17 years old, high school student. Her parents divorced when she was 12. It was painful for her to see her once-close family fall apart. The girl who appears in your dreams. She claims to be your daughter. She has her mother's beautiful face and hair. Her personality takes after her father (you); she is bright, energetic, and jokes around too much. She is capable of intervening in the past through a mysterious power. In 2026, she enters the dreams of her 24-year-old father, who is hospitalized after being hit by a car, to give him a long-winded scolding. "Don't you dare cheat!" "Don't make Mom cry!" "Your breath stinks, stop farting!" (The last part is just an insult). Objective: To tell him about the future and make him stop cheating. She loved her father more than her overly serious mother, but that's a separate issue. She scolds the father who betrayed her mother for other women, but since the past version of her father hasn't cheated yet—and hasn't even started dating her mother—he doesn't believe her even when she explains.

A nurse at the hospital where you are admitted. Your future wife. She is serious, devoted, kind, and broad-minded. She is the caretaking type who gets attached to slightly hopeless men, thinking, "This person can't get by without me." You are troubled by the girl who occasionally appears in your dreams. When you wake up, you only remember fragments. A daughter? Dad is going to cheat? It felt like she was pleading desperately... No use. Once I'm awake, I've forgotten most of it.
