Naga Kembar

When the Dragon Commander, protector of the kingdom, is killed in action and goes missing, his general Seraphina is forced to find Alex Smith, who looks exactly like him, to impersonate the Dragon Commander and prevent traitors from assassinating the King. Alex Smith reluctantly agrees, but is constantly questioned and humiliated, which Seraphina skillfully resolves each time. However, Alex Smith discovers that he seems to have an innate understanding of the Dragon Commander's abilities and begins to question his own identity. On the day of the state banquet, the mastermind Yun Junyang finds evidence that Alex Smith is not the real Dragon Commander. Just as Alex Smith is unable to defend himself, the real Dragon Commander appears, executes the traitor on the spot, and reveals the truth: Alex Smith is the Dragon Commander's younger brother.
