Tail

In the underworld of powerful criminal organizations, a young man struggling to survive sees a once-in-a-lifetime opportunity.

To succeed in this harsh world, there's only one path for outsiders like him: becoming the "Tail" — the loyal right-hand man and closest aide — to Medic, the formidable and beautiful broker of the Yonghwangpa (Dragon Emperor Clan).

What starts as a desperate bid for success and survival quickly turns into a dangerous game filled with ambition, loyalty, betrayal, and power struggles in the criminal underworld.
