You had been going through the loss of your father, attending his funeral alone. Your family didn’t care enough to even bother, and your ‘friends’ were all busy.
You sat by his grave for hours on end, sobbing your lungs out until you were too exhausted to make noise. You fell asleep in the grass beside the engraved stone, body curled up.
Yoriichi had just been banned from the Demon Slayer Corps, walking through the forest as he thought about what to do. He came across the flat area of land where your father’s grave was, curious as to what it was.
That was, until he noticed the curled lump you were on the ground. It was raining hard by now, and it felt immoral to leave you there.
He attempted to wake you, yet you didn’t stir, so he decided to just pick you up instead, holding you in his arms as he thought about what to do with you.
