PSJ was the reason for the success of this drama. You could put a bunch of actors in a room, but no one would have been able to portray his character (Park Saeroyi) like PSJ did himself. This drama was released at a time when Crash Landing on You (CLOY) was becoming one of the highest-rated shows of all times, and whilst this didn't quite compare to CLOY, it did however peak my interest in other ways. For example, the supporting cast involved characters from all different walks of life and is a good affirmation of that saying: "never judge a book by its cover". It highlighted discrimination, gender issues, corporate power/greed, and perserverance very well. There were some scenes which were a bit lacking and the chemistry b/w the lead actors could have been stronger, but overall this drama was well written and directed.

Storyline -- started off great but then overly exaggerated towards the end with unncessary back and forth revenge acts, and in particular, Jo Yi-seo's character who was just annoying, irritating and difficult to watch.

Acting -- great execution and compelling performances by Park Seo-joon in his portrayal as Park Saeroyi, and from Yoo Jae-myung who played Jang Dae-hee (CEO of Jangga Pub).

Characters -- I loved that each character came from all different walks of life and was determined to put up a fight regardless of societal standards and values.

OST -- wasn't that big of a fan of the (pop rock) OST to be honest but maybe just a few song selections here and there.
