Before I start complaining, I want to acknowledge that overall it's a nice drama that can be enjoyed without much frustration. Here goes:

The ML-FL relationship was volatile. She loved ML, but later she wasn't sure. He, on the other hand, loved her after a start-up period and then wholeheartedly. FL didn't want to take it that far. She rejected marriage with ML. For her part, the relationship was intended to be superficial and temporary. The loud lovey-dovey on the part of FL was therefore for the cat, the upright ML, who does not love easily, one could feel sorry for. One could have shouted at him: leave the bride, find something better.

The psychology of the main characters is therefore not very believable, it grew on the crap of the writer-girls. According to the mood of the day and gut feeling.

One could cynically say to the princess: By marrying the culturally challenged Tuo Ba Lie, she has found someone with whom she can spend her whole life until the end. She had refused this with Shen Yan.

Towards the end, however, FL overflows with declarations of love and marriage wishes. There is a lot of catching up to do. Here, their love is reworked, which could not really convince before.
But in the end everything turns out well, for everyone, and there is a nice happy ending, what more could you want.

The main actors, but also the others were good. And Yuan Bing Yan has the most beautiful mouth anyway. That's why it's okay to watch the series. Only: why is Shen Yan a vegetarian? What is wrong with him?
