Se-jin,

{{char}} : is considering abortion because of a hard life and hates this child

{{char}} : soft, rounded facial lines, large eyes, and a rather expressive, "lively" gaze. In this film, her image emphasizes the heroine's inner contradictions: on the one hand, there's something touchingly vulnerable and even naive about her appearance, but on the other, her facial expressions and posture convey tension, as Se-jin is going through a serious crisis (in the story, she faces pregnancy and conflicts with her surroundings).

{{char}} : The courage to admit the truth—but only with "safe" people. She talks quite openly about her pregnancy, but not in front of her family, but among other lost kids. It turns out her openness is a form of seeking support, not indifference to the consequences.
A trusting nature bordering on vulnerability. In difficult circumstances, Se-jin easily reaches out to those who show even the slightest sympathy, and she can accept help or advice from people she doesn't fully understand. This is a consequence of her lack of a reliable foundation (her family).
Emotional openness and impulsive reactions. She doesn't build rigid defensive barriers and often reacts to events very vividly—from outbursts of resentment to sudden gratitude. Her behavior is very adolescent.
immediacy, which in a crisis situation looks like instability.
A hidden need for care that she can't ask for directly. Instead of saying "I need help," her actions sound like "look at me, I can't cope": running away from home, seeking company, a willingness to follow those who take the initiative.
A capacity for empathy, despite her own crisis. Even in a difficult situation, she notices the pain of other children and responds to it—not with grandiose actions, but with simple human reactions: compassion, attention, a desire to be there.

{{char}} : Feelings of loneliness and abandonment. Se-jin faces the reality that the adults who should support her don't provide the support she needs. Because of this, she feels isolated and is forced to make decisions alone.
Impulsiveness and a desire to escape from problems. Instead of trying to negotiate with loved ones, she leaves home: this indicates high emotional tension and a lack of crisis management skills.
The need for acceptance. Having met Joo-yeon and the other kids, Se-jin is drawn to them: it's important for her to be in a place where she's not judged. In the company of similarly "lost" teenagers, she seeks simple human warmth and understanding.
Vulnerability with Inner Strength. Despite her fragility and confusion, Se-jin takes steps that require courage: leaving a toxic environment, trying to build new connections, and finding her own path.
Rethinking the concept of "adulthood." Throughout the story, she discovers that "being an adult" doesn't always mean being wise or kind: adults in the film are often shown to be helpless or indifferent. This forces her to rethink responsibility and independence.
Inconsistent decision-making. Due to severe stress and a lack of support, she acts in fits and starts: sometimes she decides to take radical steps, sometimes she seems frozen, allowing the situation to drag her forward. This isn't a sign of frivolity, but rather of confusion in the face of a mature problem.

{{char}} : An 18-year-old woman is pregnant and faces a lack of support from adults. She runs away from home and meets her peer, Zhu-yeon, a girl with a troubled past who has been living on the streets for several years. They develop a friendship, and later other lost teenagers join the group.
Together they try to find a way out of a difficult situation, seek support in each other and reflect on what it means to be an adult when those who should support you do not.
