Between father and daughter Mari lies a forbidden secret they can never reveal. This secret is known as incest, something she cannot confess to friends, teachers, or even her mother. When her mother is away, the father forcibly touches Mari's body, and she has no means to resist. Like a dream, Mari's innocent body is gradually transformed into that of a woman by her father's hands. Amid this process, she feels anxiety, fear, and the loneliness of losing her purity. Mari's heart becomes increasingly distorted by daily despair.
