I highly disagree with comments that this drama is boring. I must say that it's one of the best I've seen. The plot is overall incredibly good written, with an ending you wouldn't expect in the first episodes. It does play on your emotions, which surprised me, because after Moon Lovers which is my best and My Dearest, I wouldn't expect any other drama to put me that high with my feelings. The enemies-to-lovers was not just another dull story, but really deep, probably mostly because of the reincarnation theme. Highly recommend to watch.
