The Chairman in an Intern's Body: What JTBC's Reborn Rookie Reveals About Korean Workplace Fantasy

A 72-year-old chaebol chairman wakes up in the body of a 27-year-old intern and immediately challenges his superior to a drinking contest. It sounds like a premise from 2015 — because, structurally, it is.

JTBC's upcoming 12-episode office fantasy Reborn Rookie premieres May 30 in the Saturday-Sunday primetime slot. Based on a webnovel, it's directed by Go Hye-jin (who helmed My Youth) and written by Hyun Ji-min (of Pandora: Beneath the Paradise). The setup: the CEO of Choiseong Group, Chairman Kang Yong-ho (Sohn Hyun-joo), falls into a coma and wakes up inhabiting the body of new intern Hwang Joon-hyun (Lee Jun-young). His heirs — bickering twins Kang Jae-sung (Jin Gu) and Kang Jae-kyung (Jeon Hye-jin), plus youngest daughter Kang Bang-geul (Lee Joo-myung) — circle the vacant throne, unaware that the disruptive intern is their father.

The Body-Swap Formula and Why It Keeps Coming Back

Body-swap and identity-displacement plots are a recurring fixture in K-drama, from Kill Me Heal Me (2015) through various romantic fantasy permutations since. The format's persistence isn't a sign of creative exhaustion so much as a reliable delivery mechanism for something Korean workplace dramas have long needed: a socially acceptable way to mock the hierarchy.

When a chairman occupies an intern's body, every act of arrogance becomes comedy. Joon-hyun steals a senior's microphone, challenges a superior to a drinking match, openly taunts colleagues to guess his real identity — all behaviors that would read as insufferable from an actual intern, but land as farce because the audience holds the information asymmetry. That gap between what the character knows and what everyone around him doesn't is the engine of this genre's comedy.

The timing matters. Korean workplace content has shifted noticeably since the grounded realism of Misaeng (2014). Where that drama mapped the quiet brutality of corporate hierarchy with documentary precision, the mid-2020s trend runs toward fantasy as a release valve. My Liberation Notes (2022) offered escape through rural detachment; Reborn Rookie offers it through literal power displacement. The premise doesn't critique the hierarchy — it inverts it for laughs, which is a different, and arguably more comfortable, proposition.

Lee Jun-young and the Idol-to-Actor Pipeline

Casting Lee Jun-young — a former member of idol group Uni.T — as the lead of a major JTBC primetime slot is a calculated bet with a legible logic. Since IU's breakout in Hotel Del Luna (2019), the idol-to-lead-actor transition has become a recognized industry pathway. Fandoms generate early buzz; drama quality determines whether that buzz sustains.

What makes this casting architecturally clever is the built-in safety net: Sohn Hyun-joo, a veteran actor with decades of dramatic weight, plays the same character. The two performers are, by design, the same person. Any scene where Lee Jun-young's range is tested can be counterbalanced by the emotional register Sohn Hyun-joo establishes in parallel. It's a structure that protects the production's credibility while giving the younger lead room to grow into the role.

The supporting cast reinforces this logic. Lee Joo-myung, who played the lead in Go Hye-jin's previous work My Youth, returns as the youngest daughter — a director-actor trust relationship that tends to produce more grounded performances. Jin Gu and Jeon Hye-jin bring substantial drama résumés to the sibling rivalry storyline, giving the succession plot an anchor independent of the body-swap comedy.

Where JTBC's Saturday-Sunday Slot Stands Now

JTBC's weekend primetime block once defined prestige Korean television — My Ahjussi, SKY Castle, Itaewon Class all aired here. Between 2023 and 2025, JTBC shifted toward co-productions with Netflix, which redistributed some of its marquee energy toward global streaming rather than domestic broadcast ratings.

Reborn Rookie is a webnovel adaptation positioned as a lighter, broadly accessible fantasy comedy — the kind of show designed for weekend viewing without demanding sustained emotional investment. Whether it receives a simultaneous Netflix release hasn't been confirmed, which itself is a data point: not every JTBC title now defaults to global OTT co-distribution, suggesting the broadcaster is still calibrating which content belongs where.

On the competitive landscape: tvN continues to anchor its lineup with genre-driven productions, while MBC and KBS lean toward melodrama and family dramas. JTBC's choice of a workplace fantasy for its Saturday-Sunday slot reads as a bid for the 20-to-40 employed demographic — viewers who want their office frustrations processed through something that doesn't require them to feel bad about it.

Webnovel adaptations have expanded rapidly in Korean drama production since 2022, offering pre-built fanbases that cushion early ratings risk. The tradeoff is a familiar one: source material fans arrive with fixed expectations, and the gap between those expectations and what a 12-episode adaptation can deliver has generated notable backlash in several recent cases.
