Blyss's manga / #Creepy(1)

Chapters 1-4 were stellar, made me tear up even (which is hard to do)....I love a good "ghost, but alive" story, but this ends up being "ghost, but alive and a kindegartener" Sure nothing blatantly happens between the adult and child when the adult is aware of the child's age, but thay doesnt take away the fact that sex happens between an adult and a person with the mental age of 6 at the most. Either suffering mc has to find a new love, grooms the child to be his lover as an adult, or becomes a pedo. None of thos are happy endings. There was literally no need for the living ghost to be some random kid. There was even mention of a "girl" first love that could have been reworked to just be an overly pretty boy who then becomes a living ghost and reencounters the mc....I am really annoyed at the ending of this story. It just ruined the whole story for me. Also the mc has to be around 25 at the least considering all he went through....and the fact that he's a dentist. That means there is a gap of almost 20 years.....and should wait almost 15 year for the boy to become an adult....at which point he will be at least 40, while his child bride will be barely 20. Ugghh it just reeks of grooming (even if it isnt predatory in feeling it is still grooming), and even if he stays away from the child entirely he still has 15 years of pining, sure he could sleep around to fulfill his needs as an adult man, but where is the romance in that. I am really curious about who suggested this as an appropriate ending, why they suggested it, and who the fuq approved it...
