Ho-jung discovered her husband's affair with Jin-hee years earlier. When she confronted Jin-hee, the situation escalated. Jin-hee's insistence on continuing the relationship and her pregnancy pushed Ho-jung over the edge. In a fit of jealousy and rage, Ho-jung pushed Jin-hee down the stairs, killing her. She then hid the body inside a wall and plastered cement over it.

Foreshadowing: Ho-jung's jealousy of Ji-won and her longing for motherhood she never had hints at her deep-seated resentment that led to the murder.

Ji-won is Young-ju's biological mother because she donated her egg to her sister Ho-jung, who was infertile. Ho-jung and her husband used IVF to conceive Young-ju using Ji-won's egg. This makes Young-ju Ji-won's biological daughter, not just her niece, which adds emotional weight to the supernatural threat Young-ju faces.

Foreshadowing: This revelation explains why Jin-hee's ghost targets Young-ju specifically and why Ji-won feels compelled to protect her at all costs.

The ending implies that the curse is not truly broken by simply disposing of the phone. Even though Ji-won throws the phone into the ocean, it continues to ring as it sinks, suggesting the supernatural threat attached to the phone number will persist and potentially claim another victim. The curse extends beyond the house and the immediate family.

Foreshadowing: The recurring theme of the phone number claiming lives throughout the movie foreshadows this inescapable ending.
