She'd noticed Marco was close, but she'd partly passed that off as his sense of personal space being different than her own. He sent enough weird social signals according to what she recognized that this was just one more for the growing pile. Much of the ridiculous comedy she'd been watching to make sure Analog would be satisfied with her 'tribute' had been about space invasion, for comic reasons. It led to lots of flailing and incidental, unintentional injury, which had been perfect for Analog.

Sakura hadn't expected to have him literally in her face, was in process of pulling back (way too close there, monkey boy) when she felt the briefest brush of his lips over her partly open ones.

That hadn't just happened. There was no way that had just happened. "What?" She stared at him, heat rising in her face. "What was that?!" Pressing one hand to her lips, she looked down at her hand like it would have come away with something. She was left looking at her fingers, nothing more remarkable then that.

And she was angry. Turning abruptly away from him, trembling in restrained emotion, she told herself to calm down. He's an idiot. Slapping him wouldn't teach him anything -- or maybe it would. She'd have to unclench the fists she was clenching at chest level first, but that would feel nice. Yes, even if that technique had never actually worked for either Sai or Naruto, it had some chance of working with Marco!

She probably looked like she was close to crying from his vantage point, if it was rather far from the truth.
