A new member of Sung Jin-woo’s family has reportedly been cast.
Rising actress Choi Myung-bin is reportedly joining Netflix’s highly anticipated live-action adaptation of Solo Leveling, where she will play the younger sister of Byeon Woo-seok’s Sung Jin-woo.
According to an exclusive report from OSEN, Choi Myung-bin has been cast as Sung Jin-ah, Jin-woo’s younger sister, adding another important character to the protagonist’s family.
Choi Myung-bin to Play Sung Jin-ah
In Solo Leveling, Choi Myung-bin will portray Sung Jin-ah, the younger sister of Sung Jin-woo.
Her character is Jin-woo’s only sibling and will be part of the protagonist’s life outside the dangerous world of Hunters and monsters.
The casting also means viewers will get to see Byeon Woo-seok and Choi Myung-bin portray siblings on screen, creating a different dynamic from the actor’s usual romance roles.
From the Weakest Hunter to Humanity’s Strongest
The live-action Solo Leveling follows Sung Jin-woo, an E-Rank Hunter considered one of the weakest Hunters in a world where mysterious Gates connect Earth to dangerous monster-filled realms.
After finding himself facing a life-or-death situation, Jin-woo undergoes a mysterious awakening that allows him to level up in a way no other Hunter can.
His journey eventually transforms him from the weakest Hunter into a powerful figure capable of protecting humanity.
Sung Jin-ah's role provides an important connection to Jin-woo's life before and beyond his transformation into a Hunter.
