Constant Variable (Senku x Reader)

7: Where Two Million Years Have Gone

Said person rolled his eyes at the blonde's retreating back before turning his attention. "Thanks for helping me back there, (Name)."

"You're welcome, Senku."

With that, the two of you joined Kohaku. When you saw how she was carrying the jar once more, you remembered the incident from earlier on and worried that something like that might happen again, you rushed over to help her.

"Here, let me help you." You supported the jar and together, both of you placed the jar onto the ground, careful not to spill a single drop of water.

A grateful smile graced Kohaku's lips as she said, "Thank you, (Name). Unlike a certain somebody, at least you're of actual help."

Rubbing the back of your neck, you smiled sheepishly. "It's no big deal."

"Well, let's get going then," Kohaku commented, back to her usual serious self. "We still have quite a long way to get back to my home."

As the blonde moved to lift and carried the jar, you instantly tried to stop her. "You shouldn't exert yourself too much, Kohaku. After all, you're still recovering."

"(Name) does have a point," Senku spoke up in a disinterested voice. "It'll be a waste of time again if we have to make another trip back here."

Blue eyes were twitching as Kohaku whirled around to face the scientist, growling, "Whose fault do you think it was?! Trying to play the hero when you knew you couldn't handle it! Even (Name) here has more common sense than you!"

Senku opened his mouth, ready to retaliate but you quickly jumped in, wanting to avoid another argument from breaking out between these two. "I'm sure you already have a solution in mind, don't you, Senku?"

One side of his lips curled into a confident smirk as red eyes twinkled. "Of course, what do you take me for?"

Lifting a brow out of curiosity, Kohaku asked, "And what exactly do you have in mind?"

Senku's grin widened as he let out evil cackles, rubbing his hands together in excitement. "Oh, it's going to be something fun and exhilarating."

Meanwhile, you were filled with a sense of unease at whatever Senku had thought of.

"I really have a bad feeling about this," You mumbled worryingly, but the other two didn't hear you as Senku led the way towards the clearing where Kohaku was rescued previously.

Time skipped

Eek!" You let out a fearful shriek and clung tightly onto the automobile that the three of you were currently on as it zoomed down the slope; (h/l), (h/c) hair whipping behind you.

Meanwhile, Kohaku's lips were curled into an excited grin with both arms thrown wide open, enjoying the feeling of wind rushing through her hair. "I'm impressed you built such a useful thing so quickly!"

"It wasn't quick," Senku replied from the back of the vehicle. "I managed to use the pulleys from yesterday as wheels. Civilization births civilization. Applying developments is the basis of science."

The younger female stared at the scientist in awe from over her shoulder before turning her attention back to the front when they came to a fork in the road. "Turn right up there."

Senku did as told, except he steered the vehicle into the opposite direction of where it was supposed to go and ended up crashing into a tree. The three of you were sent flying as the automobile was smashed into pieces on impact.

Thanks to her quick reflexes, Kohaku managed to land safely on both feet with the jar held securely in her grasp, preventing another spill from happening. Senku weren't as fortunate as his face planted into the hard ground while you landed on his poor back which broke your fall slightly.
