Rain, a kind-hearted and generous teenager, lived a lavish lifestyle, often going to bars with her friends. Her world turned upside down when she woke up one day to discover that both her parents had died. The loss of her parents profoundly changed Rain. She became the opposite of her former self, standing alone in her house for hours, isolating herself from her friends, and sinking into deep depression. Her grief was so overwhelming that it began to manifest in recurring nightmares. Concerned for her well-being, Rain's attorney, a close friend of her late father, sought to find a psychologist who could help her. However, Rain's refusal to speak drove away many of the professionals. That is, until a young and bright psychologist named Yuan was hired. Unlike the others, Yuan's approach would change everything, bringing hope and light back into Rain's life.
