What is the ending of Princess New Zhu Huan, Swallow and May, and what happened between them?

May didn't marry Xinrong, but in the end Yan Yong got together. On their wedding night, the swallow dreamed of May and Xinrong, but it wasn't. Xinrong threatened Mei that if she was not with him, she would embarrass the swallow in front of the emperor and Lafayette, and even hurt the swallow. May has to spend some time with Xin Rong. Xinrong figured it out. She married a Mongolian, Yan Yong lived together, and Benjamin quietly left.

As a fan of Yan Yong, I think Xinrong is really shameless! However, this is just an act, so I won't hate Xinrong so much.
