Really, really nice story... I think the only thing I think would be better is if it was all full-coloured, I'm sure it would make this an incredibly stunning manga. I kind of feel a bit disturbed though... I don't like thinking that I'm like Theo, but "poker-face" or "serious-looking" usually counts as A LOT of +attractiveness points :P
I liked the last two stories that weren't related to this story, The Apple Family and Full-fledged Hook the most. I think that both were good-enough that they could have had their own continuation after the one-shot.
