What? Yet another update?
I woke up with this idea in my head. I'm not quite happy with the way it turned out, but I think its heart is in the right place.
Also, in case you were wondering, I don't own Bleach. I'm pretty sure that any anime I was in charge of would turn out very differently than Bleach...
And, this contains implicit (maybe slightly explicit) self-pleasure. If that disturbs you, well, move on... :-)
Thought to provide a bit of motivation for why he lets Hina be so damn dependent on him.
Ships Passing…
Aizen Sousuke had a secret.
It was his favorite secret, much loved, much treasured.
Everyone saw Hinamori-kun's strength, her perseverance, which had propelled her to the position of his second-in-command. Nevermind the fact that she wasn't a great fighter—there were other things that mattered, especially to him. But because she had worked so hard, most people thought she was a cute, friendly, robot: the kind of person they would willingly work with, but not really friendship material. She had been so intense on the way up, that now she had found that she had isolated herself from nearly everyone around her. Even her best friends from the Academy, Kira and Renji, were more distant now, though it was mainly due to the fact that she had made lieutenant before them (something which chafed their egos).
And so in a way, Aizen Sousuke had become—and was aware of this fact—the most personal figure in her life, despite being her commander. Moreover, he was the only one privy to her internal life…and he was quite good at reading her moods, even though she tried to cover up her loneliness with her pleasant manner.
He wanted to share this Hinamori with the world. Her sheer sweetness of being, so obvious to him, hid itself from everyone else. How could anyone possibly think she was too intense, too impersonal?
He worried about what she would have, when she no longer had him. Stupid, irrational, but there it was.
Finally, he decided to confront her about her social life. Late one night, impulsively, he had walked over to her quarters, hesitating at the door handle. Dare he wake her? He felt guilty at how long it had taken him to do this…perhaps he could talk to her tomorrow? But then he thought he heard a noise from beyond the door. He paused, and listened carefully.
Muffled though it was, breathy, ashamed, he could hear low sounds, almost like singing, arrayed for his ears in growing intensity. His eyes hardened and he blinked several times, caught between the peaceful world of the night and the obvious pleasure of his little fukutaicho. But at the last, he heard, as gentle as a puff of wind, "Aizen-sama", caress his ears. He withdrew his hand from the door as though it had been burned, swishing away in his captain's haori, deciding in his mind that he would never share her.
He walked away, his heart beating a little faster. But he knew, from the whispers in his blood, that he would return.
And that's that. I imagine this as going unrequited, but the thought of Aizen passing by Momo's door whenever he needs a pick me up is sheer delicious fun.
