Loved this, at first I wasn't quite sure if this was the drama for me when I watched the first episode. It really picked up after the second episode when the storyline turns to the rebirth. While rich vs poor and rebirth themes aren't new or ground breaking, this drama takes these themes and runs with it. It excels in the plotting, acting, character analysis, and storyline development. It's also deeply satisfying to see a down and out underdog who was murdered come back as the grandson of a chaebol family. He plots his way to one up his rebirth family with his intelligence and knowledge of the future. Schemes abound, everyone is vying for the grandfather's favor and the keys to the throne. The dirty inner workings of chaebol families is exposed, the plays for dynastic wealth and power play out like Joseon royal family succession politics. It's appalling, vicious, juicy, and scandalous all at once. I like how the drama develops the relationship between the ML grandson and the grandfather, the grandfather initially views the grandson with curiosity, then suspicion but starts to recognize his talent and his abilities which by far outpaces his other potential heirs. It becomes a chess match between the grandson and grandfather, the suspense is not knowing who will checkmate who.

A round of applause for the actors and actresses of this drama and how engaging they were in their roles, the child actor who plays the grandson with the soul of murdered ML did a wonderful job. It was my first time watching the ML in a drama, he's super popular and he lives up to his acting reputation in this drama.

A very good watch.
