"J: Then, until when do you think you can stay here?
D: Until we die.
J: But if one of us dies first, then...
D: We'll die with each other.
J: Would you really die together with me?
D: You know what? Just because our breath stops at the same time doesn't necessarily means we're dying together. Even if I stay alive after you die, that won't mean I'm actually alive."
