The story begins with Yulika, a Baron's daughter and the second wife of Anton, a son of the Earl Garland, enjoying a rare lunch with her husband. Their marriage, a political arrangement three years prior, has been amicable, and Yulika cares for Anton's six-year-old son, Noah, from his first marriage. To her shock, Anton abruptly asks for a divorce. Yulika is devastated and confused, as she believed their relationship was good, despite Anton's recent long absences due to his demanding role as Captain of the Royal Guard. She questions if she has failed him in some way, particularly noting her plain appearance and the fact that she hasn't conceived a child in their three years of marriage, a common expectation for noblewomen. Anton insists she is not at fault, but admits he wants to "live freely" at twenty-six, implying a desire for a different life. He asks her to pack her belongings within the month.
Distraught, Yulika confides in Anna, her loyal maid who accompanied her from her family home. Anna, who is close to Yulika and has some familiarity with Anton's household through her late husband, reassures Yulika that Anton is not the type to be unfaithful and that she has noticed no suspicious signs. Yulika feels a sense of abandonment and sadness, reflecting on her marriage and her role as Noah's stepmother.
The next morning, Yulika has breakfast with Noah. He expresses disappointment that his father, Anton, left for the palace again without seeing him. Yulika understands that Noah's father avoids him due to painful memories of his deceased first wife, who died shortly after Noah's birth. Despite this, Anton has entrusted Noah's care to Yulika. Noah excitedly plans a picnic in the forest, and Yulika, though troubled by her impending divorce and the thought of leaving Noah, agrees to join him. She recalls her own childhood spent playing in the woods behind her family's estate, a stark contrast to her current situation.
During the picnic in the Garland family's forest, Noah spots a treehouse. To Yulika's surprise, they encounter a young man named Fee, who claims to have built the treehouse in three days and lives there with the General's permission. Fee recognizes Yulika as "Yuri" from his childhood. He reveals he is a subordinate of Yulika's father-in-law, General Garland, and has been living on the Garland estate. Yulika is touched by the reunion with her childhood friend and finds comfort in his presence. Fee notes how much Yulika has grown and observes that she seems happier with him than with her husband, a comment that makes Yulika reflect on her strained relationship with Anton.
Fee suggests Noah visit his grandfather, General Garland, who has been eager to see him. Fee uses a trained crow, "Negro," to deliver a message to the General's estate, demonstrating a unique ability to communicate with the bird. Yulika, feeling a sense of courage from Fee's support, decides to take Noah to visit his grandfather. She confides in Fee about Anton's request for a divorce and her worry about how to tell Noah. Fee offers his unwavering support and a place to go if she needs anything.
Yulika, Noah, and their retinue then proceed to General Garland's estate. The General, Dennis, is overjoyed to see Noah and warmly welcomes Yulika, acknowledging that he knows about Anton's request for a divorce. He mentions Anton's stubbornness, inherited from his mother. Yulika is impressed by the General's beautiful, flower-filled estate and is greeted by his wife, Margot, a strikingly beautiful woman who is significantly younger than the General. Yulika learns that Margot and the General began their relationship while Anton's mother was ill, a fact that contributed to Anton's estrangement from his father.
