Constant Variable (Senku x Reader)

Epilogue: Constant Variable

"Yes, madam!" The brunette saluted, earning an eye roll from Kohaku before turning on her heels and making her way to join the other two who were already starting their warm-ups or more like Kinro was shouting at his younger brother to stop fooling around and put in his 120 per cent.

Then, Chrome turned to Senku with a beaming grin and chocolate-brown eyes gleaming with excitement as he asked, "So, what will you like to do, Senku?"

Said scientist rolled his eyes and replied sarcastically, "Why don't you tell me? It seems like whatever I say or do isn't allowed anyway."

The smile on Chrome's face dimmed and immediately, Senku felt a wave of guilt washing over him. Running a hand through his hair, he let out a defeated sigh and apologized for his harsh tone, "Sorry, I shouldn't have taken it out on you; knowing that it wasn't your fault and that you just got dragged into it."

Immediately, the brown-haired teen perked up again and waved away the other's apologies with a sheepish smile, "No, no, it's okay. It's not your fault too since you're here against your will. It's just that with the combination of (Name) and Kohaku, I don't dare to go against them."

Senku snorted at that image, but the corners of his eyes crinkled with fondness at the thought of his girlfriend despite still being somewhat mad at her, "They are quite the scary pair, aren't they?"

The two of them exchanged chuckles and after which, Chrome switched the subject to the upcoming war against the Tsukasa Kingdom and what was the next course of action. Seeing the glimmer of exhilaration in those chocolate-brown eyes and the wide grin threatening to break the teen's cheeks in halves, the scientist didn't have the heart to deny him.

It wasn't the original plan of stocking up on chemicals in his lab as he had planned, but it was still science-related. And so, Senku took the bait and for the next hour or so, the science users sat by the large tree; its bare branches casting shadows on their figures as they delved into the world of science.

After their conversation, the two just sat in comfortable silence; watching the other three training in the distance when suddenly, Chrome broke the bubble with a random question out of the blue.

"Ne, Senku, how did you and (Name) meet?"

Immediately, Senku's attention shifted to the brown-haired teen as he blinked, not having expected that at all. However, once the words sank into his mind, the scientist raised a brow and said, "Where did that come from?"

Chrome turned to look at his friend, his brows furrowing as he answered, "Earlier on when we were talking, (Name) kept popping up here and there. And I just couldn't help but be curious about how the two of you met. I imagine that she must've been the one to approach you first because you don't seem like the type to make friends. In fact, I'm surprised that you're even dating her."

At his last sentence, the brunette shot the scientist a teasing wink; the smirk on his lips widening when he noticed the twin spots of red appearing on the other's cheeks.

"I-," the green-haired teen sputtered, his arms flailing about as he tried to respond but he was too embarrassed and caught off guard by his friend's comment. In the end, he let out a deep groan as he buried his flushing face in his hands, "I wish the ground will just open up and swallow me whole right now."

Chrome lost it and started laughing, drawing the attention of Kohaku, Kinro and Ginro who were making their way over after deciding to take a break from their training.

"What got Chrome laughing like an idiot?" Kohaku asked, raising a brow in question while glancing back and forth between said brunette and Senku who was shooting daggers at the former.
