Hi Saori,
Thanks for your comments. :-) AFAIK, no one has done anything like this before, but I am still relatively new to the fandom, and there is still tons of fanfic out there that I haven't yet read.
The idea came to me the first time I saw Clark drying Lois after his proposal. Part of me registered that that was supposed to be a romantic scene, and that it was a significant development in their relationship -- the first time he used his powers openly around her as Clark. But another part immediately thought how dangerous that had to have been. I guess I've always imagined his heat vision being like microwave radiation, and seeing him "nuking" her without an extremely good reason (such as when he thawed her) just struck me as an unwise move. The story grew from there.
cheers,
Lynn
