I shut myself in because I'm lonely. Because I don't want to face any more loneliness, I shut myself away. [...] I'm greedier than anyone. I don't want some half-assed happiness. I don't need some partial warmth. I want a happiness that goes on forever. That's impossible, though! I don't know why it is, but in this world, some interference is sure to come. Important things break right away. I've been alive for twenty-two years, and I know at least this much. It doesn't matter what the thing is, but it will break. That's why, from the beginning, it's better not to need anything.
