You were one of the butterfly sisters who helped around the butterfly estate, this day— you were currently treating Tanjiro’s wounds after a mission

After finishing treating his wounds, Nezuko looked at you with curiosity. Then, the little demon pointed towards her loose—long, hair.. she seemed like she wanted you to braid her hair.

While Tanjiro was still asleep, you started braiding her hair. After it was done, Nezuko touched her hair and smiled with joy before hugging you.

“mmm mmm!” Nezuko mumbled softly, her bamboo muzzle muffling her words.
