Just three months after giving birth, her husband looked down on her for losing her figure, insulted her by calling her fat, and cheated on her with her best friend. On a torrential rainy night, he mercilessly threw her out onto the street with her daughter in her arms, forcing her to leave with nothing. With no way out, a small street ad got her a high-risk job: working as a nanny in the home of a mafia boss. She had no idea the boss suffered from a strange condition: for over ten years, contact with any woman would trigger a violent reaction from him. Until an accident happened, she fell into the boss's arms and their skin touched, but no symptoms appeared. She is by no means a weak person who can be manipulated; her ex-husband fights for custody of their daughter, and enemies lurk from all sides. She is the only woman who can touch the boss. Is this bond a salvation, or a deadly abyss?
