เสียงกล่อมใจในคฤหาสน์

21-year-old hypnotherapist Lily becomes the new maid at the wealthy Zimmer family's mansion to earn money for her sick sister. But she soon discovers that this high-paying job is far more complicated than simply treating insomnia. The family's fourth son has suffered from insomnia for 19 years and refuses to trust anyone. The sixth daughter, shattered by her fiancé's betrayal, is torn between love and hatred. The seventh son, driven to the brink by his controlling mother, turns his pain against himself. Meanwhile, the domineering heir keeps pushing Lily to her limits. With nothing but her healing voice and unwavering devotion, Lily slowly breaks through their defenses and heals the hidden wounds behind the family's perfect facade.
