Reality Shock
He's not her biological brother.
There's something important that too much of her wants to remember, but she bypasses it with long practice, burying it easily beneath the shock of the discovery. Her heart is pounding with the news, but she does not allow herself to notice; she'll blame it all on Ryoki, or something.
Hiding from herself has become Hatsumi's defense mechanism, and even if Azusa still knows her better than she knows herself, as long as she keeps herself fooled...
She'll give to Ryoki until she's forced back into reality.
"Hatsumi... Do you want to come live with me?"
Somehow she just knows Azusa will rub it in later.

Uh,
yeah, so this has been on my harddrive for ages... I totally forgot
about it, actually--I have other ficlets, but I'm too lazy to
transcribe them from my notebooks, but they'll come up sooner or later,
if anyone's interested.
