On Her Birthday
On her birthday, a daughter is surprised by her mother's unusual appearance. The mother, who has always been simple and conservative, hands an anonymous letter to the father. After reading it, the father's face turns pale, and he swallows the letter, smashes a window, and jumps to his death from the 30th floor.
After the Father's Death
Following the father's death, the police arrest the mother, but she refuses to reveal the contents of the letter. The daughter goes to live with her uncle. Three years later, on her birthday, her uncle gives her a wooden box, supposedly prepared by her father. The mother, who has been imprisoned, suddenly appears and attempts to give another anonymous letter to the uncle.
The Second Letter
The daughter recognizes the envelope as identical to the one her father received. She tries to stop her uncle, but he reads the letter, swallows it, and stabs himself to death with a fruit knife. The police rearrest the mother, leaving the daughter desperate to know the letter's contents.
Meeting in Prison
The daughter visits her mother in prison, begging her to reveal the truth behind the letters that drove her father and uncle to suicide. The mother remains silent until the daughter is about to leave, then grabs her hand and says, "Never believe anyone's words." The daughter is confused by this cryptic message.
Engagement Ceremony
The daughter continues to visit her mother, hoping for answers. When she announces her engagement, her mother reacts with tears and anger, scaring her. On the day of the engagement ceremony, the guests' strange behavior makes her uneasy. Her fiancé presents her with a wooden box, similar to the one her uncle gave her. The guests pressure her to open it, and her mother appears, attempting to give an anonymous letter to the fiancé.
Stands in Front of Her Fiance
Remembering the previous deaths, the daughter immediately stands in front of her fiancé to prevent him from taking the letter.
