What a beautiful story! I love your writing for Tenipuri, and especially the way you write Kaidoh. The way he neatly folds his shirt, gets up early to do housework and quietly moves things along the last morning are perfect little bits of characterization.
And I love your Fuji. Like Kaidoh, he's such a complex character. So much more than meets the eye and you really do a great job capturing that.
The way this unfolds, it seems the most natural thing in the world that these two boys would get together. I hope you write more for them.
