| Reborn Rookie Relationship Chart Explained: Who’s Who in JTBC’s New Fantasy Office Drama and Which Family Member Is Most Likely to Cause Chaos? (Credits: jTBC) |
JTBC’s upcoming fantasy business drama Reborn Rookie (신입사원 강회장) arrives with a premise that sounds ridiculous on paper and surprisingly addictive in practice. One moment, legendary conglomerate chairman Kang Yong Ho is running one of Korea’s biggest companies. The next, he wakes up inside the body of a twenty-something football player and suddenly finds himself back at the bottom of the corporate ladder. If that sounds like the sort of story that could spiral into complete workplace madness, that is exactly the point.
Set against the backdrop of the powerful Choi Seong Group, Reborn Rookie combines mystery, business politics, family rivalries, comedy and fantasy into one ambitious package. While the body-swap element grabs attention first, the real story appears to revolve around inheritance battles, hidden agendas and a wealthy family that seems permanently one awkward dinner away from total collapse.
At the centre of everything is Lee Jun Young, who takes on the dual challenge of portraying both Hwang Jun Hyeon, a young football player, and the spirit of chairman Kang Yong Ho after the life-changing accident that alters both of their destinies.
This means viewers will essentially be watching a veteran corporate mastermind trapped inside a young man's body while trying not to expose his true identity.
The concept alone creates endless opportunities for comedy, especially when a man who once owned the company suddenly has to survive as an ordinary employee following orders from people he used to command.
The original Kang Yong Ho, portrayed by Son Hyun Joo, remains one of the drama's most important figures despite the body-switch premise. Before the accident, he was known as the powerful chairman of Choi Seong Group, a man whose decisions shaped an entire corporate empire.
Even after his soul leaves his original body, his influence continues to loom over every character connected to the family business. In many ways, the entire drama revolves around the question of what happens when the most powerful person in the room suddenly disappears.
Then there is Kang Bang Geul, played by Lee Joo Myung, perhaps the most intriguing wildcard in the entire cast. Described as a hidden child connected to the chaebol family, she enters the story carrying ambition and secrets of her own.
Early character descriptions suggest she could become either Kang Yong Ho's greatest ally or the person who creates even more complications. In a drama built around trust issues, hidden family members rarely arrive without causing trouble.

| Reborn Rookie Character Map Explained: From Chairman Kang Yong Ho to Hidden Heirs, Here’s How Everyone Is Connected |
The inheritance battle becomes even messier through Kang Jae Gyeong, portrayed by Jeon Hye Jin, and Kang Jae Seong, played by Jin Goo. Both are children of Kang Yong Ho and both appear deeply connected to the succession struggle surrounding Choi Seong Group.
Jae Gyeong looks positioned as a strong and influential figure within the family, while Jae Seong carries layers of insecurity and ambition that could easily push him toward risky decisions. If there is one rule in chaebol dramas, it is that family meetings are rarely about family.
The extended family tree only adds more fuel to the fire. Cho Sun Hui, played by Yun Yu Sun, is Kang Yong Ho's second wife and naturally occupies a sensitive position within the household hierarchy.
Her eldest daughter-in-law, Na Eun Se, portrayed by Lee Seo An, connects the family to another powerful business dynasty through her father Na Byeong Mo, chairman of Taeha Group. Suddenly this is not just one wealthy family arguing over power; it is multiple influential families with competing interests.
Away from the family mansion, the office environment introduces another key player. Park Bong Gi, portrayed by Lee Sung Wook, serves as Materials Team 2 manager and is likely to become one of the first people interacting with the "new employee" version of Kang Yong Ho.
Watching a company manager unknowingly supervise the man who used to run the entire corporation sounds like the kind of irony this drama intends to exploit at every opportunity.
Other important supporting characters include Lee Sang Jae, a senior executive within Choi Seong Group, Min Seok Do, husband of Kang Jae Gyeong, along with their son Min Il Jun, while Kang I Jun represents the next generation through Kang Jae Seong's family line.
Even before the first episode airs, it is clear that every branch of the family tree has something to gain or lose depending on who ultimately controls the company.
One reason the drama has generated significant attention is the involvement of Kim Soon Ok as creator. While she is not serving as the sole screenwriter, her name immediately raises expectations because viewers associate her projects with explosive family conflicts, shocking twists and characters who rarely choose the sensible option when chaos is available.
The screenplay comes from Hyun Ji Min, while direction is handled by Go Hye Jin, creating a creative team that appears ready to lean fully into the drama's larger-than-life premise.
As for what audiences should expect, the fantasy element may be the hook, but the corporate succession battle appears to be the main event. The biggest mystery is not whether Kang Yong Ho can adapt to life as a rookie employee.
It is whether he can stop his family from tearing apart the empire he spent years building. Every character seems to have their own agenda, and every relationship comes with enough tension to fuel several episodes.
Online reactions have already been mixed in the most entertaining way possible. Some viewers are excited by the unusual combination of office comedy and chaebol intrigue, calling it one of the more original premises arriving this year.
Others remain cautiously optimistic, wondering whether the drama can balance fantasy, mystery and business politics without becoming overly complicated. Meanwhile, fans of Lee Jun Young are particularly eager to see how he handles the challenge of portraying a young athlete carrying the personality of a veteran chairman.
Many have joked that the real challenge is not acting like a chairman, but acting like a chairman trying desperately not to look like a chairman.
With its body-swap premise, corporate power struggles, complicated family relationships and a cast packed with experienced performers, Reborn Rookie looks determined to turn a standard office drama into something far messier and far more entertaining.
The real question heading into the premiere is simple: who actually wants control of Choi Seong Group, and who is hiding their true intentions? Is Kang Bang Geul the secret game-changer, can Kang Yong Ho reclaim control from the shadows, or is someone else about to steal the spotlight entirely?
