Hi, I'm looking for a manga about an man, whose wife died not long ago in a fire.She had memory issus, Alzhimers? He retiers from his job and start living alone, then his wife suddenly appears as a ghost, invisible to others but not him, that redo all her steps as she goes on about her day, she does not react to him in any way. He begins to follow her in her steps and he learns how to cook, wash, clean, shop and more. He remiss how much he didn't have time to spend with her when she was alive. It goes on for a long time until the day she dies and he see her spirit as she tries to crawl away from the fire and dies. It cut to years later to his funeral where a friend, he had asked to place a cherry tree branch? or something of a flower, on his grave and you later see him reunite with his wife with the branch? Flower?
It was many years ago I last read the manga and don't remember the name. I think it was a one shot och very few chapter. If anyone knows and would write the name, I would really appreciate it.
