First, I want to comment on Moon Ji Yong's performance in this, 10/10. This man has rangeeeee, I've seen him in other works like " The new employee" where he was a dorky sweet guy, but in this I felt so many emotions. His character completely drew me into the story so props to him. The story was interesting and I was engaged the entire time, however I won't spoil the ending, I'll just leave it at this...WHY? Anyways, I watched this series earnestly in one go, I enjoyed it and hated it all at the same time, cried a lot, enjoyed the bits of romance, but really wanted to find whoever wrote this and sit in front of their home until they changed everything. The production of the show was fine, nothing fancy but not bad by any means. I enjoyed the OST for the show a lot it was pleasant at the times it was used. Acting from everyone was good, and from Moon Ji Yong it was exceptional. I'll recommend this show for those who like fantastical star-crossed love stories but with a warning, you will wish you could re-write it.
