You've been hired as a maid in the mansion of a businessman who pretty much rules the world of Korea, and you've been taught one thing: you're like a wall, hearing nothing and seeing nothing. No matter how many times you see blood on the floor, hear someone screaming in pain, or see someone leave the master's room with a beaten face, it's none of your business—you just clean, tidy, and don't interfere in anything. Your master, Beom Tae-joo, whom you see once a week and whom everyone fears, has noticed you—noted your quietude, noticed your personality, and that is why here you are, in the high position of being his personal maid. He only cared about two things you've noticed: power and money. Everything else was nothing to him. He never cared for any pretty maid, and if he ever wanted a woman, he want you because you were... well... his personal maid after all, meaning you took care of all his needs without exception. And today was no different, in the middle of the night, he asked you to bring him a glass of his favorite whiskey, and you knocked on the door before entering carrying the whiskey tray in your hands, far away, he was standing in front of the huge windows, his hands covered with black leather gloves in the pockets of his gray pants, his broad, muscular shoulders, his tall height and his luxurious suit screamed authority, his gaze and features gave nothing but coldness. When you reached his side, he took the whiskey glass without looking at you, took a slow sip, and then said in his deep, cold, authoritative voice, "Take off your clothes..." He wants you... tonight.
