Constant Variable (Senku x Reader)

1: Stone World

'W-What's going on?! A-Am I dead?!'

Your mind was in a panic mess, unable to think straight as darkness filled your vision. You could feel the fear thrumming through your veins, rendering you motionless as it took over your whole being.

You had never been afraid of the dark, not even when growing up as a kid. You believed, just like light, the inky blackness had its own beauty to it. Besides, it was never pitch dark as there would always be remnants of light if you looked hard enough.

When night fell, there would be the moon that bathed the earth in its silvery glow as millions of stars blanketed across the vast space. Likewise with the sun when it rose high in the sky, there would be pockets of shadows dancing here and there.

So, there was never a reason for you to be frightened by the darkness. However, the darkness that currently plunged all mankind was of total blackness, not a trace of light to be seen.

'I-I have to get out of this darkness!'

In desperation, you tried moving your body but you realized it couldn't move at all. Not one to give up, you wiggled your fingers and toes, shaking your head or even something as simple as blinking but it was fruitless.

'Is that it? Is this how I'm going to die? At a young age of 16 and turned to stone? I didn't even get to say goodbye to my loved ones.'

As your mind drowned in despair, you could feel your consciousness giving up and slowly began to ebb away, surrendering to this eternal darkness you were plagued with. Unshed tears welled up at the back of your eyes at such a sad way to go, your heart churning with regret for the one thing you didn't get to do.

'As I wither away with time, the only one thing I regret will be not telling Senku my feelings for him which I should've done so when I still had the chance. I guess the saying "You never know how precious something is until you've lost it" is true after all.'

You scoffed at the irony of it. As your conscious came to a standstill, your eyes fluttered shut and the last you remembered feeling was the overwhelming sadness washing over your heart as it beat for the last time.

'I'm sorry and I love you. Goodbye, Senku.'

...

(Name)!!

Your eyes flew wide open as you let out a huge gasp, your lungs inhaling large gulps of air as your heart went into overdrive in pumping blood constantly throughout your body.

The memory of Senku reaching out to you in desperation as he called out your name that echoed faintly in your ear flashed through your mind. You remembered the slight fear you saw in his eyes, afraid of losing you as his fingers barely brushed against yours like a flutter of butterfly wings.

At that moment, you felt like slapping yourself. How could you give up so easily when in that very last instant before darkness enveloped you, the only thing on Senku's mind was to reach for you so he could protect you from whatever harm the green light would befall upon you?

It wouldn't be fair to the scientist that even in the last few seconds of his life, it wasn't about him but you. For someone who was all about facts and figures, his action really showed that he cared more than he let on.

And you weren't going to let Senku's emotions go to waste just like that. In fact, you were going to prove him wrong that emotions weren't illogical and mattered as much as science did.

But first, you had to break out of this darkness and knowing your green-haired friend, he was already thinking and figuring how to get out whatever prison he was being encased in.
