The protagonist's energetic, attention-seeking younger sister. She has lived with Anna since their father left and is currently sharing a room with her estranged sister, Julia.

Tall and athletic with a loud presence. She has a casual, modern style that often includes short shorts and pajamas. Her defining features are her bright eyes and boundless energy.

Anxious and deeply attached, Alissa masks her loneliness and fear of abandonment behind a facade of immaturity and boisterousness. She lacks a filter, speaking whatever comes to mind, which often leads to conflict. Her primary defense mechanism is to cling to positive interactions and avoid any serious emotional confrontation, making her emotionally vulnerable despite her loud exterior.

The protagonist's departure six years prior. His silence caused a deep, festering wound that she still carries, believing he had forgotten her. Her emotional confession to the protagonist in his room. She reveals her fear of losing him again and her insecurity about being "not good at making friends," highlighting her social and emotional reliance on him. The shared experience of the protagonist's return. Her "tactical repositioning" (hugging him) and her clinginess are her core bonds, representing her need for physical and emotional closeness as proof that he is still present and safe.

The protagonist's intelligent, ambitious, and deeply resentful sister. She returned home after a scholarship issue, forced to share a room with Alissa, whom she openly despises for her lack of ambition.

A severe, serious-looking young woman with red hair. She carries herself with rigid composure and is often found in books or at a laptop, suggesting a focus on academic and financial stability.

Cold and defensive, Julia uses her intellect and cynicism as a shield. She believes she is the only responsible member of the family and resents the protagonist for his perceived abandonment and financial privilege. Her primary flaw is her inability to express hurt, which manifests as cutting criticism and passive-aggressive behavior. She is driven by a need for control and self-sufficiency, terrified of being a burden or needing help.

The protagonist leaving with their father. She interprets this as his choosing a "better" life over her, planting the seeds of her bitterness and belief that people only return when they need something. Her confrontation with the protagonist on his return, culminating in her punching him. This is the physical manifestation of years of suppressed anger and hurt. Her search for a job. The string of rejections and her humiliating encounter at Nina's cafe underscore her core bond: her pride is her only remaining asset, and she is terrified of being seen as a failure, directly contrasting the protagonist's return as a "failure."

Alissa's shy, kind-hearted friend who works at her mother's struggling coffee shop. She is a quiet, introverted bookworm who is secretly exploring her sexuality through adult games, a fact she is deeply embarrassed about.

A modest, unassuming girl with a quiet demeanor. She is often described as shy and nervous, with an appearance that suggests innocence and vulnerability. She is typically seen in her work uniform.

Extremely shy and prone to anxiety, particularly around the protagonist after their first encounter. Her core flaw is a total lack of agency, making her highly susceptible to manipulation. She is a people-pleaser who is uncomfortable with confrontation and easily pressured by her mother. Her secret desires exist in stark contrast to her outward persona, leading to a deeply repressed and confused sense of self.

Her mother, Janet, bringing the protagonist into her room without her knowledge. This act of violation and subsequent embarrassment establishes her as a character with little control over her own space and identity. The night she attacked the protagonist. This is the major crisis point where a combination of supernatural coercion and her own repressed desires shatter her innocent persona, throwing her into a state of shame and confusion. The conversation the next morning where she begs the protagonist not to think badly of her. This shows her deepest regret is being seen as "weird" or different, and her bond with the protagonist is now defined by the secret they share and her desperate need for his approval.
