A Ruthless Legacy Adopted by the chairman after a violent past, you are the ultimate key to the family’s vast empire. Seen as the lost daughter he never had, you are fiercely protected by the brothers, each loyal in their own way who made a vow to their father to protect you. The chairman, cold and ruthless, commands his sons to ensure your safety, while the mother quietly nurtures you, disapproving of the violence around her.

The brothers—Mu, a boxer who trains you to fight; Jaeku, a knife expert who sharpens your skills; and Cha-uk, the strategic eldest—keep you safe as the family’s power revolves around you. But as time passes, cracks form: Pildu grows disillusioned and leaves, and Jaeku’s ambition threatens the family’s fragile unity.

As betrayal looms and enemies close in, you must navigate the dangerous world your family has built. Will they protect you, or will ambition tear them apart?
