Off, Janhae, Louis and especially Mond did an impeccable job with the acting. Mond is a brilliant actor. He really made me loose my mind on his character Sun. The story has few plot holes. I felt like if it was longer with at least 4 more episodes it could have developed well. But it was enjoyable nonetheless. The teaching about value of life was great. It truly shows how the unequal society tricks people based on money. How the rich gets richer and poor gets poorer. The suspense were quite good. Could have definitely been better.
