Sorry if Kanao seems a bit out of character here, it ended up like that for three reasons :

1 — She's kinda of a hard character to write in the start, since she rarely expressed emotions.

2 — The way and reason she fell in love with Tanjiro were too specific, and I wanted her to start to like Y/N for a different reason then “oh she accidentally stole tanjiro spot in the coin thing” 

3 — She also has very little appearances through the manga and such, so I wanted to make her have more fluff moments with the reader.

◇♡◇♡◇

It has been some weeks that they have been staying in the butterfly mansion, and the result of this was :

Aoi was tired.

Simply as that.

The three boys were just too much work for her, and each day turned into a new fight for making Zenitsu drink his medicine.

Things started to get a little better when Y/N healed enough to be able to walk again, she would always be around to help even in the most boring tasks like doing the laundry, she also got interested in learning first aid measures, and has been learning it from Aoi and the other three girls.

She got good enough at it to even be able to help to tend to some demon slayers, but only to the ones with superficial injuries.

"Kana! Remember the other day when I asked you which food you liked, but your coin said for you to not respond?"

Y/N calls out to Kanao as she sees her standing in the garden.

She blankly looked at her before nodding at her question.

"I have an idea! Why don't we try cooking together, and you point to the food you like the most?"

This was an excuse Y/N made to spend time with her. Kanao is adorable, so she would be delighted if they could be friends.

Kanao then threw her coin, nodding after seeing the result.

However, after they entered the kitchen, it didn't take long for everything to turn into a mess, Aoi opened the door in an exasperated way only to see the two girls covered in flour.

"Wha- what are you two doing?!"

♡

"Geez, I kind of expected it from you since you are always spending time with these three childish boys, but from Kanao?! You really are something-"

Aoi rambles while rubbing a towel on Y/N's wet hair. Even though she was complaining, she was drying the girl hair like a mother.

"Thanks for drying my hair!"

"I… I'm not doing this for you! J-just stay quiet!"

She quickly exclaims with her face red, even though her tone was mean, she started to rub her hair more delicately. 

♡

It has been three days since the flour incident, Y/N relationship with Aoi drastically improved, and she was still trying her best to get closer to Kanao, she constantly tried to talk with her, but their conversations always ended up cut short because of Kanao's coin saying for her to not talk.

"I DON'T WANT TO DRINK THIS, IT'S TOO BITTER! IS THIS REALLY ENOUGH TO HEAL MY LEGS?!"

"Here Zen! I will feed it to you, so say “ah” okay?"

"B-but….it's bitter! But… Y/N's going to feed it to me…but it's bitter- but Y/N-" Zenitsu started to mumble to himself.

She inclined her head with a sad expression.

"You don't want to?"

"I'LL DRINK IT!"

Thank god Y/N had enough mercy to deal with Zenitsu in Aoi place, convincing him to take his medicine every day was really a pain in the ass, so she was somewhat grateful for him being such a simpleton guy.

"Oh, there's tempura for lunch today." Aoi comments while changing one of the bedsheets.

"Really?!" Y/N perks up from beside Zenitsu, almost spilling the medicine she was feeding him.

"Oh, sorry!"

"… I-if you like tempura that much, then I might put some extras for you…" She says, her cheeks red while she avoided eye contact with Y/N.

"Thanks! I'm really looking forward to it!"

"You can have my portion too, Y/N." Tanjiro says with a gentle smile as he was having his bandages changed by Naho.

"Me too! You can have my portion too!" Zenitsu exclaims with his mouth full of medicine, Aoi then finishes making the bed and leaves the room while letting a small “humph” escape from her, she really doesn't even try to hide her distaste for them anymore.

"Inosuke, how are you feeling?" Y/N asks, Inosuke being silent all the time was too weird for her, so she was trying her best in motivating him to talk.

"I'm fine…."

"Do you want me to share my lunch with you? Since I am your underling and all."

She honestly doesn't even know when she ever agreed to be his underling, but he looked quite happy when she called him lord inosuke before, so she thought it would help to cheer him up if she refers to herself as his underling.

".....it's fine, my throat hurts too much to eat anyway…"

"DID INOSUKE JUST REFUSE FOOD?!" Zenitsu exclaims from his bed.

"OH MY GOD, IT'S MORE SERIOUS THAN I THOUGHT!" Y/N also exclaims.

A small knock to the door grabbed everyone attention, as Kanao entered their room.

She silently stood there before throwing her coin in the air, her eyes shined for a split second after she saw the result.

"Y/N…do you…want to have lunch with me?"

Actually, it was Aoi that asked her to bring the girl to have lunch with her, Niho, Kiyo and Sumi, but she still wanted to ask in this way for some reason, though she couldn't pinpoint why.

'Why do I feel like Y/N is seducing all the cute girls?' Zenitsu thinks to himself.

"Of course!" She smiles happily, completely forgetting about her intentions of helping Inosuke, her mind was too busy filled with food to care.

Y/N then quickly took her hand, excitedly dragging her outside the room, completely abandoning the trio.

"So, where are we going to eat?"

"..... On the last room in the corridor." She talks.

Without throwing her coin.

"Eh?! Did you just make a decision without the coin?!"

Kanao face suddenly goes red, she started to look at the floor while stuttering.

'I-it's just that…. I would've had to let go of your hand to throw it, so…."

HOW IS SHE SO CUTE?!

"Don't worry! I will hold your hands whenever you want to, so you don't need to force yourself to make decisions without your coin!"

"…"

She starts to reach to her pocket, but stopped halfway through her action, before silently speaking :

"People get tired of me pretty fast because I can't make decisions without that coin. I don't know how to explain this feeling, but…my heart hurts when I imagine you getting tired of me too…"

"Why would I? I really like spending time with you! Even though I get a bit sad when you can't respond to me because your coin said so, I will always find another way for us to talk! The cooking thing didn't really work, but I will find another-"

Kanao silently puts her hand to her chest, right above her heart.

"Kana? Are you feeling pain or something?"

"No…it's just….it always felt like there was a knot in here, but…it suddenly alleviated…what does this means?"

"I guess it means you are happy."

"… Happy?"

She furred her brows while saying the word, like it was an unfamiliar one to her. After a while, she silently speaks up with her cheeks flushed: "If it's fine by you…could we have lunch together tomorrow too?"

"Of course!"

"And after tomorrow?"

"Yeah! Any day you want!"

A smile slowly appears in her face.

A genuine smile.

"… I will look forward to it."
