First things first.
I enjoyed watching this drama. Yes, it was not almost a perfect, but it was very enjoyable.

This drama is perfect for those who wanted to enjoy a good mystery series At only four episodes long, this doesn't require viewer to invest 16 hours of their time. A perfect series to binge-watch in the weekend.

The series started off with a countryside couple, couple winning a big lottery. What follows is a series of catastrophic events that ends up consuming the lives of the villagers, the friends, and the families. It's the story of betrayal, friendship and revenge. It explores the greed of human and what we are capable of doing.

The writing is very good. The writer managed to wrap up this good and the ending was just excellent. The only reason I didn't give it a perfect star because I still didn't know what happened to Joo-hyub. But that thing set aside, it was intelligently written.

Park Ho San was brilliant throughout the four episodes. I've been his fan since Prison Playbook days and was expecting good acting from him in this mystery series. He clearly didn't disappoint me. I think he might've just won himself Best Actor in a Short Drama award at MBC Awards this year. He was bloody brilliant.
The rest of the cast were good too, particularly the actor who played the role of In-Sung.

BGM was awesome.
