Good fantasy drama to watch

Hi everyone, I have registered on mdl to say thank you for this drama
I didn't have much expectations, and there were some moments which I fast-forwarded, but in general it is really good one!
It started as a light comedy story with childish female lead (as usual...), but I watched the trailer before and knew that it will turn into a drama. It's fine. I like difficult stories with logical ending.
Acting and actors are superb. I don't know them, but I would watch new dramas with them.
Thank you again!
