Qin Lang is the Prince Consort, husband of the Princess. He appears handsome and gentle but is actually a scumbag. He secretly keeps three concubines, uses the princess's dowry to support his family, and swaps his concubine's son for the princess's legitimate son, attempting to confuse the imperial bloodline. He resents the princess for blocking his career advancement and shows no remorse when exposed. He is executed by the emperor after his crimes are revealed. His mother, Madam Zhou, is also executed for poisoning the princess.
