This part continues from Part 2. The eldest sister receives a phone call from a mysterious buyer who is awaiting the arrival of a young girl previously promised to him. However, he threatens to cancel the deal if the girl is not immediately sold and delivered. Panicking, the eldest sister informs the second sister, warning that they could lose a large sum of money if the matter isn’t resolved quickly. The problem is, the young girl is still in the hands of the youngest sister, who treats her like a beloved doll. To avoid losing the deal, the second sister, who had previously allowed the youngest to do as she pleased, now tries to convince her to give the girl up, promising that she will receive an even better one later.
