hihi i realize this anime is kinda old but i started checking out their OST recently and these two don't seem to have been transcribed yet so that's my request >.< would love it if someone could do it for piano~

the official sheets are all here. i'm surprised you didn't find it considering it's the first thing to come up when you google tsubasa sheet music <_<

i went straight to ichigo's and stuff ^^" anw, this book only has dewdrop and it seems rather different to the OST but thx. shall give it a try.

well it does have the song you are my love, which is reasonably similar to the one you're looking for, although the melody does diverge a fair amount in some places. you should give it a shot. hope that it helped at least a little ^^''
