[Perfection] Yandere Platonic Kny x Child reader

what?...

Tanjiro's eyes would immediately widen at the sudden vulgar language she used.

"What did you say!?"

Tanjiro would question while he grabbed her shoulders and shaked her.

"What does fuck mean?.."

Tanjiro would look dumbfounded before he would have a serious look on his face.

"Don't ever say fuck, okay?.."

Tanjiro would look expectantly at her awaiting her response.
"Why?"
Tanjiro would sigh at her response.

"Cause it's a bad word"
He said hoping she wouldn't ask anymore.

"Why?"
Tanjiro would take a deep breath.

"It has a bad meaning and you should just never say it, okay?"

"Why?"

"Cause it's a bad word and you shouldn't say it."

"Why?"

"It has a bad meaning!"

"Why?"

Tanjiro would begin to get frustrated. Not mad though, he could never be mad at you.

"How about we talk about this later?.. it's pretty late right now and you need your rest."
Tanjiro said while standing upp with her in his arms. He would then head back inside. His soft footsteps could be heard through the hallways once again. He would finally reach their room
Though he was nervous, would their argument continue?..

He decided that moment it wasn't a question, he would look after you. After all only he could do it correctly.

The door would slide open softly as Tanjiro would walk in. He could feel Inosuke's gaze on him. Though he noticed Zenitsu wasn't in the room.

"Where is Zenitsu?.."

"Monichi is searching for yall! But I the great Inosuke knew you would come back soon so I waited!"

Inosuke would say while beaming with proudness for himself. Though what he didn't realize is that is the most practical option almost anyone would have chosen.

Tanjiro would sigh in acknowledgement. He already knew Zenitsu would be like a mother hen searching for them. He most likely is going to wake everyone up.
Tanjiro would then just lay down on his bed while still holding {Name}.

"You comfortable like this?"
Tanjiro would quickly ask. He needs to make sure she is comfortable.

{Name} would just hum in acknowledgement. Their lack of sleep was starting to catch up with them.
Tanjiro would be satisfied with this answer and he would fall asleep in merely seconds.
(In my personal experience, whenever I cry I am immediately really tired afterwards. How about yall?)

He was shortly after followed by {Name} who also fell asleep.
Best to fall asleep before you have to suffer trying to fall asleep with Inosuke's snoring.

Inosuke would fall asleep around the same time Zenitsu would come back to the room.

Zenitsu would be freaking out because he couldn't find {Name}.  Tanjiro wasn't as much as an issue. He would get more time with nezuko and {Name}.  Mostly {Name} though.
