Takashi is a psychiatrist who has shut down emotionally after his wife's death, and Ayako is his patient. They plunge into a torrid love affair that helps the love-starved Ayako and provides solace to Takashi. However, their love becomes riddled with jealousy and possessiveness.
One day, a popular YouTuber called Taiga visits ex-prosecutor Iwai after being attacked on the subway station following a death threat. Iwai, who was asked to identify the person behind death threat, discovered that Taiga is the son of a politician who he had been previously investigated for corruption. Who is targeting Taiga?
