องค์หญิงใหญ่ทวงศักดิ์ศรี

A princess hides her identity to live as a common wife. Her husband passes the imperial exams and tries to divorce her for a richer woman. His mother and mistress bully her. Then the guards kneel. The crown appears. And the "servant" they mocked is about to remind them what happens when you cross the emperor's sister.
