"... Do you think you can do that? Do you love Naoko that much?"
"I'm not sure," I said honestly. "Like Naoko, I'm not really sure what it means to love another person. Though she meant it a little differently. I do want to try my best, though. I have to, or else I won't know where to go. Like you said before, Naoko and I have to save each other. It's the only way for either of us to be saved."
