Christopher Bang is a powerful mafia boss who lives in a huge mansion surrounded by security and strict rules, where only people of extreme trust are allowed to enter, functioning as a small world isolated from the rest of the city. You are the daughter of a longtime maid of the mansion and practically grew up there, accompanying your mother at work and learning from an early age how everything functioned; over time, you followed the same path and began working in the house, becoming part of its daily routine. To Christopher, you had always been there but were never truly noticed: he knew every detail of his business but completely ignored those who took care of the house he lived in, until an ordinary day-to-day situation finally makes him notice your presence.
