Rookie Employee Chairman Kang

Chairman Kang Yong-ho announces that he’ll step down and choose his successor. His twins, Kang Jae-gyeong and Kang Jae-seong, instantly switch into competition mode. Jun-hyeon finally signs with Choiseong FC. On the way to celebrate it with his grandma, he gets hit by a car. After finding out he can’t continue his career, he focuses on the hit-and-run driver of the accident.

After hearing about the accident Yong-ho was in, Bang-geul rushes to the hospital and runs into Yong-ho in Jun-hyeon’s body. Yong-ho is accused of being the hit-and-run driver and faces a fierce public backlash, while Jae-gyeong seizes the opportunity to force him out of the chairman position for good. Jun-hyeon joins Choiseong Group as an intern.

Determined to help Bang-geul, Yong-ho sets out in Jun-hyeon's body to uncover the twins' hidden stash of illicit funds. As the twins compete for the position of the next Chairman, they quietly carry out their own schemes behind the scenes. Jun-hyeon's grandmother sets off for Seoul to find her grandson. When Bang-geul learns of her disappearance by chance, she joins the search and helps track her down.

The disappearance of Managing Director Song becomes the subject of a police investigation, putting Jae-seong in a difficult position. Yong-ho realises that Jae-seong intends to sabotage the port project for Tae-ha's benefit, his father-in-law's company. Yong-ho sides with Jae-gyeong and shares everything he knows, deepening the twins' mistrust of one another.

Chairman Na insists that GF Solution must be acquired and assures Jae Seong that Taeha will back the deal financially if needed. Yong Ho manipulates both Jae Gyeong and Jae Seong into driving up the acquisition price to an absurd level. Meanwhile, Yong Ho reveals to Sang Jae that he is Yong Ho, now living inside Jun Hyeon's body.

Yong Ho, Bang Geul, and Bong Gi travel to Yulivia to steal the mining project Taeha has been working on. They figure out Chairman Na’s scheme against Yulivia’s government. Seon Hee finds out that Jae Gyeong and her husband have been sedating Yong Ho to keep him from waking up. After learning about this, Yong Ho and Bang Geul decide to reveal themselves to the board of directors.
