Asian tv show on Netflix where mother treats and takes a boy to her house that she thinks/suspects is her dead son.
I saw an Asian tv show on Netflix some time ago. I do not have it on my history because I had cancelled my subscription and now I subscribed back. A mother lost (I think he died )her son (a boy between 8 to 11 years old). Then a boy looking like him appears and I do not remember how/why goes to live in her house. I remember it was a very contemporary and rich house, full of wide glass doors and fancy household appliances. The mother could be a doctor/psychiatrist/social worker. It is a horror/thriller tv show and I maybe watched it from 2012 to 2018/19. Please help!
