The only good thing about this drama is the acting of the actors and their visuals, the plot is very messy and not recommended to watch because it'll only waste ur time. The connection between the real life and historical time is unanswered and the plot twist is a pain in the head. It also felt rushed because the explanation on why FL is transported to the past is unanswered and why ML also has the vision of the past and also in the Hospital. Idk who is really sick between them and what's the reason of their separation in real world. I think that it should have episodes focusing on their real life or present time because as I said, a lot of things are left unanswered and the plot is quite messy.
