Y·N and adoptive parents

Y/N's relationship with her adoptive parents is the first and most formative structure of abandonment in the story. Her parents neglect her, take away the money she earns through hard work, treat her presence as an interruption, and ultimately send her away; even after her adoptive mother is found dying, the mother still addresses Y/N directly and asks her to close her eyes, suggesting that the family bond has never been simple enough to disappear into mere cruelty.

Neglect, Labor, and Control

Y/N grows up as an only child in a household where her mother and father pay little attention to her. She works hard to obtain things for herself, but her parents confiscate all her money. Their repeated arguments about money explain the material basis of the household's hostility: Y/N is not merely ignored, but treated within an exploitative domestic economy in which her labor is taken while her needs remain unrecognized.

The morning departure scene makes that hierarchy explicit. Y/N hears her parents arguing downstairs, understands that money is again the subject, and goes down to them. Her father dismisses her by saying that he and her mother are discussing something important, while her mother orders her to return to her room. Y/N does not protest; she goes back upstairs and lies on her bed. Her silence is not evidence of security or obedience freely given. It shows how thoroughly the household has trained her to withdraw when the adults define her as an inconvenience.

Expulsion and Abandonment

The parents' control becomes direct expulsion when her mother tells her to gather her belongings and come with her. When Y/N asks why, her mother does not explain the decision, repeating the command instead. The absence of explanation turns the parental relationship into an arbitrary power relation: Y/N is expected to obey without being told what she has done, where she is going, or whether she has any meaningful choice.

Y/N later describes her childhood to Jin as abusive. This retrospective statement gives a name to the pattern that earlier scenes show through money-taking, dismissal, and coercive commands. It also explains why the apparent offer of a new home affects her so strongly. When Jin says that she will find life much better with him and the other residents of Vampire Castle, Y/N immediately objects that she never agreed to stay. The exchange echoes her experience with her parents: one household forces her out, while another initially assumes the right to decide where she belongs.

The Mother's Death and the Birth of a Secret

Despite the abuse, Y/N still feels the pull of her adoptive family. When she hesitates over whether to call her mother, she reminds herself that her parents hate her and questions why she should contact them, yet an impulse leads her to make the call. That decision takes her back to Y/N's Parents' House, where the door is broken open and her mother lies on the floor in a pool of blood.

Y/N sits beside her mother and holds her head in her hands. Her mother manages to direct her toward a book in the desk, but then life leaves her eyes; she has no pulse and does not move or speak again. The scene confirms the physical finality of the mother's death while preserving an emotional contradiction. Y/N's response is not detached relief at the end of an abusive relationship. She breaks down in tears, and the act of holding her dying mother's head reveals an attachment that the household's mistreatment never fully destroyed.

The book becomes the material remainder of the relationship. Its first visible entry is dated 14 April and begins with the account of something strange: a child found lying in a basket after the mother returned from shopping. The diary therefore opens a route from domestic violence and bereavement toward the concealed history of Y/N's origins. The mother cannot explain that history in person, but the desk, the book, and her final words preserve information that may revise what Y/N believes about the family that raised her.

A Pattern Repeated in the Castle

Y/N's parents establish the original model through which later relationships are measured. At home, her earnings are taken; in Vampire Castle, her blood is repeatedly treated as a resource. V asks who is the only blood vessel present, and Jin later makes an explanation about V, Jimin, and Jungkook conditional on receiving Y/N's blood. When Jin drinks from her, Y/N experiences pain and terror, wondering why she trusted him. The language of possession changes, but the underlying danger is recognizable: Y/N's body is again placed under the authority of others who decide what they may take from her.

This repetition makes her eventual choices significant. When JB asks whether she will act, Y/N thinks that saving the others matters more than learning who or what her parents were and points toward the dark bubble. Her decision does not erase the unresolved family secret; it shows that she refuses to let the question of her parentage determine every moral choice. Her adoptive parents gave her neither reliable care nor secure belonging, while her later actions gradually convert the position of an exploited human blood vessel into that of an active decision-maker.

Final Recognition and Ambiguous Meaning

The parental relationship receives its last major image in a later encounter with Y/N's mother. After Y/N asks whether it is good that he is gone, her mother places a hand on Y/N's forehead and says that events were not meant to happen that way before asking Y/N to close her eyes. The gesture is intimate but unsettling. It resembles maternal care, yet it is attached to concealment and an instruction Y/N does not understand.

That final contact prevents the relationship from settling into a single interpretation. The mother is responsible for a history of neglect and abuse, and her household has already abandoned Y/N, but she also leaves behind a diary, recognizes Y/N, touches her forehead, and speaks as though a larger plan has gone wrong. The bond is therefore presented as both wound and clue: a failed family connection whose remnants continue to shape Y/N's identity, danger, and search for the truth.
