Executive Summary
Watch it. It’s really pretty good and has a very nice ending. I don’t agree with the very low ratings, although it is not a “great” series. Fantasy is not my thing, but I did enjoy this series.

There is a mystery running throughout the series and they don’t reveal what is really up until near the end, and it was a bit of a surprise. So they did a good job.

The cast is great, especially the main couple (Nana and Jang Dong-Yoon) and the FL’s roommate (Gong Min-Jung). The main couple is pretty dour most of the time, because of their sad past. And that may be why some folks think the main couple lacks chemistry. But what makes the series work, for me, is that the lighter moments are really cute. When the FL is happy she lights up the room and steals the show! I would love to see her in more of a RomCom role where there is more happy and less sad. I think she would absolutely knock it out of the park in such a role. I’ll cross my fingers :-)

(Spoiler Alert)
And super extra points to the writers for giving us quite a few minutes of happiness at the end, and glimpse into the future of the couple after they are able to reunite. We need more of these types of upbeat and more complete endings. Yay!
