Kim Hui Wu, the so-called "good guy," has the aura of a villain, making him hard to relate to. He’s arrogant, obnoxiously confident, and shows almost no emotion — I’m not sure if it's the Botox, but even his smiles feel strained.
He used his friend to send her own father to jail and shamelessly flirted with her, knowing she had feelings for him. It’s completely unrealistic that someone as intelligent and powerful as Jo Tao Soep could be manipulated so easily, right up until the final two episodes.
In his first life, Jo Tao Soep was ruthless and murderous, yet in his second life, he only killed one victim — it doesn’t add up. The acting is strong, but the writing is terrible.
The last few episodes were especially difficult to watch. In reality, no one would challenge someone that powerful, survive it, and then go on to live happily ever after with family and friends. Revenge always comes at a cost — you don’t just dig two graves, you burn everything down along the way.
No wonder the show isn’t very popular in other countries.
