The babydoll.

Christopher Bangchan & Minho (Manipulative and Dominant Power): In the story, the two brothers are depicted as leaders of an empire built on wealth, absolute control, and an illegal/secret order (rigged gambling, manipulation). Physically well-built and mentally cold-blooded, they operate like "predators" cornering their prey.
Hwang Hyunjin (Vulnerable and Desperate Situation): Having recently graduated from university, he is a desperate character in a severe financial bottleneck. His delicate, striking, and vulnerable nature makes him an open target for the two brothers' manipulation and desire for control.
