Character Arc
Jeong Jae-i is one of the central figures of Jooshin High School's ruling circle, a poised and influential student whose family standing places her near the top of the academy's social pyramid. Composed and image-conscious, she has learned to navigate a world where reputation is currency and every relationship carries strategic weight, and she carries herself with the controlled confidence the elite circle expects of its own.
The arrival of scholarship transfer student Kang Ha disturbs the equilibrium Jae-i has helped maintain, drawing her into the questions he raises about a classmate's death and the secrets the school's powerful families would rather keep buried. As the season unfolds, her loyalties and her sense of where she truly stands are tested, complicating both her place in the hierarchy and her relationships within it.
Jae-i functions as a lens on the show's central tension between privilege and truth, a character who embodies the comforts and constraints of belonging to the top 0.01 percent.
