The plot of this time travel drama seems to be stuck in a repetitive cycle, with a predictable storyline and a disappointing ending. However, there are a few positive aspects to the show, such as the dual identities of the male lead and the inclusion of an AI-powered watch and the good-looking male actors. The first part of the drama may have been a bit redundant, but the fact that each episode is only 10 minutes long makes it easy to overlook this issue.

The show takes a dark turn when the female lead is killed off so that she can return to modern times, leaving behind a heartbroken male lead. However, the plot twist that follows is interesting, as the female lead wakes up to find that her beloved's twin resides in the person of her professor.

Although the female lead is not particularly captivating, he is still a better character than the female lead in another time travel drama called "Different Princess". If you're looking for a show to take your mind off things, this might be a good option. While the first two-thirds of the show are entertaining, the last part could be improved.

The OST deserves all the praise! I'm almost certain that it's the same composer as "Love like the Galaxy" - a piece of music that I absolutely loved.
