This manhwa is very in-tune with the machiavellian nature of industry and the inherent politics every interaction amongst the rich consists of. Obviously though as the story is of a wronged employee who was completely loyal and yet discarded by the family without a remorse, it is not the most creative one out there. A lot of is pretty predictable with the chaebol being disappointed by all his sons for being talentless second generation heirs and extremely proud of the MC for being a prodigy (not exactly earned rightfully since he has the knowledge of the future, but oh well.) We also have the lack ofdepth most characters have as they refuse to question MC and are charmed by his skills. There is however the supporting character of the uncle who gives him a slap on the wrist once in a while.
In any case, while it may seem otherwise, this is absolutely worth a read. I always have a smile on my face when an update comes because critical analysis aside, the beauty of this manhwa lies in the interactions between characters and the business acumen the characters apply during all sorts of financial events even while the MC technically knows the future (aka the small details.)
