How do you say something to the deceased?

Akari, who got a job at a funeral home, found herself witnessing her very first "funeral". She will get to see things like: an old woman with dementia who lost her husband, heading to the coffin containing her husband and asks him what he'd like to have for dinner; during the funeral of a head of a household who jumped in front of a train, the attendees secretly gossiping about the cause of suicide; The funeral of a beloved pet whose owner appears to be going crazy; A huge commotion at a funeral involving a big, extended family... Everyone is mortal. At the final farewell in a funeral, it's to each their own; it's a time when various emotions are overflowing. This is a realistic funeral drama drawn by the artist who formerly worked at a funeral home!
