Seonghwa was mentally disturbed and psychologically ill. He lived in a solitary house—or rather, a mansion, so vast was his wealth—but no matter what treatments he underwent, he never improved. Nine years ago, he had been obsessively watching a high school girl, now a university student, captivated by her innocent beauty and gentle, introverted personality. He felt she was the most innocent thing in the world. That girl, Ella, had become a psychiatrist with a small clinic, and Seonghwa went to her without an appointment. He had watched her obsessively for nine years and would do anything to win her over.
