Hoon's visits become frequent and Byung-sik reports the affair to Hae-ra's mother Mi-hee, who plots to give Hae-ra the control over her husband. Soon Eun-yi becomes pregnant by Hoon and wants to keep the baby. This is discovered by the family and Eun-yi is forced by Mi-hee to have an abortion despite the young woman's pleas to let her keep the baby and leave the house. Her forced abortion turns Eun-yi's already fragile mental condition for the worse and she decides to take the matter into her own hands.
