- Kim Soo-hyeon: I will kill you when you are in the most pain. When you're in the most pain, shivering out of fear, then I will kill you. That's a real revenge. A real complete revenge.
- Kyung-chul: Hey. Cut the bullshit. You already lost. You think you got me? Huh? Fuck you. I don't know what pain is. Fear? Don't know that either. There's nothing you can get from me. So... You already lost. Got that?
- Kyung-chul: Why do you look like you stepped in shit? -
- [as his latest victim realizes her predicament]
- Kim Soo-hyeon: Forgive me Ju-yeon. I wasn't there for you, always late. And never there for you. But... I promise you this. I'll make him pay for... your pain.
- Kim Soo-hyeon: Heard that many times, haven't you? People begging for their lives. And you enjoyed that, huh?
- Kim Soo-hyeon: Hands, feet and head... just like you did. Nothing more, nothing less. You stupid sick psychos!
- Kyung-chul: What? You're alone? Are you a cop?
- [Waits for response]
- Kyung-chul: Must be right.
- Kyung-chul: The cops found me this quick?
- Kim Soo-hyeon: You're shitting me.
- Kyung-chul: [laughs] Guess you don't know who you're dealing with.
- Kyung-chul: Damn cops.
- Kyung-chul: What else do you expect?
- [Spits]
- Kyung-chul: Anyways...
