Equal parts South Korean and Japanese, Tree of Heaven (or Heaven’s Tree) is a melodramatic show centering on Hana (Park Shin-hye) and Yoon-suh (Lee Wan), two step-siblings who develop a strong bond, although initially with some resistance when Hana's mother remarries Yoon-suh's father. Tackling universal and relatable themes of family, love, and regret on top of examining the inevitable passage of time, this 2019 drama is guaranteed to pull audiences in for its emotionally rich narrative and memorable characters.
