I don't get it why some people didn't like or gets confuse with this drama, I mean this k-drama is actually pretty interesting and cool. The parallel universe concept of it got me hooked instantly and the actors/actresses are very good at portraying their character roles. Some are offended because it is not historically accurate, but that's the point of fiction right? It is supposed to not be based on reality instead it is based on imagination and creativity. This drama is one of the reason why I'm surviving from the devastating boredom that the quarantine has caused. Ya'll should watch it and I promise you will enjoy it.
