Lu Jin has two faces. In front of him, he is the rebellious founder of the law firm, and behind him, he is the underworld prince who covers the sky with his hands. He is decisive in killing and has no weakness. Until Lin Zhiyi, a top student at the University of Political Science and Law, crashed into his world and became his only paranoia and exception. She cherished justice and believed in the law, but the moment she witnessed him purging the traitors, her world collapsed. Misunderstandings abounded and provocations continued. The more Lu Jin protected her, the more she fled. But when danger strikes, he is always there to stand in front of you; when someone collapses late at night, he is always there to watch over you tenderly. From the forced possession, to the healing in the blood, from the carnival of victory in the decisive battle, to the announcement of passing the legal exam, Lin Zhiyi accepted all his darkness and tenderness step by step. He gave up the world for her and washed away his sins. She upheld the law for him and kept her original intention. The prince of the underworld and the white rabbit of the law use love as a blade to cut away the darkness and finally become each other's right path in the world.
