One thing I liked the most was that even though there was a huge suspense element in the kdrama, they didn't make the suspense the whole plot of the drama. It was just something going on in the background, and despite the murder mystery and death, it had a very cute rom-com theme. I heard that this kdrama has the same screenwriter as True Beauty, and throughout the drama, you'll find many similarities in the characters, plot, and Easter eggs, especially between 2nd leads Kim Tae Sung and Han Seo Jun.
