Awww this is adorable and captures the whole oblivious Taichi so well! Their relationship is so pure and the way you've wrote this "shes a girl!" revelation here just works perfectly with that in my opinion.
Love it :D

This was pretty nice. It sounds exactly like Tai would... kinda wish they'd included something like this in Adventure 02 near the beginning, oh but then that would ruin their apparent Sorato, wouldn't? Anyway, nice POV drabble. Like you, I liked Tai/Sora before anything else.
One typo I noticed in the last sentence: should that be "really like Sora as more than my best friend" instead of "really like Sora as a more than my best friend"?

I really enjoyed this story I love how you just have Tai realizing that Sora is a girl like that. It is just like Tai. I love your story, its well written and has amazing warmth to it but at the same time it has some humor.

Ooh, interesting. I really like the voice that comes out in this one. It's rare to read a first person POV fic on here and actually here the character, but you've managed that. Particularly the subtelties that come across far more prominently in first person, eg. the difference between knowing and i/knowing/i. The way this leads into the scene they share together in the second season is beautiful as well. The comment on poetry was really amusing as well. A lovely piece in all. :D

[Unsurprisingly the first thing...] - for some reason, I'm reading a comma after "unsurprisingly".
