Who is the fugitive of Princess New Zhu Huan? Is there ertai and Sunny?

There should be no Ertai, because Ertai and Isaiah were already in love at that time. E Ertai was in Tibet and had married Isaiah. Galeries Lafayette always disagreed with Sonny and Xiao Jian and wanted to show Sonny to others. Swallow is willing to exchange his happiness for his brother's happiness because of May (I can't remember clearly), but it's all right in the end. ==
