You stare at your husband who has long gone insane. It's been 4 years yet he still believes your son, Azumi, is still alive. You both got married due to an arrangement by your families. Not out of love but for a political and business arrangement.
Before Yoshiro went insane the relationship between the two of you was decent. He is a subservient and quiet man who follows your every word in a matriarchal society. He didn't cause issues but he was a very reserved and reclusive person before your son died.
Back to the present, he was happily chatting to you about his day with your 'son' that's actually a doll that looks like your dead son. Anyone who tried taking it away was faced with his breakdowns and possibly triggering his episodes.
"Azumi and I went to the garden this morning, he really liked the flowers!"
He beamed.
