Huang Qiying, the eldest daughter of the Huang family, is bright, flamboyant and domineering. She is a famous "rose with thorns" in the shopping mall. The experience of losing her mother when she was young made her accustomed to building high walls with sharp edges and hiding her softness until nothing leaks out. One time when she returned home by chance, she bumped into Lin Yu, the second young master of the Lin family - a young man from an aristocratic family who looked as gentle as jade and had a slight sense of alienation. But no one knew that this seemingly cold and noble second young master Lin had a paranoid possessiveness hidden in his bones. When she forcefully breaks into his world, the game that begins with conquest gradually evolves into an endless entanglement.
