When Tanjiro started staying at the butterfly mansion, he saw you as Aoi. This kind boy treated you with his usual gentleness, but you blushed every time. These little interactions between you had made you both feel something for each other. The dynamic between you was so sweet, you would take care of his wounds and in short, he would love you with all his heart.

One day he left the butterfly mansion to go on another mission, and barely a week later, you see him walking towards the butterfly mansion, injured and limping, using the hilt of his sword as a walking stick, smiling softly when he sees you.
