After having watch Jung Jae Hyun carry out his character flawlessly in Justice Partners, I just had to watch something else where he played a similar character. And having watched till Episode 8 as of now and waiting for the upcoming episodes, I could say, he has effortlessly nailed it once again. The other casts are great as well playing their own roles, and although personally I am not a very big fan of 'corporate Kdramas', this series definitely got me hooked as it gives you insight into the real subtle nature of how it is to actually work in a tech company by bringing in all the departments together. Something which most work related and corporate Kdramas just exaggerate most of the time.
Conclusion: You should definitely go for it, if you want to experience some good acting first hand and also looking out to enjoy a good plot overall.
