...you not only look up a character's birthdate --[Spoiler (click to open)]and realize you totally forgot he was born in January -- you look up what sort of climate it would take to have a certain plant bloom on his birthday.
I'm working on one of my celebration pieces right now (I only have a few hundred words right now), and so far, it is tentatively called "One Day At A Time - SIDE A" (I inted to write two parts, in the same way that I wrote "One More Night"). I'll actually post it on my website and my fanfiction.net account when I reach that point in the story --it's a scheduled side-story, thank you very much, haha-- but you guys will get to see it first, if I can manage to work all of the kinks out of it >.<
Anyway, one of my primary characters in the story has flowers blooming on his birthday (it's a difficult month to keep them blooming >.<), so I actually now have a vauge general region in which Nigotta and Kōsei exist.
Also, sorry, but it seems to be a gay, gay world in my mind. Yay for another male/male pairing?
Hey, on the bright side, the other extra is a yet-to-exist scene in "One Trick Pony" and it's just being written because it will be massively amusing to read (and write).
Anyway! I'm gonna get back to working on it, so I'll check back in later, 'kay?
