She Was Hidden, Dismissed, and Underestimated — Reborn Rookie’s Lee Ju Myoung Is About to Prove Everyone Wrong

A secret daughter. A disguised identity. A goal to rise from the very bottom of her own father’s company. JTBC’s Reborn Rookie just introduced one of the most quietly compelling characters of 2026 — and she mixes a mean somaek.

What Is Reborn Rookie?

Reborn Rookie follows Kang Yong Ho (Son Hyun Joo), the powerful chairman of the leading conglomerate Choi Sung Group, who is revered as a business genius. After an accident, he unexpectedly finds himself living a second life when his soul swaps into the youthful body of a soccer player named Hwang Jun Hyun (Lee Jun Young), forcing him to start over as a rookie employee at his own company. soompi

It’s a classic body swap premise with a corporate twist — and now we know the character who might steal the whole show.

Reborn Rookie: Overview

Meet Kang Bang Geul — The Hidden Daughter With a Secret Plan

Lee Ju Myoung plays Kang Bang Geul, the youngest daughter of Choi Sung Group Chairman Kang Yong Ho, who has been kept hidden from the public.

Her backstory is equal parts heartbreaking and fiercely motivating. Fifteen years ago, her father sent her abroad for forced studies out of concern for the position of his children by his legal wife. Since then, she has pretended to be a troublemaker who only goes out to have fun — while secretly holding onto the ambition of one day proving her abilities to Kang Yong Ho, who once dismissed her.

Rather than confront him directly, she plays the long game. Kang Bang Geul quietly ends her studies overseas without telling anyone and joins Choi Sung Group as a new employee under a new identity, Casey Kang. Her goal is to prove she can rise from the bottom to the top on her own without any support from the Choi Sung family.

And then life throws her a curveball — before she can fully show her abilities, she learns that Kang Yong Ho has collapsed, leaving her feeling a deep sense of emptiness. Her long-held plan suddenly collides with emotions she wasn’t prepared for. soompi

What the Stills Reveal?

The newly released character images paint a vivid portrait of Bang Geul’s dual nature. At a company dinner that feels like an extension of work, Kang Bang Geul keeps a bright smile and shows strong social skills — her careful attention to mixing somaek suggests she will become a well-liked intern on the team.

But scratch the surface, and there’s so much more underneath. With a hardened expression and a cold gaze, she shows both determination and a subtle sense of sadness — teasing what she truly hopes to gain at Choi Sung Group and what her hidden intentions may be.

Cheerful on the outside. Burning with purpose on the inside. This character is going to be magnetic to watch.
