Memoirs of a Murderer

Both feature the stories of serial killers
Yurigokoro is show-cased in diary entries, it focuses on female serial killer
Memoirs of a Murder features the book, interviews of a male serial killer
Both have twists and unexpected turns and twisted relationships.

The 2017 version is a Japanese Remake of the Korean Version. Tatsuya Fujiwara is brilliant here as Park Shi Hoo was in the first one.
