What is the true identity and origin of the woman locked in the dungeon? How does the cycle of reincarnation and the curse of incest continue to control this family? Beneath the floorboards of the grandfather's old house, a diary is discovered, filled with the raw confessions of the great-grandmother: "Let's say your husband died in the war... in return, I'll pay you with my body," "Let me touch your breasts, mistress," "Huh... you'll only touch?" As he reads the diary, the man becomes increasingly consumed by emotion, slipping into vivid daydreams. This story reveals how a family's dark secrets and the curses of the past continue to haunt the present.
