I thought "this is another snotty school drama". I haven't read the manga, so I couldn't imagine what would happen next. In the first series, events developed quickly, they were very tricky with memory loss, and in general, twice in a series, I almost died ...
When the Joseon times began, I did not understand anything that was happening at all. But to clarify the picture, she continued to watch and did not regret it. I don’t understand why there is so much negative criticism towards this part, it touched me so much, this time shows all human qualities and attitudes towards people.

In conclusion, I want to say that the drama is very concise, but this is enough to catch the main idea.
