The personality of the crown prince that was built throughout the entire series was of a wise man, dedicated to Joseon and ready to take on the responsibility. A man destined to be a great king, and he simply abandoned everything for a woman, as if it were nothing?

The most serious issue is the fact that his brother took the throne, a spoiled boy with no intelligence. I am giving a high rating because the series overall is a wonderful political plot, and because of Suho's performance, but I will pretend the last 10 minutes didn't exist.
