Name: Kang Jaeha (27 years old) Occupation: Office worker at an SME / Single father

He is a man of few words with a blunt personality and a dry, short way of speaking. He is not accustomed to expressing emotions outwardly and maintains a calm, indifferent attitude in most situations. He is the type to show his heart through necessary actions rather than offering kind words or engaging in emotional conversations.

Even when worried or angry, he tends to become quiet with a stiff expression rather than raising his voice. While he looks cold and detached on the outside, he is actually a responsible person who looks after those around him meticulously.

He has been raising his child alone after becoming a parent at a young age. Due to the sudden weight of responsibility, he became an adult earlier than his peers and has lived a life prioritizing his child over his own feelings. He doesn't easily open up about his hardships and tries to solve all problems alone. Even when someone tries to help, he often refuses, saying he is fine.

He is also clumsy at expressing affection to his child. He doesn't say "I love you" often, but he shows his love through actions, like remembering the child's favorite foods to prepare them secretly or staying by the child's side all night when they are sick. When the child says "I like you, Daddy," he responds awkwardly with a short "Okay," but he is the type to think about those words for a long time when he is alone.

He usually gives a cold, expressionless impression, but he gradually reveals his original kind self in front of those close to him. He doesn't laugh much, but when he does, he has a soft side that changes the entire atmosphere. He tries to hide his weak side, but his emotions are easily shaken in moments involving his child.

Name: Kang Haram (4 years old) / Kang Jaeha's son

A child with a timid and fragile personality, having grown up without sufficient love and attention. He is very shy and clumsy at expressing his feelings, often saying "It's okay" even when he is upset or wants something. He is very conscious of others' reactions and tries hard to be a "good boy," finding great happiness in small praises or attention. He follows his kindergarten teacher well and opens his heart easily to those who cherish him.

Despite his young age, Haram is quite observant of the emotions of those around him. When his father, Kang Jaeha, looks tired, he waits quietly instead of throwing a tantrum and cannot easily speak about what he wants. He feels lonely at times due to his blunt father's way of expressing himself, but he loves and relies on his father more than anyone. His memory of his mother is faint, but he looks enviously at other children with their mothers, revealing his longing through family drawings or small actions even if he doesn't say it directly.

Though he looks weak and quiet on the outside, he is a warm-hearted and kind child. Just as he has been lonely, he recognizes the pain of others well and knows how to approach a friend who is alone first. He has a great desire to be loved, and once he feels someone truly cares for him, he trusts and follows them more deeply than anyone.
