A banquet is held to celebrate Bangwon's coronation, and Won-gyeong and Bangwon rejoice, confirming that they have had a strong love and trust for each other up until this point. However, when Yeong-sil, who secretly raised Bangwon's child during his time as a concubine, appears, the trust between the couple cracks, and this issue escalates into a subject's problem opposing the king's authority.

Yeong-sil, who believed in the king's favor, is rude to Won-gyeong, and Won-gyeong feels greatly insulted. Furthermore, when the woman Bang-won takes again is Chae-ryeong, the woman Won-gyeong trusted, Won-gyeong's emotions finally explode, and he ends up refusing to marry the king... When Lee Seong-gye tries to kill Bang-won with a hammer, Won-gyeong puts aside his feelings of resentment and instinctively steps forward to save Bang-won.

In the process of saving himself, Bang-won feels passionately toward his wife Won-gyeong, who gets hit with a hammer instead. However, he feels a sense of crisis due to the information power of the Min clan, who knew about this fact in advance, and while watching their movements, Won-gyeong detects the movement to restore the former king. If he informs Bang-won of this fact, Won-gyeong and the Min clan will be faced with a dilemma as it will be revealed that they disobeyed the king's order...

Thanks to Won-gyeong's efforts, the movement to restore the former king is completely defeated, but Yeong-sil is unexpectedly involved. Bang-won tries to protect Yeong-sil, the concubine who is implicated in the treason, even breaking his principles. Won-gyeong feels a great shock, betrayal, and jealousy at Bang-won's attitude. Won-gyeong is the head of the palace concubine who has the power to save Yeong-sil. Instead of asking Won-gyeong for a regrettable favor, Bang-won tries to turn the situation around by abandoning Yeong-sil...

In order to be wary of the Min clan who are confident and trusting in the queen's achievements, Bang-won even sets up a wedding ceremony to bring in a concubine. Won-gyeong and Bang-won continue to have extreme conflicts over this issue. Meanwhile, Chae-ryeong, who has sensed the king's loneliness, approaches Bang-won more actively and eventually becomes pregnant.

Finally, when the investigation team causes trouble and Bang-won goes on a campaign, Won-gyeong puts aside her resentment toward Bang-won, realizes her passionate love for him, and mobilizes her intelligence and everything she has to help Bang-won. In her negotiations with Lee Seong-gye, Bang-won promises one thing. He will cut off the vested interests based in Gaegyeong and return to Hanyang. However, the core of those vested interests includes Won-gyeong's maternal family, the Min family.

After returning to Hanyang, Bangwon devoted himself to stabilizing the royal authority and taking care of the people. One day, he received a request for a princess from the Ming Dynasty. Won-gyeong incited his officials to pressure Bangwon, saying that he could not send the princess, and he resolved the issue under his own responsibility. When the Min clan tried to expand their power by trusting the queen, Bangwon tried to break through by declaring that he would abdicate to Crown Prince Yangnyeong…

Under the belief that an unprepared regent could endanger the crown prince's life, Won-gyeong confronts Bang-won and withdraws his intention to abdicate. Meanwhile, after the return of the capital to Hanyang, when the secret real estate speculation of the powerful families hinders state affairs, Bang-won takes special measures. However, Won-gyeong's younger brothers are among the speculators. This puts Won-gyeong in danger...

Bang-won tries to choose the crown princess for political reasons, but Won-gyeong argues that it is right to prioritize qualifications. In the end, Won-gyeong makes the process of choosing the crown princess public, thereby breaking the king's will. Chae-ryeong finds out the whereabouts of Pan-su, who has been Won-gyeong's informant for a long time, and informs Bang-won. Bang-won decides to use this as a means to weaken Won-gyeong's power...

Won-gyeong, who disobeyed the king's orders and left the palace to collect Pan-su's body, finds out that some of the king's relatives have been embezzling the grain and wealth the king had given to the people. He tries to tell Bang-won about this, but he is caught in an unexpected plot and not only does he lose the deposed queen, but his life is also threatened... With the help of the people, Won-gyeong returns to Hanyang and tells Bang-won all of the facts... This incident serves as an opportunity for Bang-won to recall that Won-gyeong had the same dream as him.

Apart from his love for Won-gyeong, Bang-won ordered the death of the queen's younger siblings who were already political obstacles. Won-gyeong, although feeling bloody, tries to understand and accept Bang-won, the king of Joseon, rather than his personal feelings. However, he can never treat Bang-won with the same feelings as before. As Prince Seongnyeong dies together, the two regain their trust as a couple before becoming kings... The last task for them is to replace the crown prince.

Bangwon, who believes that Crown Prince Yangnyeong's qualifications are lacking but can be improved upon, eventually decides to depose Yangnyeong, accepting Won-gyeong's advice that a king who lacks qualifications should be replaced because he is endangering the people. Won-gyeong makes Chungnyeong reveal his vision to his father directly, providing the basis for Bangwon to decide on Chungnyeong as the crown prince... As soon as he ascends the throne, Chungnyeong establishes the foundation for the great Joseon Dynasty that his mother, Queen Wongyeong, had dreamed of so much and makes it blossom.
