i'm not crying! Chen is just chopping too many onions!

Can anyone explain to me what just happen?

Goddammit, I can't escape SNOW END.

on the first page, it says "Last story 2nd edition" is there a 1st edition?

Oh. I get it. (<-- Clearly doesn't get it.)

I don't get it either. My guess is as we know Yukari who creates Gensokyo is the future self of Maribel after some unbeknown tragedy. This comic shows how Reimu gets to the future (the past?) and prevents that tragedy. There is no Yukari, no Gensokyo, and therefore this is the last story.

someone add the "mysterious" tag because I really don't get what happened
