It's the first time we've seen the two of them together, and they're in a public place together. They're walking down the street, and it's obvious that the two are having an affair. The narrator tries to get the two to stop talking, but they just keep walking. He's worried that they'll get into a fight if he tries to stop them, and he's also worried about the fact that he'll have to tell Eunsung what's been going on. He wonders if he should just stop talking about her, since she's just a "gold digger" .
