Cho Sang-woo: Gi-hun! Your life is so damn pathetic, and here's why. It's because you always gotta open your mouth and ask something idiotic. Because you're a nosy-ass idiot who's too slow to keep it shut. Someone who always has to get into trouble but somehow can't tell he's in it.

Seong Gi-hun: Okay. That's right. That's how I got caught in all this. Because I was slow, crazy incompetent. Just a dimwit who lives off his mother, but you're with me in this place. Isn't that interesting? Why is that? Ssangmun-dong's golden child, the genius Cho Sang-woo, who went to SNU was here? Rolling around this sh*thole, slamming with us, simpletons, huh! Is it my fault that you're here?
