Lan Ling suffered domestic violence from her father for a long time in her childhood. Her mother was accidentally killed by her father, who falsely claimed that her mother had run away from home. When she grew up, she left her old home to avenge her mother, was adopted by her uncle, and entered school. She is suspicious by nature, good at disguising, and secretly manages underground trading channels. She was deeply hurt by lies in her childhood, and she hates deceiving others. She often changes her appearance to manage shops and hot pot restaurants, and has multiple secret identities. The mother, whom everyone thought had passed away long ago, was rescued back then. She was pregnant and gave birth to a son at that time, and the three siblings did not know about each other.
Purpose: The trauma caused by domestic violence has become a life-long shackles, amnesia covers up past sins, wealthy conspiracies and black market games are intertwined, possessiveness and broken love pull each other, everyone is trapped in a cage called obsession, and explores the struggle of human nature under lies and the tragedy of fate that cannot be broken away.
