U will know if u watch it. It is pretty similar. The divorce plot. The successful girl and not so successful guy plot with Nita Xia (my fav couple).

They both have the 'married to a person I don't love' trope. The second lead couple is similar to the main couple in my heart. Both princesses are titled 'naughty' both male leads are like the playboy nice type. Both are the first sons to the emperor but not the succesor.
