In Princess New Zhu Huan, did Swallow and Yongqi get married? Was it tied in the palace?

There should be no knot. Because there is only Wei Zierkang's wedding scene in the film, but there is no Yan Yong. However, the finale revealed. Swallow and Ban, Yue and He wandered among the people, while Yongqi gave birth to a son with Xinrong under the pressure of the emperor and Princess Chongqing. Two years later, Yongqi finally went out of the palace and found the swallow. But they are not married.
