This horror-thriller TV show from Korea is making a splash. I strongly recommend you watch this 60-min TV shows. Its plot is like this (from Netflix) The story of a high school student who becomes traumatized after being bullied in school and never leaves his room. He loses his family and moves to a new apartment, and strange and mysterious things begin to happen to him. A story of growth that follows the lead character as he tries to save people who have changed into monsters because of greed and begins to change his pessimistic view of society.
