Illogically Logical (Senku x Fem!reader)

        The night sky had shown its face, and Senku was happily collecting sulfur with (Y/n) while Taiju and Yuzuriha were taking a bath in the hot springs, with a makeshift divider to keep the two sides separate. It may be 3,700 years later, but privacy is still a thing, along with common decency.

"You're like a child in a candy shop," (Y/n) laughed softly, sitting next to Senku. She had her back to Taiju since they were gathering sulfur from the boy's side of the spring. Besides, she's seen a boy's privates before, she did take biology when she was 7 from her mom. Besides, the textbooks do not censor anything, so it didn't matter to her. If she was going to be a doctor, she can't be squeamish around the private parts of her patients. "The only difference is that you don't prefer candy."

"What can I say," Senku chuckled, still hacking away happily. "With this stuff, we can make a boatload of stuff! With this baby, we can make flares for secret codes if we can get our hands on some stuff that will change the color of the fire."

"Unfortunately I don't remember if gunpowder has any medicinal properties that can aid us, aside from possibly killing someone from consumption," There weren't a lot of studies (Y/n) can remember from their time where gunpowder was used for any sort of healing, so that was out a no go until she can get clear data on it either having some or no healing abilities. That, and why consume gunpowder? "Anyways, Seku, are you going to take a dip in the host springs? It's good if we can take a bath and wash off some of the germs, it will increase our chances of staying healthy."

"Nah, you can go join Yuzuriha and Taiju," Senku just kept hacking away and getting as much sulfur as his little heart desired. "I'm sure they'd love your company."

"They're talking about romance stuff, and I'm not talking about that," The physician stood up and started dusting off the dirt from her outfit, trying to get as much off as she could. "Come on Senku, you need a bath. It'll keep us healthy."

"No."

She grabbed him by the top of his head, and redirected his gaze to her, a creepy smile on her face, one Senku is all too familiar with. It was her passive aggressive smile. "Well then, I guess I'll just have to make you. Doctor's orders, Senku."

"I can't believe you're making me take a bath," Senku groaned, sitting in the water of another hot spring. "I'm not just some little kid that needs his mom to tell him what to do."

"Even so, you should at least take one," (Y/n) said, sitting in the water as well. Both didn't bother putting up a divider, considering Senku studied biology with (Y/n) when they were younger, so the private parts of the opposite sex wasn't going to bug them. Besides, they did give each other some privacy for when it came to undressing and when they plan on getting out. "Doctor's orders, Senku. Besides, we haven't had a proper bath since, oh gosh, the day before I was petrified for me at least."

"I took one in the morning, so it was a day of petrification for me." Senku leaned against the rocks, relaxing. He will admit, taking a bath in a nice hot spring was something his muscles needed.

The two sat in silence, but it wasn't an awkward kind of silence. Both are used to this kind of atmosphere, considering they've been working together since elementary school, making sure they stick together when it comes to partner projects, along with not wanting to be paired up with others because they liked working together. That, and Senku thought the other kids were too stupid to be his partner.

"Hey (Y/n), is there anyone you want to revive once we manage to get our hands on some miracle fluid after Tsukasa has been defeated?" Senku asked, looking over to his friend who was sitting across from him, her back against the wall with her upper body under water.
