In the first episode of Princess Zhu Huan, two people were put in prison.

Swallow was very angry when he learned that Qianlong was going to betroth the Saiya dress to Yongqi, so he had a big fight with Yongqi. Yongqi immediately decided to visit Qianlong for peace of mind in order to understand the ins and outs of the matter. Unexpectedly, knowing that Seya's secret crush was Erkang, Gan Long was unable to resist Seya's insistence and agreed to the marriage.

Yongqi hurried to bring the news to everyone. Wei Zi almost fainted to the ground, and Erkang was also anxious. She insisted that she would not abandon Wei Zi and marry Saiya. In the helpless situation, they finally decided to tell the truth, and the group immediately went to visit Ganlong.

After learning the truth, Gan Long was furious and denounced all those who colluded with Yan Fei and Wei Zi, committing the great crime of deceiving the monarch. In addition, the queen fanned the flames, which made Gan Long really lose his mind. He ignored the tears of Swallow, the call of Wei Zi's family and everyone's entreaties, and gave an order to send Swallow, Wei Zi and Jinsuo to Zongren Mansion.
