It starts off as a transmigration story, a modern girl gets thrown out to ancient realm for some reason. We see her trying to figure out her newlywed cold/distant husband as well as the results of the shock of everybody nearby with her new spirit and personality. Yes, cute and light. Then we get a twist in the trope as the girl and her spouse switch bodies/souls and learn to like and support one another -again, pure fun as M/FL are really good embodying the opposite gender roles. Then we start wondering about the transmigration as we see the leads in modern times in not so good situation: she lost her memory of their happy marriage, and the spouse suffers by her bedside. And then the usual fight for the throne with the Crown Prince, as well as avenging dead mother plot of ML, while FL is still trying to figure out how to get back to her modern reality and life. And then we wonder if perhaps these two lovers are shown in two lifetimes as twin flames: on and off again...? And then we find out that the transmigration is really the modern wife's subconscious attempt at getting at the truth about her "happy marriage". I loved the ending in both story lines - not really an open ending or a cliffhanger, but a nudge toward what might happen with these two in the next reincarnation. The acting was good, OST well done, editing and production for this 12 minute mini series commendable.
