Okie here the addition be!!! Enjoy!! ;3

After racing to school in the morning you had no time for anything! You were hungry, needed a shower, and still had to babysit the Science Brat! You sweat dropped, then Light bulb went off in your head.
You could do all that at Senku's without him noticing, Duh! During last class normally you'd walk with Senku, but you could leave early and take a shower without anyone in the home and get dinner ready!
'Your so fucking smart Y/N! Bitch you're a natural genius!' You giggled to your compliment made to yourself making your way to school.

~Time skip Cus Science~

You rushed to Senku's house after you got out 30 mins early but getting to Senku's took maybe 10 mins, so great timing!
'Shit! I dont know what kind of Shampoo he has, well that doesnt matter now I'm already here. I'll use whatever I can find!'
You rushed upstairs to take a shower. You folded your uniform neatly and took out comfier clothes out of your backpack as the water ran to get hot.
"Haha! since Lettuce head isnt here imma use my speaker!" You picked out a song, took off your clothes, and hoped into the shower.
It felt amazing, so refreshing!
'So, this is Senku's shower?'
You blushed a bit, but shook it off.
"Pretty basic guy stuff, Some Axe and Old Spice... that's why he smells so good..." you blushed thinking about Senku taking a shower.
'Fuck! What are you doing Senku is the most logical, intellectual, aromantic person you've ever known, he wouldn't give two or ten billion shits about your feelings towards him..' you scolded to yourself.
'It's not like he finds you attractive anyway... he is just a really good friend though... so maybe that's all you need too be...?' Your heart fell to your feet as you thought that. It would be amazing to be with someone like Senku! He was intelligent, kind(when he wanted to be), loyal, honest, and actually remarkably attractive!
As you finished your shower you reached for a towel, but there wasnt one!
"Oh Shit!" You face palmed "They are all downstairs in the laundry! I can run down there quickly..."
Before you could run out of the bathroom, IT OPENED WIDE!

There he stood! Senku was wide-eyed with his mouth open in shock! That was the first time you've seen him blush!
"Ummm... welcome home hehe..." you try to laugh as you scratch your head and blush brightly too.
It was a couple of seconds of Senku just staring at your naked figure with a shocked red face.

~Senku POV~

I waited for Y/N to walk with me to my house, but she must have left early to prepare dinner.
I shrugged and put in headphones Y/N gave to me, some of her music was not as terrible as I had first assumed.
I got to the house and walked to my room, but I noticed smoke? Coming from the bathroom! I quickly opened the door to see if there was a fire, but the only thing thay was on fire was me!
Y/N was naked and wet! All I could do was stare, I've never seen anyone else naked before, definitely never a girl!!!
"Ummm... welcome home hehe." She looked away blushing as much as I was!
'She is so...Wait, why are you blushing!?!?'
My heart beat was crazy, I felt so funny! I didnt want to look away... why wasnt she trying to cover herself!?!?!
"S-senku could you get me a towel from downstairs... please?" She asked as she was shaking from the cold.
"U-uh yeah...sure..." I ran downstairs and grabbed a towel and gave it too her.

~Reg POV~

Senku came back with a towel, but didn't leave as I took it away from his hands.
That same feeling sparked in both of you, as your gazes fell on each other.
He was so cute, but why was he blushing? He never shown any emotion quite like this before.
He just stood there in the doorway still shocked and red.
"Are you just gunna stand there like a deer in headlights, or are you gunna close the door?" You asked quietly.
"O-oh... yeah... sorry."
He apologized?
"U-ummm before I do go could you answer a question?"
You nodded.
"Why didn't you cover yourself when I barged in?"
You pondered his question for a second, then you smiled brightly at him.
"Well... I didn't feel the need too Senku. You aren't like some guys... I-I mean it's not like you like me or a pervert or anything like that! It was an accident too, I should have locked the door! Or at least told you I wanted to take a shower, I'm sorry!" You bowed, holding the towel in front of you.
Senku's expression went back to normal as he smirked at you.
"So you're comfortable around me... well that's good to hear. Still, you ten billion percent caught me off gaurd! Next time just tell me before you take a shower, HA! I thought the place was burning down!" he scolded as he left and he closed the door. You took a deep breath, shook off your thoughts, and got dressed.
~Senku's POV~
I got to my room, closed the door, and put my back to the door and slid down to sit on the ground.
'Out of all my inventions I know how each of them work, she is ten billion percent not like the rest.  What was that feeling when I seen her like that? We are both so different, we shouldn't even know each other because of that fact! I do find her attractive!' His blush came back to his cheeks.
"Y/N makes me feel happy though... would she ever see me as more than a friend one day?' His mind raced with questions, but one answer kept popping into his logical brain.
"She would make one hell of a wife one day..."
