The Story So Far

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.

Following the accident, a fierce succession battle erupts over the vacant chairman position, with three of his children — youngest daughter Kang Bang Geul, eldest daughter Kang Jae Kyung, and eldest son Kang Jae Sung — each vying for control.

Now, the show has unveiled the key allies standing behind each power player — and every single one of them looks fascinating.

The Supporting Players — Who’s Backing Whom

Park Bong Gi — Lee Sung Wook The manager of Choi Sung Trading’s Materials Team 2, Park Bong Gi was once regarded as a star employee in the audit department — until he was demoted after uncovering corruption within the Choi Sung family. He becomes an ally to interns Hwang Jun Hyun and Kang Bang Geul, and begins rediscovering his hidden talents as he teams up with them. A fallen hero ready for redemption — already one of the most compelling characters in the lineup.

Lee Sang Jae — Kim Jong Tae The loyal right-hand man of Chairman Kang Yong Ho and an executive director at Choi Sung Group’s strategic planning headquarters. Having stayed by the chairman’s side for years, Lee Sang Jae closely monitors those seeking to take over the company — but is thrown into confusion when Hwang Jun Hyun suddenly claims, “I am Kang Yong Ho.” That moment of disbelief alone is worth watching for.

Na Eun Se — Lee Seo An The eldest daughter-in-law of the Choi Sung family and the heiress of Tae Ha Group. As the strategic “kingmaker” behind Kang Jae Sung — whom she married in an arranged marriage — she does everything possible to help her husband avoid losing the succession battle against his twin sister Kang Jae Kyung. Cold, calculated, and dangerous.

Min Seok Do — Kwon Hae Sung A neurosurgeon and the husband of Kang Jae Kyung. Determined to support his wife, who is willing to do anything to seize control of Choi Sung Group, Min Seok Do resolves to stand by her side no matter what. A devotion that could either be his greatest strength — or his fatal flaw.
