An's mind was absolutely working overtime in that moment.

..what had gotten into him?

...

An and Akito had been together for nearly two years now. They knew eachother better than they knew themselves, yet it was quite hard for them to engage in affectionate acts most of the time.

It was mostly because of Akito's bad habit to push away the people he cared for. An had still managed to warm up to him, just enough so that he wasn't actively trying to shove her away.

And the first night Akito greeted An with a kiss to the lips, she didn't know what to feel. On one hand, she felt ecstatic. On the other, she was trying to figure out the reason for the change.
