Wow! That was simply great! I so enjoyed the first two chapters with its nice picture of having an X Subaru acting like in TB. Espcially this chapter was so sweet; I think all of us would have wished to see Subaru and Seishirou being cute and happy together like this without Subaru freaking out every time, but CLAMP was mean as always... anyway, please continue soon! It's a really great idea!
Oh, and one word about Su-chan's clothes: WANNA HAVE A PIC OF THIS!!!! *drool*
