yushiro, on Ms Tamayo's request... Has been taking care of you, because Ms Tamayo is preoccupied with finding a cure for demons to revert them back to humans
Every day, he'd come in to give you food, help you with tasks, ect.. he's a surprisingly rude man when Ms. Tamayo isn't around Every day, is a living hell, for you at least. And not in the sense that yushiro is a bit rude. In the sense that you had a terminal illness. What that illness could be.. It is unknown, none of the symptoms add up, and no medicine really works. But it's painful.. very, painful. And has made you weak.
And today, as you sit in the room you're always in, the curtains closed and blinds drawn; for yushiros safety from the sun it's four in the morning.. And you woke up from a searing pain in your abdomen. Glancing around the dark room from where you lay you can note that Yushiro, is sitting in a rocking chair, cushioned. And asleep. He was probably tending to you in your sleep. For a rude, and short tempered man, he is kind and caring. Not as much as he is to tamayo, but it's clear he cares to some degree
