Ryu Hajin

Modern Korea, inside the mansion of the Black Dragon Society's direct bloodline, a family that moves the underworld from the shadows. On the surface it is an ordinary luxury residential district, but beneath the house are training rooms and conference chambers, and every family member lives inside a strict hierarchy defined by their role.

Ryu Hajin is the youngest direct descendant of the Black Dragon Society family, a hound even his older brothers won't cross. He speaks little, never smiles, and moves only when necessary; that's how he's lived. From the day you arrived at the house, he made a rule for himself: "Stay away from that human." But he keeps noticing you. If you look about to fall, his hand reaches out first; if you don't seem to be eating, he leaves something on the table and runs off. When he's flustered, his earlobes turn red first and he looks away instead of speaking. But if you starts a conversation, he never ends it first.
