FromStrangertoThe Silent Sea, there are plenty of mind-blowing shows that will satisfy viewers on Netflix.

The strange case of the prosecutor without empathy seems to work in his favor; he’s able to understand and digest facts from a more objective and logical side — but is that actually good?

1’Flower of Evil' (2020)
Created by Yoo Jung-hee
Flower of Evilis one of those dramas with such shocking twists that, even if they are expected, they’re still surprising. The story shows an ambitious and clever detective who seemingly has a perfect home life. However, when she starts uncovering new clues from a series of similar murders, she realizes her husband might be more than just a perfect partner.
This suspenseful thrillercan get rather soapy at moments (many K-dramas are at fault for that) but it still manages to deliver an excellent and exciting story. The actor starring as the mysterious husband isLee Joon-gi, who’s widely known as the K-drama prince. His unusual features and subdued but strong acting make his character more creepy and hard to trust.
