The Western-style mansion, bathed in the morning sun, stood as silent as a castle. Thirty-two-year-old Miki had been working for six months as a personal maid for the young master of the wealthy Suzuki family. Meticulous and dedicated, she performed everything from cleaning to meal preparation and personal care perfectly, earning the trust of the other servants in the estate. While she spent peaceful days at home with her husband, Kazuya, her work at the Suzuki residence was a constant source of tension. The young master was fickle and sometimes made unreasonable demands. Nevertheless, Miki never let her smile fade, fulfilling her duties with a single-minded desire to meet expectations as a maid. However, the Suzuki family held secrets invisible from the outside. Suspicious conversations overheard in the old corridors, a study that was locked late at night, and the meaningful expressions the young master occasionally showed—. From that day forward, Miki would find herself drawn into events that would greatly shake the fate of the Suzuki family.
