The beginning of Flower of Evil is quite innocent. A joyful family is shown, including metal welder Baek Hee-sung, who owns a shop, his detective wife Cha Ji-won, and their daughter. With parents who are devoted to their daughters, they appear to be the epitome of what a model family looks like. However, when we start to discover that Baek Hee-sung isn’t really Baek Hee-sung, things start to change.
A man pretends to be the perfect partner to his detective wife, disguising a dark past, until she starts looking into a string of killings.

However, Jong Woo chooses to endure it for a period of six months in order to accumulate sufficient funds to relocate. But as strange things start happening in the flat, Jong Woo starts to worry about the people living there.

5. Vagabond (2019)
For fans of K-dramas, Vagabond is among the greatest thriller K-dramas. Furthermore, the series features the comeback collaboration of Suzy Bae and Lee Seung Gi, making it a must-watch. Thriller action-packed and full of unexpected scenes, Vagabond will leave you stunned with its twists and turns. You’ll be amazed at how Cha Dal Geon handled all of his close calls with death in order to bring his nephew’s death to justice.
Vagabond falters at the last hurdle, leaving several plot strands unsolved and leaving a terrible aftertaste for anyone who has grown invested in this thriller Korean drama.

Vagabond is definitely worth checking out if it gets a second-season renewal, but even while it’s an enjoyable journey, it falls short where it matters most, making it fall short of greatness and into mediocrity.
