Flower of Evil (악의 꽃) is not a series that you will soon forget after watching it. The 2020 tvN series is a fast-paced psychological thriller that is powered by an exceptional character-driven story. In finding the delicate balance between crime, mystery, family, friendship and romance, Flower of Evil crafts a thoroughly engaging roller coaster of a ride. And its great cast, led by an outstanding performance from Lee Joon Gi, solidifies it as one of 2020's best. (And definitely another series that would've made my Top 10 Korean Dramas of 2020 list.)
