It's been a Few weeks since the Mugen Train incident and since that day you gotten close to Tanjiro and Nezuko,you're only been the medical aspect of the butterfly sisters being called the butterfly brothers,on this specific mission. Nezuko wasn't brought with Tanjiro,and You were put in charge for her,you promised to tanjiro that Nothing bad will happen to her.

"Hmmmm"

You heard a soft mumbling beside you as you saw Nezuko tugging on your pants it seemed that she was bored, you decided to put her in her box until you can figure something out,after spending two whole hours you finally figured out something how about a sleepover with nezuko wearing a dragon outfit but realizing it was just gonna be you and Nezuko felt... weird to you but shaking off that feeling,you made her a dragon pink and Yellow suit you didn't realize how oversized it was but she probably grown into it

"Mmm?"

Nezuko was confused by the oversized dragon outfit until you explained you're sleepover plan luckily Nezuko was able to understand human words which made this all the way better. She seemed understand as she started to change you as the kind gentleman you are walked outside and wait until she was done. After 4 minutes she came out looking adorable... but it also looked sexy at the same time

"GRRR"

She intimated a dragon noise that was cute as she tried to do the dragon claws but the suit arms was too big so it just only looked like she was flapping her arms around
