It had been so easy… So very easy to manipulate her, when he had been pretending to be the good, kind captain. Hinamori-kun was so willing and it had been so very obvious to him that she had loved and adored the God.

"Yesterday, all my troubles seemed so far away

Now it looks as though they're here to stay

O h, I believe in yesterday"

In Soul Society it was easy to plot and plan, to mastermind and to play things to his design and whims. To make sure that all of her attention was focused solely… Completely upon him. As it should be, as he was her captain, and she had to make sure that she was doing as he wanted her (and no he didn't want her attention just because, that was a ridiculous notion that Gin had stated from time to time and had no bearing in fact).

"Suddenly, I'm not half the man I used to be

There's a shadow hanging over me.

Oh, I yesterday came suddenly"

The look of horror on her face when he stabbed her had haunted his mind for several weeks, and haunted him on nights when he had been overstressed due to the arrancar he had created, or Gin or Tousen or a combination of all three factors. The knowledge that she was healing… Did not appear to soothe his subconscious. Not as much as he had thought that it would… It was also a surprise at how much hurting her had affected the godly being…

"Why she had to go I don't know she wouldn't say

I said something wrong, now I long for yesterday"

She had, for a time after she had woken from the coma she had slipped into, been doggedly trying to 'save' him… To find out what happened to her good, great captain, and had, fascinatingly enough, blamed Gin for his seeming switch to evilness.

But that had begun to change. And that… Did not please Aizen, as it meant that she was moving on… Moving away from him, from being quite so easy to manipulate and use… (and to potentially speak to, if only for a brief moment… Just to see her sweet, honest face light up with joy and love at seeing him. Her affection meant more to her than he would like to admit).

"Yesterday, love was such an easy game to play

Now I need a place to hide away

Oh, I believe in yesterday"

It used to be so easy for her to manipulate her… To get her to smile for him, to laugh and to care for him with her polite but earnest questions, the surprise cookies and other sweets. Perhaps it was because it was her birthday that he was reflecting upon her so…

"Why she had to go I don't know she wouldn't say

I said something wrong, now I long for yesterday"

He had given her small, meaningful gifts as his tenure as her captain… But Aizen had always left the gifts upon her desk, and had always been an anonymous gift giver, as he hadn't been certain as to how she would have reacted to her 'Aizen-taichou' giving her a gift, beyond stuttering while blushing oh, so very adorably.

"Yesterday, love was such an easy game to play

Now I need a place to hide away

Oh, I believe in yesterday

M m mm mm mm mm mm mm"

Aizen had left Soul Society… Hand left one Hinamori Momo, the petite brunette who had almost, but not quite stolen his heart completely. Her haunted eyes, and the pain filled question as to why… Why he had hurt her, and her joyful words still echoed in his mind at times, tormenting the brunette more than the powerful male had ever thought he would have…
