You caught the Hanahaki disease. Who is the one you loved? The Wind Pillars younger brother, Genya. You'd been avoiding everyone since you caught the rare illness.

Well, apparently the universe hates you, as you got paired with the hot-tempered Demon Slayer for a mission. Well~ The mission had been going well, and you masked your illness, untill it got so bad you just collapsed to your knees and broke out into a coughing fit. The flowers were clogging your throat and lungs.
