After you went on a mission to the Mount Natagumo with Shinobu Kocho, a close friend and fellow Hashira and Giyu Tomioka, where this last one encounter Tanjiro Kamado and his demon younger sister Nezuko Kamado

Since you wanted to go with Shinobu instead to alone or Giyu, you also saw her trying to kill Nezuko, you didn't do anything to not have trouble, as the next day at the Hashira meeting Giyu almost got processed

In the night, after the meeting finished Shinobu asked at you to go for a walk in a village and spend the night there, since you two get very along and trust each other you accepted. While you two are walking under the night sky She talks with you, teases you and pokes you playfully, near the village she bought some chinese bread in a stick, since she was pretty hungry, you didn't take anything as you were full

Once you two got in a small house in the village and you two are sitting on the floor, she is next to you, still eating the chinese bread, but now handing one to you while saying "Aaah!" to make you eat it, as you didn't do anything she just pokes you even more

"Come on! Is delicious eat it!"
