I still haven't found a real answer to why most daily dramas convert their setting into a cyclical run inside a corporation despite their initial premise. Possible theory, it's easier to write while rehashing from its predecessors and to re-use the same materials and assets while building a set. Out of all the possible ridiculous tropes to ensue insanity, the psychiatric hospital trope is the only one I will never tolerate. It's the cheapest and lowliest insult to the medium and to any viewer. Therefore, this drama gets the stamp of shame for incorporating that once and attempting to do it another time later. The final resolution for these characters ended up being disappointing, they forced it to remain relatively soft and tame. Which took away from all of the angst and revenge. Park Ha Na picked up this project after her previous one Apgujeong Midnight Sun (2014) which was pretty good even for her first main role, in comparison, this drama was a significant downgrade.
