I watched the whole show in 2 days and let me tell you it's totally worth a shot.
It does have so many parts that can feel dragged but the overall experience of watching it is really good.
Let me break the review down
For starters, the story is well written. Though the plot as a whole is not entirely unique it does have its own charm.
The romance of the main couple is slow and subtle in the beginning but the pacing is done right so it doesn't feel too rushed or too slow.
The ending is also well wrapped.
As for the acting, All the actors did a great job, especially Kwak Dong Yeon.
The Music was good but nothing that stood out to me.
Wouldn't necessarily rewatch the whole show but some episodes.
Overall it's a good show to watch if you like romance with a bit of mystery.
