pig

Even today, people still walk while looking at their cell phones. The main character, Young-in, is taking a class but is looking out the window because he is bored. Most students are not taking classes and just looking at iPads and cell phones. In class, the professor says that pigs cannot see the sky. After class, I came to a cafe with Young-in and her girlfriend Zua. Inha brings up the story of pigs to Zua, who is only looking at her cell phone. Then, Zua asks back to Inha, asking if she has gained weight. Inha just sighs. Zua walks from the cafe to Zua's house. Zua looks at her cell phone even as she walks. Young-in asks such Zua, what's the difference between a person who walks while looking at her cell phone and a pig. Zua asks herself if she is a pig. Young-in asks Zua a significant question, what's the difference between a pig who cannot see the sky and a human who does not see the sky. Zua says that humans can always see the sky when watching a video or eating. When Young-in sees such Zua, he asks her what's different from pigs and ends.
