i wonder why this drama has such a low rating and popularity , because i was very satisfiiied with it . it felt original, and unorthodox . the tension between the two leads was insaaane , no pun intended lol since they both had sociopathic tendencies. Also this show gathered so many cool themes like Tech, dating apps, serial killing, psychology , shamanism , loneliness , and all of that was wrapped in a noir , whiskey like decor . Kim Yeon Kwang has been joinin very interesting project lately , and i cant have enough of it .
