Do-jun gets into the law school of the most prestigious university at the top of his class as he promised Chairman Jin. The land he received in return provides him enough money to start investing in companies. He goes on a trip to the US with his father and meets Oh Se-hyun, an investment manager.

Soonyang Motors has been Chairman Jin Yang-chul’s long dream. Knowing that, Do-jun fully supports Chairman Jin and earns more trust from him. Soonyang’s longtime rival, Daeyoung bids to acquire Hando Steel, and Chairman Jin learns later that one of his sons was helping Daeyoung behind his back.

The IMF crisis causes Ahjin Motors to file for court receivership. Chairman Jin Yang-chul wants to acquire the company, but Do-jun stops him at all costs because he knows it will bring misery to his family from his previous life. However, things get difficult for Do-jun as Cheongwadae steps in to mediate the acquisition.

Seong-joon joins Soonyang Construction with ulterior motives. Do-jun convinces Se-hyun to acquire Jaea Construction to build a digital media city in Sangam-dong. Soonyang also eyes that area, but they need the new Seoul mayor to give the project to them. Chang-je gets elected as the new mayor of Seoul, but he goes against Chairman Jin and gives the project to Jaea Construction.

Do-jun appears in front of Chairman Jin as the majority shareholder of Miracle Investment. Chairman Jin tells Do-jun that he'll never be able to buy Soonyang with his money. Then he hurries with the succession of the company to his eldest grandson, Seong-joon.

On the day of Seong-joon’s wedding, Chairman Jin announces that he will no longer follow the rule of primogeniture and pass the company down to whoever proves their competence. The siblings of the Jin family eye on each other’s shares, while Do-jun eggs on the siblings to mistrust each other.

The stock price of New Data Technology plummets, and Hwa-young suffers a huge loss. She is soon accused of embezzling company funds. Miracle Investment offers to pay back the money she owes, only to acquire her shares of her department store. Do-jun asks Min-young to investigate Hwa-young’s embezzlement case.

Chairman Jin initiates a plan to establish Soonyang Financial Holding Company to begin his succession process. He puts his trust in his second son, Dong-ki. Dong-ki tries to sabotage Do-jun by spreading a false rumor about Miracle Investment. However, Dong-ki only ends up disappointing Chairman Jin even more.

After Chairman Jin and Do-jun survive the car accident, Chairman Jin secretly looks for the culprit who tried to kill him. The three children of Chairman Jin, who do not know that their father is fine, begin a war of succession on their own.

The board meeting to decide the establishment of Soonyang Financial Holding Company is held, and Chairman Jin Yang-chul shows up, surprising everyone. Do-jun continues to look for the culprit who instigated the murder of Chairman Jin and himself. When he finds out the culprit, he rushes to Jeongsimjae.

Do-jun insists on using an aggressive marketing strategy on Soonyang Motors using the 2002 World Cup results he knows from his previous life. Upon hearing the success of Apollo, Soonyang Motors' new car, Chairman Jin Yang-chul decides to fix his will, which puts everyone in the family in an ordeal.

Do-jun fails to become the CEO of Soonyang Financial Holding Company because of Seong-joon's scheme. Just when he was despondent over the loss, Mr. Lee Hang-jae handed over the will Chairman Jin Yang-chul left for him separately.

Just when Vice-Chairman Jin Young-ki thinks he has won the fight to own Soonyang, Do-jun shares the news that he bought out all of Soonyang Corporation’s shares. The fight to win the management rights of Soonyang continues, and the fight between the Jin brothers becomes dirtier.

After the car accident, Do-jun returns to his old self, Hyun-woo. Hyun-woo needs to clear himself of the charge of embezzling 700 billion won. The Jin family is still in a family feud to win the management rights of Soonyang, and Hyun-woo decides to end the war once and for all.
