My Own Science (Dr Stone Senku x reader)

One step closer

Still, when the news was announced, you celebrated with everyone.
"Yeah! We're coming for ya Why-man!" Taiju threw his fists in the air.
"We're gonna kick your ass!" you added.
"Now we can take the fight to him before he strikes!" Kohaku exclaimed. "We'll hit him hard and fast!"
"Via our one-way rocket, which ends with some of us petrified." Senku smiled.
"...Cool thanks for reminding us!" you laughed, it was very bittersweet.
"Have you decided on a song yet? It will be the last one I hear from you in a while."
You took a deep breath.
"I made a list of possible choices. Celine Dion's 'It's All Coming Back to Me Now' is a bit...very much cheesy, but I like it."
He snickered.
"Very cheesy, and a bit cringe too."

"This will be the last time you hear me, anything will be cheesy and cringe at this point." you faced him. "Think of the song like a promise. Anytime I'll think of you, even years, decades later, all my feelings for you will come back to me. That'll never change." you smiled, your eyes teary. "I'll sing that song with all my heart, and by the time I get to the outro, I will cry."
He smiled, but it also seemed bittersweet.
"I'll make you so leave you a bunch of messages, like video blogs or...voice messages." you paused, just now making the connection. "Like your dad did."
Senku pursued his lips, his eyebrows furrowed. He already noticed the parallel, but being reminded of it... For a brief moment, he looked hurt, sad, about to cry even, it made you want to hold him and never let go. But, like always, he eventually regained composure, but his eyes remained glassy.
"At least this time, I get to say goodbye." he smiled. "Right?"
There was a slight crack in his voice that you could only notice if you've been around him long enough. You kissed him and pressed your forehead on his, your eyes closed so as to not cry.
"Not yet..." you whispered. "You're not gone yet."
His expression softened. He held your hands.

You went to Suika and Chrome to tell them the news. When you walked in, you saw Suika first.
"Suika, they-"
"We heard." she hugged you, sobbing. "I guess it's a good thing... But now, they're all so eager to launch the one-way rocket.We couldn't made the deadline to build our round-trip rocket in time."
You bit your lower lip as you gently patted her head, holding back your own tears and holding her tightly.
"How is Chrome handling it?
She pointed to the back of the room. Chrome was still working full speed with an intense focus, but you could see the panic in his eyes, and the sweat soaking his face. Your eyes widen when you saw him.
'He's still working.' you thought, baffled. 'Even after hearing that he failed...'
You nothing that his hand, the one that wasn't writing, was clenched into a shaky fist. It pained you to see him like this. But it was also inspiring in a way. Gently, you pushed Suika away and sat in front of him. You took a bunch of blueprints and began to study them in details. Chrome looked at you surprised, he was about to say something when he saw the grave look on your face, he smiled and went back to work.

'If he was ready to trust me with this, then there must be *something* I can contribute!' you thought. 'Come on (Y/n)! Remember Senku's science babbles and compare them to this! Any difference at all! Big or small!'
"Ah."
"What?" Chrome immediately looked up. "What is it?!"
"The spaceship we're making, it's a one-time launch." you showed him the blueprint. "In the 21th century, they were sent big piece by big piece." you turned it back to you. "But it makes sense here, since we don't have enough to-"
He snatched the paper out of your hands and looked at it closely. His face lit up and a big smile formed on his face.
"Finally!" he exclaimed. "My flash of inspiration! A way for everyone to survive and make it home! In a two-way rocket made possible by science!"
He then went back to work, even more focused now. You and Suika tried to ask him what his idea was, but he wouldn't answer. At some point, you went back home. You haven't heard from Chrome in a few days, then he went to you and asked, without even saying hello:
"We need to organize an event! To present our plan and make them understand!"
"I'm all about that, let's do this." you gave him a thumb up.
