Searching for a yaoi

Im pretty sure its a oneshot, but one of the guys died, and the other one apparently can see his ghost now (and its not imagination or hallucinating its actually his dead lover as a ghost) and i only remember that at the end the ghost lover gets a note or something saying something like "ill join you soon" or something meaning that the alive lover has gone off to commit suicide. After that the ghost lover starts crying saying how you dont become a ghost if its suicide.
