At the end of the day they've got a connection that's irreplaceable, one that can't be replicated no matter how hard one may try. Despite the number of times 9S has been terminated by her hands he's always found himself back at her side, feeling too much and willing to risk everything just for her. 2B brings out the best and worst in him, the obsessive fixation and the delightful tenderness he feels around her. He'd be lying to himself if he said he didn't want to do this and as much as his own programming is urging him to follow through, to put a stop to what's happening and fulfill what he's supposed to do he ignores it.

Her kiss is far too distracting, her smile too potent to him. He can't help being swayed by it and honestly? What's a bit more time when it's been put off this long anyway?

"...After. After we're done doing...whatever we're doing."

Maintenance can wait till then.
