When we think of K-Dramas, we can easily think of the Cinderella story: a poor heroine meets an extremely rich hero and becomes a modern princess. A famous screenwriter named Eunsook Kim always fascinates numerous viewers by entertainingly telling this kind of story. When I looked into her most famous works, Lovers in Paris (2004) and Goblin (2016), I discovered that the speech patterns of heroines have changed over time even though the setting of the Cinderella story remains the same. I analyzed dialogues from two dramas, and the analysis showed that a heroine from recent drama Goblin speaks in a more dominant way than a heroine from the older drama Lovers in Pairs. It shows that Kim reflects the change in women’s speech behavior in her script. This reflection is very important because it is a mirror of the time which demonstrate the change in women’s speech behavior in the real world.
