Such an adorable AU... to tell you the truth, I like this, with their problems and struggles, better than if they'd been entirely too happy. Life is hard, for everyone, and nothing can change that. If somebody is entirely too happy and nothing bad ever happens to them... well, it just seems fake.

The key is learning to be happy despite the bad things.

I also liked the way you've included almost everyone, even if under different circumstances (but where is Kohane-chan?)

(and I wonder when clone!Syaoran was shortened to Cloney? I've seen it used more than once. XD)
