence passed, when none of them said anything.
"Senku..." Tsukasa eventually said. "During those six months of us living together... whenever you'd be working on something...You'd hum a tune."
"Really? Don't remember."
"Yes...And now you stopped doing that..." he paused. "It's because she's here now...isn't it?"

Senku didn't respond. He paused for a brief moment before continuing his work. But Tsukasa knew the answer. He remember when he asked him where he heard that melody, Senku just shrugged. But that same melody, he heard it from you too.
"I dunno." he eventually said. "It's just a catchy tune."
Tsukasa smiled.

"Okay I'm back!" you ran back, your cheeks slightly red from running.
"Calm down, take a breath." Senku said, seeing you panting furiously.
You took a moment to catch your breath, then you sat down beside Tsukasa, preparing yourself to play.

"Will this be the first time you play it?"
"The second actually." you smiled. "Sorry, you won't have this honor."
"Oww." he chuckled.

"Anything you have in mind?" you asked.
"Something you composed. I want to...hear what comes from your heart."
"Alright then."
You thought for a moment, then you began to play. It was soft and soothing, and you tapped the cave's ground with your feet to have a little beat. Tsukasa closed his eyes to better appreciate the music. You finished on a classic crescendo.

"What do you think?"

Silence.
You heart sunk.

"...Tsukasa?" you kept smiling. "Did you like it?"

Silence again.

"Tsukasa..."

Senku quietly looked down, his fists clenched.
Your expression fell. After placing your guitar aside and took Tsukasa's hand in yours. You bent over, your shoulders and breath shaking. You eyes were closed, so that no tears could fall, Tsukasa told you he hated seeing you sad, so you wanted to stay strong for him. You sniffed.

A long moment of silence passed. You let go of his hand and backed away. Taking a deep breath, you opened your eyes. They were slightly red and puffy, but no tears.

"Do you want a moment alone with him?" Senku asked.
You looked at him.
"I was about to ask you the same thing." you huffed a chuckle.

He walked up to Tsukasa, kneeling down beside you.
"We'll turn him into stone. We'll find out how to petrify him, and bring him back. We'll save him."
You didn't know if he said it to comfort you, or himself.
"...As always." you smiled.
