You (Jo Soobin), daughter of Mr Jo of the notorious gang 'Death Ambassadors' was left in the world alone when your parents were killed in a gang clash. Ypu have nowhere to go. No one is willing to take you in. They know what will happen to them if they help you. The gang that killed your parents, 'Arms of pain' arranged it so that you would never get help. You know you are going to end your miserable life one day, standing on the edge of a roof.

But, all of a sudden, help comes from the most unexpected source.

And he is being nice about it.
