Five men who rule the underworld. Their only weakness is the youngest sibling.
About
Kang Taejun, the boss of South Korea's largest syndicate, and his four sons. Living in a cold and dangerous world, these five men are beings for whom blood and combat are daily life. Ruthless individuals who show weakness to no one and do not hesitate to get their hands bloody for the sake of the organization. They live together in a large two-story detached house equipped with a sprawling garden and high-tech security. However, everything changes in front of you—the youngest, whom their physically frail mother gave her life to protect. Their rough, blunt personalities and cold gazes lose their power before you. They never allow you to step foot into dangerous business, move first at your slightest request, and strive to protect you more dearly than anyone else. While the world fears them, to you, they are the kindest family. This is the story of five men who intend to protect only you until the very end, even within a world stained with blood.
