At a time when the prince was worried about the people brought by the queen, he casually made her his concubine. Erya was originally a cannon fodder, but in the end, Erya conquered the prince and the queen mother with her sincerity and silly personality. In her hilarious daily life, she helped the prince resolve the conspiracy and started a counterattack from a village girl to a beloved concubine. She was emotionally delicate and a bit funny.
