You Said You Were Away on Business, but I Received Your Ashes

Looking for Tragic BL With a Bad Ending! A Bad Ending! A Bad Ending! Make It Hurt!

Two Male Leads, One Frail and Sick from the Start; Either a Tragic or Happy Ending Is Fine

Looking for books like After Getting a Terminal Diagnosis, I Lay Flat and Waited to Die, and My Ex-Boyfriend Panicked. Preferably completed, not too long, and ideally something I can finish in three days. The male lead must be physically ill, preferably desireless and detached. No mental illness or depression, just an obvious physical illness.
