This isn't a new attempt at the "reincarnated kid becomes rich and powerful" plot idea, but it is BY FAR the best executed for the real world genre so far even thinking back with my decades of experience reading manga/manwha. Probably at the very top of my current list of must reads. A story is limited by the experience and wisdom of its author. This kind of story to be told well requires depth of thought and this series has pull it off perfectly. Telling a realistic story of climbing up the ranks of Korean society reveals how much thought the writers have given into this series,even with the advantages of reincarnation and prior knowledge, it is a tough thing to do without pulling some magic spell or techno wizard deus ex copout.

This is even superior to novel, which lacks the family and personal character element in the manwha. A true elevation of the source material.
