It's not as if this story doesn't have some big false notes in it—the one that most stuck out was that the Junker lacked some sort of impetus to change his mind and come back to the planetarium, instead just showing up again—and probably anyone could see Yumemi's final lines coming from a mile away.

But I'm a huge sucker for plots about clinging to hope in spite of everything, and learning to hope in spite of everything, and I'm an even bigger sucker for the dramatic irony of a twist of the knife you know is coming. Especially one already imbued with meaning.

One of the better ways to make yourself cry for two hours.
