Reborn Rookie

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 Taeha'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.

Determined to stand by Bang-geul, Seon-hee declares war on Jae-gyeong and the family, pledging to support her with all her might. Jae-gyeong figures out that Bang-geul and Jun-hyeon are behind Smile Investment. Meanwhile, Chairman Na meets Jae-gyeong and suggests getting rid of Bang-geul for her.

After successfully getting rid of Jae-seong, Jae-gyeong sets Managing Director Lee up and accuses him of trying to take over Choiseong. She calls an emergency board meeting and makes Bang-geul and Jun-hyeon fire 20 percent of the staff. In the meantime, she also makes a secret deal with Chairman Na.

After Chairman Kang’s death, Jae-gyeong openly moves to take over Choiseong Group. She also frames Seon-hee and Bang-geul for Chairman Kang’s alleged creation of slush funds. Determined to take Jae-gyeong down, Yong-ho pretends to betray Bang-geul and joins Jae-gyeong’s side.

Jae-gyeong finds herself on the verge of losing the Daesan Hydrogen Complex to Chairman Na under highly unfavourable terms. Realising that Jae-gyeong is being blackmailed by Chairman Na, Yong-ho pretends to join forces with Chairman Na and ultimately discovers that Jae-gyeong was not the one who killed him. Meanwhile, Bang-geul learns that Yong-ho has sided with Taeha and begins following him to uncover the truth.

Bang-geul finds out who actually killed her dad and swears to take revenge on them. Yong-ho gives the CCTV footage from the hospital to Jae-gyeong, and she uses it to blackmail Chairman Na. Eun-se flies to Singapore to get Chairman Na’s slush fund, but unexpected news hits her while she’s there.

Yong-ho finally wakes up in his body and saves Jun-hyeon, who was in danger because of Chairman Na. Yong-ho asks Jae-gyeong to make things right with him, but she refuses. Jae-seong turns himself in and reveals everything he did with Jae-gyeong.
