As Washington politics reveals its true face, it casts a long shadow over the relationship between Philip and Bertha, who try to understand each other, but personal emotions and political positions continue to collide, opening emotional rifts between them. The fate of legislation entangled with lobbyists and congressmen influences not only the two but also the lives of those around them, revealing the harsh wall where no one moves by ideals alone. Bertha gradually becomes aware of her political consciousness and social position as a woman, seeking her path not merely as a romantic figure but as an independent subject. Philip supports her but struggles to break free from traditional values, and both find themselves lost and shaken amid the shifting tides of people and politics. This part ultimately shows how characters gradually reveal their true selves and evolve within the tense tug-of-war between idealism and reality, love and responsibility.
