I loved it that I watched it twice. The cast did great. How can you not rate this drama high? There were playing two different personalities in two different worlds. Do you know how hard that is? Lee Min Ho was awesome in his acting. Everyone did their part. The costumes were beautiful in Corea World. Just imagine if that was possible. If I can go to another world where there is COVID-19 and Trump was not the President, I'd be very happy. My Woo Do Hwan OMG you are a fine young man, cute too. Again, I was born in the wrong era and country. Those eyes are piercing! I didn't know you can be a little comedic. Kim Go Eun, I love her tomboyish acting in this drama. I loved the storyline. If you rated it low I advise you need to go back and rewatch it.
