This show is the continuation of season 1, Season 2 is quite darker and painful compared to the first season.
The story is quite good in terms that it actually depicts the reality of struggle for power and love in palace, as every person is just a puppet or manipulated by the hand of others or their own desires. Therefore, it's not necessary that the things will end according to u.
This show could have been a lot more better compared to what they have done, a good plot got ruined becoz of bad execution and in the end so many matters remains unanswered and confusing. Just like the character of 4th prince is quite complex they should have invested time in letting the viewers know his true colors and ambitions, also they should have shown how the crown prince is working hard to become compatible for his lady love and may other matters which i have already mentioned in the comment section.
