This was just beautiful. I could almost imagine the scene of Fuji and his fellows playing in the lake, and Tezuka embracing Fuji lovingly with a peaceful expression on his face. I couldn't help but wonder, that Tezuka is dead (kinda) now, will he be seeing Fuji again? Maybe in his "dream"?

Though I still feel a bit sad for the ending, even Tezuka and Fuji were finally together, that Ayana and Kuniharu has lost their son.

Anyway, this is so beautifully written. You should really write more, especially this kind of fics Ann-chan :)
