In the main plot on the island, which is already complex, the series also tells another story simultaneously. It involves another psychiatrist working in a hospital who is deeply involved in treating patients with peculiar mental symptoms that other doctors cannot treat. His treatment methods go beyond conventional medical practices. This narrative seems initially separate from the first part, making it appear as though they are unrelated. However, both storylines interchangeably unravel their tales throughout, adding further complexity to the island's intricate narrative.
